Os05g0588500
From RiceWiki
- Os05g0588500, also named OsSWEET5, is a member of SWEETs, a MtN3 and saliva related transmembrane protein family[1][2].
Annotated Information
Function
- OsSWEET5 encodes a sugar transporter protein involved in galactose transport[3].
- Overexpression of OsSWEET5 causes growth retardation, precocious senescence, galactose accumulation and disordered sugar distribution, results in the inhibition of auxin signaling and translocation[4][5][6].
- Knockout of OsSWEET5 causes no obvious phenotypes.
Expression Pattern
- OsSWEET5 was mainly expressed in the floral organs at the heading stage, and was also detectable in stem, root and senescing leaves.
Subcellular Localization
- OsSWEET5 encoded a plasma membrane protein.
