Abstract excerpt
In higher plants, both normal meiosis and timely degradation of tapetal cells are crucial for gametophyte development, and abnormal reactive oxygen species (ROS) levels are detrimental to this process. However, the molecular mechanisms underlying their coordination remain unclear. Here, we isolated and characterized a sterile rice mutant, designated as abnormal meiocytes and tapetum 1 (Osamt1). Compared with the...
