Gene Details:

• MSU gene ID: LOC_Os04g48760
• RAPdb gene ID: Os04g0576900
• Gene Symbol: XIAO
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here we identified a rice 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 co-expression of XIAO with a number of genes involved in cell cycling.
• XIAO is involved in the control of organ size by contributing to the regulation of signaling and homeostasis of brassinosteroids and cell cycling in rice.
• The XIAO mutant displayed a tissue-specific enhanced BR response and greatly reduced BR contents at the whole-plant level.
• These results indicated that XIAO is a regulator of BR signaling and cell division.
• Thus, XIAO may provide a possible connection between BRs and cell-cycle regulation in controlling organ growth.
