LSD1, EDS1 and PAD4 Conditionally Regulate Cellular Signaling Homeostasis, Photosynthesis, Water Use Efficiency and Seed Yield in Arabidopsis

ABSTRACT: There is growing evidence that for a comprehensive insight into the function of plant genes it is crucial to assess their functionalities under a wide range of conditions. In this study we examined the role of LESION SIMULATING DISEASE1 (LSD1), ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1) and PHYTOALEXIN DEFICIENT4 (PAD4) in the regulation of photosynthesis, water use efficiency (WUE), ROS/hormonal homeostasis and seed yield in Arabidopsis thaliana grown in the laboratory and in the field. We demonstrate that the LSD1 null mutant (lsd1), which is known to exhibit a runaway cell death in non-permissive conditions, proves to be more tolerant to combined drought and high-light stress than the wild type. Moreover, depending on growing conditions, it shows variations in WUE, salicylic acid and hydro
