Title: Characterizing the molecular and morphophysiological diversity of Italian red clover Authors: Pagnotta, Mario Augusto; Annicchiarico, Paolo; Farina, Anna; Proietti, Sandro Abstract: Red clover (Trifolium pratense L.) is the third major forage species in Europe, but there is limited information on the biodiversity and the genetic structure of landraces and natural populations which evolved in this region. The objective of this study was producing such information for Italian germplasm on the ground of molecular and morphophysiological diversity. The study included 16 Italian natural populations from a wide range of environments, four landraces representing the four traditional commercial ecotypes, and two varieties. Eight morphophysiological traits were assessed in a replicated trial under field conditions, whereas two AFLPs primer combinations with 140 polymorphic markers were recorded on a random sample of 13 genotypes per population. Ordination and classification results based on morphophysiological data clearly kept track of the type of germplasm (i.e. landrace or natural population) and its geographic origin, unlike results based on molecular markers. Euclidean distances among populations based on morphophysiological traits were not correlated with Nei’s genetic distances based on molecular markers according to Mantel’s test. Geographical distances among landrace or natural population material was correlated with distances based on morphophysiological traits but not with those based on molecular markers. The average within-population variation stimated via molecular markers was about 2.6-fold higher than that among populations, preventing an acceptable discrimination among most populations. On average, natural populations tended to have within-population variation similar to varieties and somewhat lower than landraces. Our results have implications for collection, conservation, exploitation and registration in a sui generis system of red clover genetic resources.

Title: Recovery, morphological and molecular characterization of globe artichoke ‘Romanesco’ landraces Authors: Crinò, Paola; Tavazza, Raffaela; Rey Muñoz, Nestor A.; Trionfetti Nisini, Paola; Saccardo, Francesco; Ancora, Giorgio; Pagnotta, Mario Augusto Abstract: The ‘Romanesco’ globe artichoke is of substantial economic importance for Italy, its major world producer. The widespread adoption of single early uniform micropropagated clones has led to erosion of local genetic resources. In an attempt to characterise landrace diversity for future breeding activities and/or germplasm conservation, a set of 19 clones derived from plants cultivated in traditional areas of Latium region were typed using a combination of morphological traits (UPOV descriptors) and DNA markers (AFLP and ISSR). Principal Component Analysis and significant correlations among some of the morphological traits showed that a reduced number of descriptors could be used efficiently to discriminate between the clones. Stepwise regression analysis identified a number of significant and consistent associations between certain morphological characters and marker loci. Heritability for important economic traits were computed; moreover, remarkable clones for future breeding activities were recognized. The variability present within the farmers’ fields is an important factor in the design of a rational strategy of in situ germplasm conservation.

Title: Genetic Resources of Cynara spp. an AGR GEN RES European Project CYNARES Authors: Pagnotta, Mario Augusto Abstract: The European Commission (Directorate-General for Agriculture and Rural Development under Council Regulation (EC) No 870/2004), has sponsored the European Project ‘CYNARES’ for the characterisation and conservation of Cynara species germplasm, focusing predominantly on artichokes. The project (2008 – 2012)involves seven project partners from France, Spain and Italy which share European germplasm collections. The accessions are currently being assessed at the morphological, biochemical and molecular levels as well as for disease resistance. Policy aspects addressed within this project include patenting resources to increase value to farmers producing well-recognised varieties and with known nutriceutical values. Moreover, European germplasm will be assessed, classified and patented hence protected by the third country, to avoid fraud and valorise the European products; three clones have already been sent for evaluation by registration authorities in Italy. The conservation of Cynara spp. germplasm and its utilisation are crucial to the project and were developed based on the CBD, the FAO’s GPA for PGRFA, and the ITPGRFA. A CYNARES website documenting Cynara germplasm with project updating and information is available at: http://www.cynares.com/ or http://www.cynares.eu/. The site will also target farmers as well as other stakeholder needs. The website aims to be a focal point for all the activities related to Cynara spp. Anyone can register and contribute to the news updating, inserting scientific results, germplasm information or events announcement.

