Abiotic stresses are the primary cause of crop failure worldwide, reducing yields by sometimes more than 50%. Among the various forms of abiotic stress, drought or water stress is the most limiting factor for rice productivity.
Drought affects about 20% of the total rice cultivation area in Asia. Understanding the various aspects of drought stress and the response and resistance mechanisms in plants is therefore of fundamental importance to improve sustainable agriculture. The overall objective of the work presented in this thesis was to get more detailed insight in the molecular regulation of drought tolerance in rice, with a particular focus on the role of drought-responsive transcription factors and two groups of plant hormones, abscisic acid and strigolactones.
