Micronutrient metabolism in chickpea, Hydroponics, Microbial Biotechnology and Metagenomics for microbial characterisation.

Research achievements
  • Transformation of a native cry2AC gene in tobacco and verification of protein expression in transgenic plants.
  • Molecular characterisation of a cryptic promoter isolated from Arabidopsis thaliana identification of bidirectionality of the promoter and verification of its expression in heterologous systems through transient biolistic transformation and Agrobacterium mediated stable transformation in Brassica juncea
  • Elucidating molecular mechanisms of sex expression in castor. Identified the stage of sex determination and floral developmental stages through histological and SEM studies, conducted cytogenetic and epigenetic studies on sex mechanisms and identified few differentially expressed genes involved in sex determination in castor.
  • Developed culture media for in vitro sporulation of gray mold of castor, identified for the first time the isolate in Hyderabad as Amphobotrys ricini through ITS sequencing and development of a screening method for gray mold under artificial epiphytotic conditions.
  • Currently working on decoding the molecular mechanisms governing molybdenum and boron metabolism in Chickpea (Cicer arietinum L) under acidic soil conditions.
