“…However, the hybrid with one white-flowered cultivar revealed one translocation and a paracentric inversion, implying chromosomal repatterning within C. arietinum. C. echinospermum on the other hand, yielded completely sterile hybrids with C. reticulatum and C. arietinum (Ladizinsky & Adler, 1976a). Further work by Ladizinsky & Adler (1976b) spernium, C. reticulatum; Group II: C. bijugum, C. judaicum, C. pinnatifidum; Group III: C. cuneatum).…”

Karyotypic and feulgen microdensitometric measurements show that the most asymmetric karyotype is correlated with the lowest DNA amount and vice versa in seven annual species of Cicer. The 2C nuclear DNA amounts vary from 1.83 pg to 3.57 pg and the values within this range can be categorized into three groups, the means (1.83 pg, 2.59 pg, 3.41 pg) of which are separated by the regular intervals of 0.8 pg. The differences within the groups are insignificant while those between groups are significant, C. reticulatum, which is considered to be progenitor species of C arietinum, differs from the latter in having two satellite pairs instead of one and 22.3 per cent less DNA content. The possibility of such concrete changes occurring during domestication, and the fact that C. arietinum depicts uniform karyotype and DNA contents in its cultivars underlines the need to reconsider the issue of C. reticulatum as the wild ancestor of C. arietinum.

“…Ladizinsky & Adler (1976a) were able to produce fertile hybrids with perfectly normal meiosis between C. reticulatum and four purple-flowered cultivars of C. arietinum. However, the hybrid with one white-flowered cultivar revealed one translocation and a paracentric inversion, implying chromosomal repatterning within C. arietinum.…”

“…Major differences consist in the arm ratio. In Vigna, as in other leguminous species, at least in Cicer, the evolution process has gone forward through the accumulation of pericentric inversions that have involved different chromosomes (LADIZINSKY and ADLER 1976;VENORA et al 1995b).…”

SUMMARY -The work refers on karyotypic analysis of mitotic chromosomes carried out on 11 wild taxa of Vigna unguiculata (L.) Walpers, by means of image analysis. Low degree in karyological variability was found. The results are in agreement with those obtained through hybridisation investigations carried out between the cultigen and its wild relatives. The data further confirm that despite cowpea is characterised by a high morphological variability, such a diversity is not accompanied though by similar chromosomal variation. The work also indicates the possibility to distinguish each accession thanks the presence of «marker chromosomes». For each accession the Stebbins's symmetric index was estimated. Each karyotype was compared with all the others through Resemblance between chromosomes (REC) and Symmetric indices (Syi) indices which allowed to represent karyological matchings.

“…The presumed ancestral forms and evolutionary patterns of chickpea [49], maize [50], wheat [51] and soybean [52,53] have been identified and established by studying the electrophoretic variability of their respective seed proteins. Gepts [54] used phaseolin as an evolutionary marker in his insightful review of the domestication pattern and world-wide dispersal of the French bean.…”

Abstract:Phaseolin is the salt-soluble glycoprotein or the group of polypeptides of the French bean (Phaseolus vulgaris L.) that account for some 50% of the total protein in mature bean seeds. It was one of the first plant proteins to be translated in vitro from mRNA and one of the first plant genes isolated. It was also the first developmentally regulated plant gene to be expressed in a heterologous plant species through Agrobacterium-mediated transformation. Studies on phaseolin have provided insight to many aspects of plant protein synthesis, from fundamental molecular mechanisms to practical goals such as the improvement of the French bean's nutritional quality. The present review is a comprehensive account of the structural and functional features of phaseolin that have implications regarding its evolution. Additionally, future directions in phaseolin evolutionary studies and suggestions regarding effective and safe biotechnological approaches for the nutritional improvement of French bean seed are outlined.
