Unraveling The Regulatory Basis Of The Desiccation Tolerance Trait In Selaginella Lepidophylla, Madhavi Anuradha Ariyarathne Hewa Babarandhage
Dissertations and Theses
Desiccation tolerance was a crucial adaptation for plants during their transition to terrestrial environments. Some spike mosses, including S. lepidophylla, have evolved the remarkable ability to tolerate extreme desiccation, enabling survival in arid regions of the world. However, the regulatory basis of this trait remains unknown. This dissertation aims to unravel the genetic basis of desiccation tolerance in Selaginella lepidophylla and its potential for improving crop abiotic stress tolerance. To achieve this goal, three objectives were pursued. Objective 1 focused on determining the regulatory role of the SlbHLH transcription factor (TF) by overexpressing it in Arabidopsis thaliana to assess its …
