Annotated Information

Gene Symbol

  • Os04g0576900 <=> XIAO,OsXIAO

Function

  • XIAO is predicted to encode an LRR kinase.
  • XIAO may provide a possible connection between BRs and cell-cycle regulation in controlling organ growth.

Expression

  • T-DNA insertion mutant for organ size, referred to as xiao, that displays dwarfism and erect leaves, typical BR-related phenotypes, together with reduced seed setting.
  • The small stature of the xiao mutant resulted from reduced organ sizes due to decreased cell numbers resulting from reduced cell division rate, as supported by the observed coexpression of XIAO with a number of genes involved in cell cycling.
  • The xiao mutant displayed a tissue-specific enhanced BR response and greatly reduced BR contents at the whole-plant level