Title: Genetic diversity of Syrian pistachio varieties evaluated by AFLP markers Authors: Ibrahim Basha, Amer; Padulosi, Stefano; Chabane, Kamel; Hadj-Hassan, Adnan; Dulloo, Ehsan; Pagnotta, Mario Augusto; Porceddu, Enrico Abstract: Pistachio (Pistacia vera L.) is a strategic nut tree species in the Middle East which holds comparative advantage over other fruit trees in view of its hardiness, income generation opportunities and benefits for the ecosystem. Yet pistachio cultivation depends on a very narrow genetic base, in spite of the existence of many varieties still marginally exploited. Syria is an important center of diversity for pistachio. A country wide ecogeographic survey in this country was carried out to determine the extent of pistachio genetic diversity and its use. As a whole, 114 accessions were collected from 37 farms to assess diversity at morphological and molecular level. Molecular evaluation was carried out using Amplified Fragment Length Polymorphism (AFLP) technique and performed using seven primer pair combinations. Results from the studies allowed the identification of 25 pistachio female varieties in Syria, some of which unique and described for the first time. Three groups of pistachio diversity were identified by cluster analysis which provides useful information about the distribution of genetic diversity in Syria for enhanced use and sustainable conservation.

Title: Analysis of durum wheat germplasm adapted to different climatic conditions Authors: Mondini, Linda; Farina, Anna; Porceddu, Enrico; Pagnotta, Mario Augusto Abstract: A study of the extent and patterns of microsatellite diversity in 234 genotypes from Ethiopian durum wheat (Triticum turgidum) landraces was conducted to identify areas of diversity that could be used as a source of new germplasm for developing high yielding and stable varieties. Landraces belonging to nine populations, from three Ethiopian regions [Tigray (T), Gonder (G) and Shewa (S)] with different climates, were analysed by using 28 simple sequence repeat (SSR) markers. The level of polymorphism was high and quite consistent among populations underlining the great diversity existing. The highest level of diversity was found within populations, about 75.9%, while about 5.3% was attributed to differences between regions. The level of expected heterozygosity was on an average, rather high, ranging from 39% to 56%, whereas the observed heterozygosity was, on an average, limited to 14%. An average of about five alleles per locus was detected in each population. Nevertheless, alleles were not equally present in populations as confirmed by the high level of expected heterozygosity. The polymorphism information content (PIC) for the markers assessed showed a wide range of values from 0.14 to 0.92. The likelihood relationships among the nine Ethiopian populations indicated that thematerial collected in the Gonder region (a wet climate) was genetically more diverse than the materials from Shewa and Tigray (dryer climates). The high number of loci in linkage disequilibrium (LD), up to 23, has demonstrated that the loci were associated irrespective of their physical location. This holds true even if the loci are located on different chromosome arms. Genetic diversity values between populations was very different and was used to produce a dendrogram showing population relationships.

Title: Molecular linkage map for an intraspecific recombinant inbred population of durum wheat (Triticum turgidum L. var. durum). Authors: Nachit, Miloudi M.; Elouafi, Ismahane; Pagnotta, Mario Augusto; El Saleh, A.; Iacono, E.; Labhilili, Mustapha; Asbati, A.; Azrak, M.; Hazzam, Hani; Benscher, David; Khairallah, Mirelle M.; Ribaut, Jean Marcel; Tanzarella, Oronzo A.; Porceddu, Enrico; Sorrells, Mark Earl Abstract: Durum wheat (Triticum turgidum L. var. durum) is an economically and nutritionally important cereal crop in the Mediterranean region. To further our understanding of durum genome organization we constructed a durum linkage map using restriction fragment length polymorphisms (RFLPs), simple sequence repeats (SSRs) known as Gatersleben wheat microsatellites (GWMs), amplified fragment length polymorphisms (AFLPs), and seed storage proteins (SSPs: gliadins and glutenins). A population of 110 F9 recombinant inbred lines (RILs) was derived from an intraspecific cross between two durum cultivars, Jennah Khetifa and Cham 1. The two parents exhibit contrasting traits for resistance to biotic and abiotic stresses and for grain quality. In total, 306 markers have been placed on the linkage map – 138 RFLPs, 26 SSRs, 134 AFLPs, five SSPs, and three known genes (one pyruvate decarboxylase and two lipoxygenases). The map is 3598 cM long, with an average distance between markers of 11.8 cM, and 12.1% of the markers deviated significantly from the expected Mendelian ratio 1:1. The molecular markers were evenly distributed between the A and B genomes. The chromosome with the most markers is 1B (41 markers), followed by 3B and 7B, with 25 markers each. The chromosomes with the fewest markers are 2A (11 markers), 5A (12 markers), and 4B (15 markers). In general, there is a good agreement between the map obtained and the Triticeae linkage consensus maps. This intraspecific map provides a useful tool for marker-assisted selection and map-based breeding for resistance to biotic and abiotic stresses and for improvement of grain quality.

