Seed development is a complex biological process that is controlled by various genetic and external factors, and significantly affects the seed vigor, yield and quality of crops, especially cereal plant crops. Abscisic acid (ABA) is one of the most important phytohormones that regulate seed development and germination, and plays a key role in regulation of seed development through its activity level, signaling, and LAFL network, including embryogenesis and maturation process. In recent years, important progresses have been acquired in the research of seed development regulated by ABA. In the present paper, we have mainly reviewed the research achievements in this field, including the regulation of ABA metabolism and signaling on seed development, the action between ABA and transcription factors of seed maturation (AFL-B3, FUS3, ABI3, LEC2, etc.), and the action mechanism of ABA in seed development. In addition, we also propose some scientific questions that need to be further investigated in this field to provide some information for deeply understanding the molecular mechanism of seed development, so as to improve seed vigor and increasing yield and quality. |
