Project description:Ziziphus nummularia is well distributed in the Thar desert encompassing India and Pakistan. It survives in regions with an average annual rainfall lesser than 100 mm. Transcriptome profiling was done in Z. nummularia genotype CIAHZN-J under control and drought-stress at -0.3MPa. Among the unique transcripts identified, 283 were found to be downregulated and 554 upregulated in comparison to control. The important down-regulated transcripts identified were: LRR receptor like serine/threonine protein kinases, oligo peptide transporter OPT family, myrcene synthase, LRR protein kinase family isoform1, ATP binding cassette transporter, phytochrome kinase, Pectin estrase inhibitor like-35, auxin efflux facilitator isoform 1, multidrug resistance protein, pectin methyl esterase 3 and ABC transporter B family. Similarly some of the upregulated transcripts are: Raffinose synthase family protein, wall associated receptor kinase like, acyl transferase like protein, cadmium/zinc transporting ATPase 3 like, sucrose synthase 6-like, cytochrome P-450 like, phosphatase 2C family protein and TT12-2 MATE transporter. This study will be very useful to identify novel genes that may be involved in drought tolerance of Z. nummularia.
