“…Unlike SSRs these markers do not require prior knowledge of genome sequence. Despite limitations regarding reproducibility of RAPD, combination of ISSR and RAPD markers has been used for understanding population genetic diversity and structure in a number of species ( Naik et al 2009 ; Ding et al . 2013 ; Harish et al .…”

Knowledge of the natural genetic variation and structure in a species is important for developing appropriate conservation strategies. We aimed to examine (i) the patterns and levels of morphological and genetic variability within/among populations of Plumbago zeylanica and ascertain whether these variations are dependent on geographical conditions; and (ii) evaluated genetic differentiation and population structure within the species. ISSR and RAPD markers were used to study the genetic structure and variation within and among populations collected from 13 widespread regions in India. High levels of genetic diversity and significantly high genetic differentiation were revealed by both the markers among all studied populations.

“…Climate and edaphic factors also modify the distribution and growth rates of species in mature tropical forests (Clark et al, 1999;Condit et al, 2002;Baker et al, 2003;Hall et al, 2004;Svenning et al, 2004). Furthermore, significant clone by site (Naik et al, 2009) or environment by genotype interactions have been observed in detailed provenance trials (Butterfield, 1996). Significant topographic effects connected to soil quality and erosion has also been found in a few restoration trials (Carpenter et al, 2004).…”

“…The coefficient of genetic differentiation among populations (Gst) was 0.1324 suggesting 13.24% variation. Madhuca is a member of the family Sapotaceae and we observed that this value was lower than that of another Sapotaceae member Argania spinose (Aabd et al 2015) and it was higher than Gmelina arborea studied from India (Naik et al 2009). Gst indicated a low level of genetic differentiation among populations.…”

“…ISSRs have been used to study genetic diversity in spatially isolated populations (Apte et al 2006;Bahulikar et al 2004a), temporal populations (Bahulikar et al 2004b), accessions of crops (Idris et al 2012;Morikawa et al 2014;Nagaraju et al 2002), etc. Dinucleotide repeats have been used very frequently than tri-or tetra-nucleotide repeats to accesses diversity of tree species (Bahulikar et al 2004a;Aabd et al 2015;Naik et al 2009;Dai et al 2013).…”

provides livelihood to several tribal people in India, where the flowers are used for extraction of sweet juices having multiple applications. Certain trees have more value as judged by the tribal people mainly based on yield and quality performance of the trees, and these trees were selected for the genetic diversity analyses. Genetic diversity of 48 candidate Mahua trees from Etapalli, Dadagaon, and Jawhar, Maharashtra, India, was assessed using ISSR markers. Fourteen ISSR primers revealed a total of 132 polymorphic bands giving overall 92% polymorphism. Genetic diversity, in terms of expected number of alleles (Ne), the observed number of alleles (Na), Nei's genetic diversity (H), and Shannon's information index () was 1.921, 1.333, 0.211, and 0.337, respectively, and suggested lower genetic diversity. Region wise analysis revealed higher genetic diversity for site Etapalli ( = 0.206) and lowest at Dhadgaon ( = 0.140). Etapalli area possesses higher forest cover than Dhadgaon and Jawhar. Additionally, in Dhadgaon and Jawhar trees are restricted to field bunds; both reasons might contribute to lower genetic diversity in these regions. The dendrogram and the principal coordinate analyses showed no region-specific clustering. The clustering patterns were supported by AMOVA where higher genetic variance was observed within trees and lower variance among regions. Long-distance dispersal and/or higher human interference might be responsible for low diversity and higher genetic variance within the candidate trees.
