      Research Interests

      • My main research interest is on light and abiotic stress signaling pathway and developemnt of transgenic plants.   During my postdoc, I studied a group of Arabidopsis proteins (STO, STH, STH2 & STH3) that were identified through their interactions with two key regulators of light signaling, COP1 and HY5. Also The Arabidopsis plants with mutations in the STH2 gene showed hypersensitivity to Abscisic acid (ABA), a drought and salt stress regulating hormone, and to NaCl in germination and root growth assay. Furthermore, the expression of several key regulators of ABA signaling was altered in the sth2 mutant indicating that the STH2 gene plays an important role in response to drought and salinity. Hence, applying this knowledge gained from  Arabidospsis on rice could be  a worth effort to obtain drought and salinity  tolerance Sri Lankan rice varieties.
