Abstrakt: | OsGBPs are a small family of four genes in rice (Oryza sativa L.) that function as transcription factors recognizing the GAGA motif; however, their functions in plant growth and development remain unclear. Here we report the functions of OsGBPs in plant growth and grain development. Knock-down and knock-out of OsGBP1 promoted seedling growth and enhanced grain length, whereas overexpression of OsGBP1 exhibited the opposite effect on seedling growth and grain length, indicating that OsGBP1 repressed grain length and seedling growth. In addition, overexpression of OsGBP1 led to delayed flowering time and suppressed plant height. OsGBP1 could regulate OsLFL1 expression through binding to the (GA) (© 2018 The Authors The Plant Journal © 2018 John Wiley & Sons Ltd.) |
