Genome sequencing and characterization of microsatellite markers of L.f.: an economically important endangered tree of Eastern Ghats, India.

L.f. (red sanders) is an endemic, endangered and economically important tree species distributed in the Eastern Ghats of Andhra Pradesh, India. This tree is well known for its blood-red coloured timber which has a high value in the international market. Due to its high timber demand, illegally logging of red sanders has resulted in fragmentation and depletion of its natural populations. Assessing the genetic diversity is a prerequisite for the identification of distinct populations of red sanders in the natural habitat for prioritizing conservation efforts. The present study has focussed on genome sequencing, identification and validation of microsatellite markers of . A total of 282,918 simple sequence repeat (SSR) loci were identified using whole genome sequence from leaf tissue. A total of 28 SSRs were selected for polymorphism analysis across the 52 individuals belonging to three populations of and identified a sum of 502 alleles with polymorphic information content of 0.83; observed heteozygosity () 0.42 and expected heterozygosity () 0.69. Genetic differentiation coefficient (F) of 0.19 (F˂0.25) which is indicating moderate genetic differentiation among the populations. Six SSRs from . and Poir. were successfully amplified in and produced 131 alleles. These newly identified SSRs are useful in detecting genetic diversity and further developing conservation strategies for .
