Regulation of ROS through proficient modulations of antioxidative defense system maintains the structural and functional integrity of photosynthetic apparatus and confers drought tolerance in the facultative halophyte Salvadora persica L.

Publication date: Available online 31 October 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Jaykumar Rangani, Ashok Panda, Monika Patel, Asish Kumar ParidaAbstractThe facultative halophyte Salvadora persica L. grow in arid, semiarid and saline areas. In present study, drought induced alterations in growth, ion homeostasis, photosynthesis, chlorophyll fluorescence, ROS regulation and antioxidative defense components were analyzed in S. persica with an aim to elucidate the drought tolerance mechanisms. In response to drought, significant reductions in growth, photosynthesis, and photosynthetic pigments were observed in S. persica. However, leaf relative water content (RWC %) did not change significantly. In S. persica seedlings, the growth, photosynthetic pigmen...
