Abstract excerpt
Programmed cell death (PCD) during tapetum degeneration in postmeiotic anthers is critical for the proper development of male gametophytes in flowering plants. Although several genes involved in this process have been identified recently, the molecular mechanism is still poorly understood. Here, we show that knockout of rice (Oryza sativa) APOPTOSIS INHIBITOR5 (API5), which encodes a putative homolog of...
