Gene Details:

Functional Descriptions:

  • Cytokinin oxidase/dehydrogenase OsCKX11 coordinates source and sink relationship in rice by simultaneous regulation of leaf senescence and grain number.
  • ) cytokinin oxidase/dehydrogenase OsCKX11 in delaying leaf senescence, increasing grain number, and coordinately regulating source and sink.
  • OsCKX11 was predominantly expressed in the roots, leaves, and panicles and was strongly induced by abscisic acid and leaf senescence.
  • Thus, OsCKX11 functions antagonistically between cytokinins and ABA in leaf senescence.
  • Collectively, our findings reveal that OsCKX11 simultaneously regulates photosynthesis and grain number, which may provide new insights into leaf senescence and crop molecular breeding.
  • Moreover, OsCKX11 presented with significantly increased branch, tiller, and grain number compared with the WT.
  • In the OsCKX11 mutant, the ABA-biosynthesizing genes were down-regulated and the ABA-degrading genes were up-regulated, thereby reducing the ABA levels relative to the WT.
  • Cytokinin levels were significantly increased in the flag leaves of OsCKX11 mutant compared to those of the wild type (WT).
