- Genbank accession number
- Key message
- FH5/RMD is ubiquitously expressed in rice tissues, and its protein localization to the chloroplast surface is mediated by the PTEN domain
- The rmd mutants display a bending growth pattern in seedlings, are stunted as adult plants, and have aberrant inflorescence (panicle) and seed shape
- Cytological observation indicated that the growth defects of bui1 were caused mainly by inhibition of cell expansion
- The bui1 mutant displayed pleiotropic phenotypes, including bent uppermost internode, dwarfism, wavy panicle rachis, and enhanced gravitropic response
- Cytological analysis showed that rmd mutants have severe cell elongation defects and abnormal microtubule and microfilament arrays
- Connection
- OsARF24, FH5~RMD~BUI1, Rice actin-binding protein RMD is a key link in the auxin-actin regulatory loop that controls cell growth, Moreover, RMD expression is directly regulated by heterodimerized O. sativa auxin response factor 23 (OsARF23) and OsARF24, providing evidence that auxin modulates the orientation of F-actin arrays through RMD.
- OsARF24, FH5~RMD~BUI1, Rice actin-binding protein RMD is a key link in the auxin-actin regulatory loop that controls cell growth, In support of this regulatory loop, osarf23 and lines with reduced expression of both OsARF23 and OsARF24 display reduced RMD expression, disrupted F-actin organization and cell growth, less sensitivity to auxin response, and altered auxin distribution and OsPIN localization.
