  • Ph.D Thesis: “Molecular Genetic analysis of Trichome Development in Arabidopsis thaliana” under the supervision of Dr. Utpal Nath, Department of Microbiology and Cell Biology, Indian Institute of Science, Bangalore, India.

The objective of my thesis is to study how cells acquire a specific shape and I chose the specialized epidermal cell, trichome, to address this question in Arabidopsis thaliana. By analyzing the leaf/stem trichomes in a series of loss and gain-of-function lines of class II TCP genes, I have shown that these transcription factors inhibit both the density as well as branching of Arabidopsis trichomes. By a series of biochemical and transgenic experiments, I have found that TCP4 reduces trichome branching by directly activating GLABROUS INFLORESCENCE STEMS and inhibits trichome initiation by directly promoting TRICHOMELESS1 and 2. Thus, these results demonstrate that the class II TCP genes not only suppress the proliferation of the leaf pavement cells in early leaf development, they also regulate the differentiation of the specialized epidermal cells such as trichomes later in leaf development.

I also studied the role of the deubiquitinase named AtUBP14/TARANI, which was earlier studied in our lab (Karidas et al., 2015). In a tarani loss of function mutant, the trichomes are hyper-branched. By performing genetic interaction studies with other trichome mutants, I have shown that TARANI suppresses trichome branching independent of the other identified molecules such as KAKTUS, and dependent of the BRANCHLESS TRICHOMES (BLT) protein, which is necessary for the trichome branching. TNI does not alter the level of BLT transcript, and possibly regulates its protein product. By over-expressing and down-regulating TNI (through RNA interference) specifically in the trichome cells, I have demonstrated that a balanced amount of TNI is required for normal trichome development; both increase and decrease of TNI protein leads to hyper-branched trichomes.

  • M.Sc. Dissertation: “Biochemical and Phenotypic Characterization of Natural Accessions in Tomato” under the supervision of Prof. R. P. Sharma, Department of Plant Sciences, University of Hyderabad, India.

My M.Sc. dissertation focused on the characterization of morphological traits (plant height, leaf architecture, inflorescence, flower and fruit morphology) and biochemical parameters (carotenoid estimation, pH etc) in a collection of natural accessions of tomato. I also performed SNP analysis of the PhyB1 gene in the natural accessions by Eco-TILLING process.
