I am a researcher from India.I am presently working on medicinally important orchids and medicinal plants present in the Northeastern part of India which is also a part of Indo Burma mega biodiversity hot spot. I am presently engaged with their molecular characterization and also formulationof their conservation strategies to ensure their sustainable utilization.I am working under the supervision of Prof. Suman Kumaria and Prof..Pramod Tandon of Northeastern Hill University,Shillong,India.

Don) Szlach.] is an endangered medicinal orchid of the Ashtvarga group of plants in Ayurveda (Indian system of traditional medicine). Using a combination of aromatic cytokinin [meta-Topolin (mT)], plant biostimulant (chitosan), auxin [indole-3-butyric acid (IBA)], and a phenolic elicitor [phloroglucinol (PG)], plants of M. acuminata were regenerated in vitro for mass multiplication. The present research reveals the first-ever transcriptome of M. acuminata. A total of 43,111 transcripts encoding 23,951 unigenes were assembled de novo from a total of 815.02 million reads obtained from leaf and pseudobulb of in vitro raised M. acuminata. Expression analysis of genes associated with β-sitosterol and eugenol biosynthesis in leaf and pseudobulb provided vital clues for differential accumulation of metabolites in M. acuminata. Ultra-performance liquid chromatography (UPLC) confirmed higher amounts of β-sitosterol and eugenol content in th...

A total of 12 SCoT and 5 IRAP markers revealed an average of 63% genetic variability [SCoT = 63.87; IRAP = 64.95%] amongst the five species investigated. The genetic similarities were assessed using both UPGMA and Bayesian approaches which indicated identical clustering patterns at a genetic similarity level of 50%. Analysis of molecular variance (AMOVA) revealed the presence of a significant degree of genetic variability, mostly compartmentalized within the species level. Amongst the five assessed species, was the most genetically diverse representative whereas was found to be least diverse based on a comparative assessment of various population genetic parameters like Nei's gene diversity (h) and Shannon's information index (I) with an overall gene flow value greater than 1. In order to evaluate...
