Os02g0671100

The rice Os02g0671100 was reported as MAIF1 in 2011 by researchers from China.

Annotated Information

Function

• The rice MAIF1 encodes a protein with a F-box domain.
• Growth restraint in plants is an acclimatization strategy against abiotic stress.
• MAIF1 is involved in multiple signaling pathways in regulating root growth.
• MAIF1 plays the negative role in response to abiotic stress possibly by regulating root growth.

Expression

• MAIF1 expression is induced rapidly and strongly by abscisic acid (ABA) and abiotic stresses.
• MAIF1 expression is also induced in root tips by sucrose, independent of its hy-drolytic hexose products, glucose and fructose, and the plant hormones auxin and cytokinin.

Phenotypic analysis

• Overexpression of MAIF1 reduces rice ABA sensitivity and abiotic stress tolerance and promotes rice root growth.

Subcellular localization

• The MAIF1 protein is mainly localized in the plasma membrane and nucleus.