Title: Volatile compunds from leaves and flowers of Bituminaria bituminosa (L.) Stirt. (Fabaceae) from Italy. Authors: Tava, Aldo; Pecetti, Luciano; Ricci, Marina; Pagnotta, Mario Augusto; Russi, Luigi Abstract: The volatile fraction of Bituminaria bituminosa (L.) Stirt. was isolated by steam distillation from fresh aerial tissues and analysed by GC and GC–MS. Leaves from six accessions collected in central and south Italy and flowers from a single accession were used in this investigation. The yield in essential oil from the leaves and flowers was 0.1–0.3% and 0.2% of fresh material, respectively. A wide range in volatile quantitative composition was detected. Alcohols and sesquiterpenes were identified as the major compounds in both types of tissue samples. The former constituted 36.6–62.3% of the total leaf oil and 53.0% of the flower oil; the latter, 18.1–31.5% of the leaf oil and 13.7% of the leaf oil and 13.7% of the flower oil. Hydrocarbons (4.3–9.1% in leaves, 7.6% in flowers), phenolics (4.3–7.8% in leaves, 2.6% in flowers), furanocoumarins (3.0– 4.7% in leaves, 4.9% in flowers) and monoterpenes (1.4–2.9% in leaves, 1.9% in flowers) were also detected. Aldehydes, sulphurated compounds, esters, acids and miscellaneous compounds, together constituting 1.1–5.1% in the leaves and 4.7% in the flowers, were also identified and quantified in lower amount. The presence of furanocoumarins, phenol derivatives and sulphurated compounds were detected for the first time in the volatile oil from this species. A possible relationship between volatile chemical composition and the characteristic, strong ‘oil’ odour of this species is discussed.

Title: Variation in forage quality and chemical composition among Italian accessions of Bituminaria bituminosa (L.) Stirt. Authors: Pecetti, Luciano; Tava, Aldo; Pagnotta, Mario Augusto; Russi, Luigi Abstract: Native Bituminaria bituminosa (L.) Stirt. accessions from central and southern Italy were evaluated for chemical composition to assess their nutritional value as forages. The germplasm was evaluated subjectively ex situ for intensity of ‘oil’ smell and analysed for fibre fraction, crude protein and water-soluble carbohydrate contents as well as furanocoumarin (psoralen and angelicin) concentration. Total phenolics and their antioxidant activity were also evaluated. The quality parameters indicated this species as a good forage source, showing nutritive values similar to those of other wild legume species. Psoralen and angelicin contents ranged from 2.8 to 5.4 and from 2.3 to 4.7mgg−1 dry weight respectively, while total phenolic concentrations were between 11.2 and 13.5mg g−1 dry weight. Correlations among forage quality parameters, chemical components and climatic features at sites of origin were also assessed.

Title: Morphological and molecular characterization of Italian emmer wheat accessions Authors: Pagnotta, Mario Augusto; Mondini, Linda; Maroun, Fandy Atallah Abstract: The characterization of 39 Italian ecotypes and cultivars of Triticum turgidum L. spp. dicoccum Shrank ex Sch¨ubler (emmer wheat) was performed utilizing agro-morphological and molecular tools. Emmer wheat is a hulled species which grows wild in the Near East and is still cultivated in the Mediterranean Basin. Due to its characteristics, in Italy it is cultivated mainly in marginal lands of central and southern Italy, where local varieties, adapted to the natural environment where they originated, are used. Emmer wheat cultivation has been drastically reduced during the last century as a consequence of its low yield. Nevertheless, more recently, its agronomic and nutritive values, together with its use in health food products, made its cultivation economically viable in the marginal lands with a parallel increase of the cultivated area which is now more than 2000 ha. In the present paper the results of morphological evaluation, carried out in an experimental field in central Italy using a randomized block design with three replications, and molecular characterization are reported. The analysed material showed distinctive molecular traits and the existence of a huge amount of diversity not only between varieties, but also within them. When the accessions were clustered utilizing their genetic distance, the clusters were not always in agreement with the accessions origins. The obtained results gave information that can be useful for: (i) future registration of material, ii) germplasm conservation and (iii) use of this valuable source of emmer germplasm for future breeding programmes.

