Abstract: In angiosperms, DELLA proteins (DELLAs) have emerged as the master transcriptional regulators responsible for repressing all aspects of gibberellin (GA)-dependent growth and development. Previous investigations have demonstrated that DELLAs are involved in almost all processes of plant development. The evidences indicate that DELLA ex- pressed in male reproductive organs, female reproductive organs and embryos in flowering plants and play a major role in diverse key events in the process of sexual reproduction of angiosperms. Here, we try to summarize the knowledge of DELLAs concerning the structural components, characteristics, expression and function in reproductive tissues during the process of plant sexual reproduction. The problems and perspectives are also discussed.

Key words: DELLA, gibberellin, sexual plant reproduction
