Abstract

ROS signaling and its involvement in abiotic stress with emphasis on heat stress-driven anther sterility in plants, Crop and Environment, https://doi. Abstract 12 With global warming, crop plants are challenged by heat stress during reproductive growth, 13 leading to male sterility and yield reduction. The balance between reactive oxygen species (ROS) 14 generation and scavenging is disrupted by stress, resulting in oxidative stress, which is harmful to 15 crop growth. However, recent advances have shown that ROS signaling via proteins that sense the 16 redox state is positive for plant performance under stress. ROS signaling is also involved in 17 regulating anther development, such as timely tapetum degeneration. We summarize recent progress 18 in uncovering the mechanism of heat stress effects on ROS homeostasis and discuss the relationship 19 between oxidative stress and metabolic disorder, which is often observed during anther development 20 under heat stress. We propose experimental and breeding strategies to improve field crop tolerance 21 to heat stress. 22
