“…The genus Taverniera has sixteen different species (Roskov et al, 2006). It is endemic to North-east Africa and South-west Asian countries (Naik, 1998). Licorice is used as important traditional Chinese medicine with many clinical and industrial applications like Food, Herbal medicine, cosmetics etc.…”

Taverniera cuneifolia has been described as a potent substitute of Licorice in India. It has been used as an expectorant anti-inflammatory anti-ulcer wound healing blood purifier etc. Glycyrrhizin is one of the most useful bioactive sesquiterpenoid present in this plant. The present study aim to carry out transcriptome analysis in root tissue of Taverniera cuneifolia to identify specific functional genes involved in the biosynthesis of secondary metabolites. The root transcriptome sequencing of Taverniera cuneifolia resulted in a total of ~7.29 Gb of raw data and generated 55991233 raw reads. The high quality reads were de novo assembled by Trinity assembler followed through CD-HIT resulted into 35590 Unigene transcripts with an average size of 419 bp. The unigenes were analyzed using BLAST2GO resulted in 27884 (78.35%) transcript with blast hits, 22510 (63.25%) transcript with mapping and 21066 (59.19%) transcript with annotation. Functional annotation was carried out using NCBI non-redundant and Uniprot databases resulted in the identification of 21066 (59.19%) annotated transcripts and GO assigned to 24751 (69.54%) transcripts. The gene ontology result shows maximum sequences match with Biological Processes (48%) Molecular Function (27%) and Cellular components (23%). A total of 289 metabolic enriched pathways were identified which included pathways like Sesquiterpenoid and triterpenoid pathway which were involved in synthesis of secondary metabolite Glycyrrhizin biosynthesis. The enzymes squalene monooxygenase farnesyl-diphosphate farnesyltransferase beta amyrin synthase beta-amyrin 24-hydroxylase were identified by functional annotation of transcriptome data. There were several other pathways like terpenoid backbone biosynthesis steroid biosynthesis Carotenoid biosynthesis Flavonoids biosynthesis etc. which have been reported first time from this plant. Transcription factors were predicted by comparison with Plant Transcription Factor Database and 1557 trancripts belonging to 85 trancription factor families were identified. This transcriptome analysis provided an important resource for future genomic studies in Taverniera cuneifolia.

“…On scrutiny of the relevant literature (Parkinson 1923;Hajra et al 1999;Sinha 1999;Pandey & Diwakar 2008;Singh et al 2014;Murugan et al 2016;Naik & Singh 2018 a,b;Naik et al 2019; and on critical examination the identity of plants was confirmed as Chlorophytum vestitum, Elatostema cuneatum, Ammannia auriculata, and Christisonia siamensis hitherto unreported from Andaman & Nicobar Islands. Hence, this collection is found to be an addition to angiosperm flora of Andaman Islands.…”
