“…These results agreed with those of Casiva et al (2002) who studied the genetic diversity among four Argentinean Acacia species with seven isozyme systems and detected 21 loci showing high genetic variability that allowed them to differentiate the species. On the other hand, the seventeen unique bands recorded in the present study were observed in all isozyme patterns that could be considered as biochemical markers for Acacia species.…”

“…Because of their validity and simplicity; biochemical protein markers (SDS-PAGE and isozymes) are still efficient tools used to address the interspecific and intraspecific diversity and are considered to be more accurate than those of traditional methods for authentication and discrimination among Acacia species (Casiva et al, 2002;Shukor et al, 2006 andKarakish et al, 2013).…”

LTHOUGH their wide distribution in arid lands and their many uses that include fodder and fuel besides the environmental values of soil stabilization, Acacia species are vulnerable to elimination in Saudi Arabia. In this study, seed morphology and patterns of their coat surface sculpture as revealed by scanning electron microscopy besides both seed proteins and seven isozymes profiles were employed for the discrimination and authentication the vulnerable Saudi Arabian Acacia collected from the western region of the kingdom. The scanning electron microscopic study displayed diversity in shape, dimensions, color, central aerole features and coat topography of seeds among different species to be characteristic for each species. Seed protein and isozyme profiles showed high variability among studied species. The UPGMA phenogram and genetic similarity analysis based on combination of seed morphology, protein and isozyme patterns confirmed the extensive genetic diversity existed in Acacia species.

“…Camellia reticulata is distributed from Yunnan to Sichuan Provinces in the southwest of China, and its distribution is wider than that of most Camellia species (Ming, 1998). Species with wider distribution tended to be more genetically diverse (Casiva et al, 2002). There are 3 cell ploidies in C. reticulata, and some polyploidy populations have been shown to originate through hybridization (Hamrick and Godt, 1996).…”

ABSTRACT. Camellia reticulata is a well-known ornamental and oil plant that is endemic to southwest China. This species shows three cell ploidies, i.e., diploidy, tetraploidy and hexaploidy. We made the first investigation of genetic diversity and differentiation of natural populations of C. reticulata, and 114 individuals from 6 populations were sampled. Cytogeography results showed that ploidy is invariable within populations and evenly distributed. A relatively high level of genetic diversity was found in C. reticulata, both at the species level (PPB = 88.89%; H = 0.2809; I = 0.4278) and at the population level (mean PPB = 42.13%; mean H = 0.14; mean I = 0.21). We found a relatively low degree of differentiation among ploidies (G ST = 0.2384; AMOVA = 10.26%) and a relatively high degree of differentiation among populations (G CS = 0.3807; AMOVA = 48.75%). The high genetic diversity can be explained by its biological char acter, wide distribution and ploidies, and the special genetic structure can be ascribed to polyploid origin from hybridization with different Camellia spp. This information will be useful for the introduction, conservation and further studies of C. reticulata and related species.

RAPD Variation Among North Vietnamese Flemingia macrophylla (Willd.) Kuntze ex Merr. accessions

2006

Flemingia macrophylla (Willd.) Kuntze ex Merr., a multi-purpose legume with potential as dry-season forage crop, mainly occurs in subhumid to humid environments of tropical and subtropical Asia. Despite increasing interest in conservation of germplasm suitable for low-input production systems information on the genetic diversity of F. macrophylla is extremely scarce. The creation of baseline data is supposed to contribute to more efficient conservation management and to identify collecting strategies of novel germplasm. Random amplified polymorphic (RAPD) markers were used to investigate the genetic variation among 37 F. macrophylla accessions. Germplasm analysed in this study originated from Bac Kan province, Northeast Vietnam. Eight primers generated a total of 47 amplified RAPD loci of which 38 were polymorphic. Jaccard's similarity coefficients among accessions ranged from 0.069 to 1 with a mean of 0.67. The UPGMA dendrogram revealed three clusters along with three outliers. No correspondence between geographic and genetic distance was found (Mantel test: R = 0.21; P = 0.016). Analysis of molecular variance (AMOVA) revealed significant (P < 0.001) differentiation between accessions collected in lowland and upland regions. Results of UPGMA clustering were confirmed by the pattern of principle coordinates analysis (PCO) plotting. Future collecting strategies should target populations at large distances and along the altitudinal range. Ex situ conservation should encompass those accessions that showed genetic divergence. In situ conservation may consist of establishing a system of interconnected population fragments to guarantee continuing genetic exchange via corridors and of rehabilitating degraded habitats.