Title: Evaluation of perennial legumes collected in Italy: First year data Authors: Pagnotta, Mario Augusto; Bennett, Sarita Jane; Cocks, Philip S.; Ewing, Mike A.; Howieson, John; Moore, G.; Norman, Hayley; Nutt, Brad; Porqueddu, Claudio; Russi, Luigi; Snowball, Richard Abstract: Ecotype variation was studied between and within different perennial legumes species collected in three Italian regions: Calabria-Sicily, Tuscany-Lathium-Umbria, and Sardinia. The germplasms have been evaluated at the Tuscia University’s experimental field in a randomised block design with two replications, each plot consisted of about 12 plants. Eighteen morphological characters have been evaluated and analysed using analysis of variance, principal components analysis, and discriminant analysis, correlation between morphological characters and edaphic factors of the collection sites were performed. The analyses were run both considering all the species of the trail, and focusing only on the species with more accessions, i.e. Trifolium pratense, Medicago lupulina and Lotus. The major differences were, as expected, between species, but there were also some statistical differences between accessions. There were weak correlations between morphological characters and environmental conditions of the collection site. Considering all the evaluated collection as a whole, the environmental factor with the highest number of correlations was pH; it affected the plant structure (petiole length and internodes), the flowering time and seed production. Some of the species did not flower at all as Astragalus monspessulanus, Trifolium hybridum, and Argyrolobium zanonii. M. lupulina was the earlier species, while Lotus was later beginning to flower in June. Utilizing a discriminant analysis with all the characteristics recorded and the species as a grouping strategy, it was possible to monitor the similarity between species. Some species were very similar as, for example, the clovers and the Lotus, whereas other were sharply different as, for example, Psoralea bituminosa.

Title: Ecogeography of Perennial Legume Collecting Missions in Italy Authors: Russi, Luigi; Bennett, Sarita Jane; Pagnotta, Mario Augusto; Norman, Hayley; Nutt, Brad; Porqueddu, Claudio; Cagiotti, Mauro Roberto; Snowball, Richard; Moore, G. Abstract: An ecogeographic survey was conducted in three regions of Italy in 1999. The three regions selected for the survey were central Italy, Sicily and Calabria, and Sardinia. A total of seventy-nine sites were visited across the three regions in May when the botanical composition of perennial legume species was documented, including recording companion annual species. Detailed ecogeographic information was collected at each site, and soil samples were taken for later laboratory analysis. Climate data for each site were obtained from the Central Bureau of Agricultural Ecology. The sites were revisited in July to collect seed of the perennial species. One hundred and forty-seven legume species were identified, fifty-two of which were perennial. The most common perennial species were Trifolium pratense, T. repens and Lotus corniculatus, and these were also found to be the species with the widest distributions. Species distribution and site variability was analysed using #-rneans clustering. This identified eleven different climate clusters and nine soil clusters. Particularly acid soils were rare. Cross-tabulation of soil and climate clusters resulted in several environment combinations, which could be explained by geography to a limited extent. The results obtained in this study provide useful preliminary information in the search for perennial legumes for the farming systems of southern Australia, particularly in areas with acid soils.

Title: HRM technology for the identification and characterization of INDEL and SNPs mutations in genes involved in drought and salt tolerance of durum wheat Authors: Mondini, Linda; Nachit, Miloudi; Porceddu, Enrico; Pagnotta, Mario Augusto Abstract: WRKY transcription factors are one of the largest families of transcriptional regulators and form an integral part of signalling webs which modulate many plant processes, such as abiotic stress tolerance. In the present paper, an innovative method has been applied to identify novel WRKY-1 alleles involved in the responses to salt and drought stresses in Triticum durum. This technique involves scanning for sequencing variations in cDNA-derived PCR amplicons, using high-resolution melting (HRM) followed by direct Sanger sequencing of only those amplicons which were predicted to carry nucleotide changes. HRM represents a novel advance in detection of single-nucleotide polymorphisms (SNPs) by measuring temperature-induced strand separation of short PCR amplicons. The use of this approach is still limited in the field of plant biology. Here, HRM analysis has been applied to the discovery and genotyping of durum wheat SNPs. Specific primers have been designed, starting at multi-alignment of WRKY-1-conserved portions. The PCR amplicons, containing single SNPs, produce distinctive HRM profiles, and by sequencing the PCR products identified, SNPs have been characterized and validated. The results showed that all the revealed SNPs are located on salt-tolerant varieties, confirming their value in breeding activities.
