“…Significance of seed storage proteins in cultivar differentiation was suggested in species like Cucumis melo and Citrullus lanatus [32] and in Oryza sativa [27]. Karyotype analysis had also been successfully employed in assessing taxonomic relations in the species of Boronia [25], Carthamus tinctorius [18,34], Prunus [14] and in Allium [20]. The technique has been proved useful at intra-specific levels too [19,33,35].…”

Karyotype and SDS-PAGE analysis in three accessions each of Passiflora edulis; P. edulis Sims. f. flaviocarpa O.Deg -yellow passion fruit, P.edulis f. edulis -purple passion fruit, and P.edulis 'Panama Red', and in three varieties of the wild species, P. foetida, P.foetida var. foetida, P.foetida var. hispida, and P. foetida var. gossippifolia, were carried out to study the genetic diversity in the species. Analysis of root tip cells revealed the presence of 2n=18 in P.edulis, 2n=16 in P.foetida var. foetida, and 2n=20 in P.foetida var. hispida and P.foetida var. gossippifolia. The somatic chromosome number of two varieties viz, P.foetida var. hispida, and P. foetida var. gossippifolia are reported for the first time. Karyotype analysis and SDS-PAGE protein profiling suggest variations at the intra-as well as interspecific levels in Passiflora. Low TF% i.e., 40 % observed in varieties of P. edulis point to the evolved nature of the cultivated taxa. Unique protein bands in P. foetida (65.66KDa) and P.edulis (17.50KDa) support their interspecific variation. Dendrogram based on UPGMA analysis emphasize the relationships among the taxa.

“…In this study, the basic chromosome number in the CAG, NCG, and DZG accessions was x = 8. Kazem et al (2010) and Lin et al (1999) confirmed that P. armeniaca was 2n = 2x = 16. Apricot genotypes have a common karyotype pattern, including the presence of m and sm, and the chromosome length is approximately the same (Lv, 1986).…”

“…Geographically, cultivated apricot trees in the southern Tianshan Mountains of Xinjiang (CAG) most likely evolved from the spread of wild apricot trees in the Ili Valley (DZG). Information on differences in chromosome number and karyotypic characteristics between wild and cultivated species can be used as an important tool in fruit tree heredity and breeding (Kazem et al, 2010). Furthermore, wild species can provide an abundance of germplasm resources for improved breeding selections or lines (Kazem et al, 2010).…”

The present study aims to reveal the karyotypic characteristics and genetic relationships of apricot (Prunus armeniaca L.) accessions from different ecological groups. Fourteen, 9, and 30 accessions from the Central Asian ecological group, North China ecological group, and Dzhungar-Ili ecological group, respectively, were analyzed according to the conventional pressing plate method. The results showed that all the apricot accessions from the different ecological groups were diploid (2n = 2x = 16). The total haploid length of the chromosome set of the selected accessions ranged from 8.11 to 12.75 μm, which was a small chromosome, and no satellite chromosomes were detected. All accessions had different numbers of median-centromere chromosomes or sub-median-centromere chromosomes. The karyotypes of the selected accessions were classified as 1A or 2A. Principal component analysis revealed that the long-arm/short-arm ratio (0.968) and the karyotype symmetry index (−0.979) were the most valuable parameters, and cluster analysis revealed that the accessions from the Central Asian ecological group and Dzhungar-Ili ecological group clustered together. In terms of karyotypic characteristics, the accessions from the Dzhungar-Ili ecological group and Central Asian ecological group were closely related.
