Oxytenanthera abyssinica (A. Rich.) Munro; lowland bamboo (Poaceae, Bambusinea) in Ethiopia: Genetic diversity, population structure and gene flow analysis

As one of the most important non-timber forest resources, a potential alternative to wood and wood product and fastest-growing plant in the world (91 cm (35 in) per day), bamboo is a member of the grass family (Poaceae) and constitutes a single subfamily Bambusoideae. 67% of total area of bamboo in Africa and 7% of world total is contributed by Ethiopia giving more than 1.44 million hectares. Silica gel dried young fresh leaves from 130 individuals of O. abyssinica were collected for DNA extraction and PCR amplification. Each of the PCR amplified ISSR fragments using 19 ISSR primers were used to study band pattern and heterozigosity, level of polymorphism, calculating marker efficiency, Nei`s (H) and Shannon (I) genetic diversity, analysis of molecular variance (AMOVA), analysis for cluster, principal coordinates (PCoA) and admixture results. High genetic variation at species level was observed with the percentage of the polymorphic loci (PPL) = 84.48%. The H, I, observed number of alle...
