Annotated Information
Gene Symbol
- Os03g0300000 <=> OsXXT1,XXT1,SRH2,OsSRH2
Function
- OsXXT1 in maintaining cell wall structure and tensile strength in rice, a typical grass species that contains relatively low XyG content in cell walls.
Phenotypic analysis
- Seeds from the M 2 generation of an EMS-mutagenized population of Indica cultivar Kasalath, were germinated and grown in nutrient solution to screen for mutants with abnormal root hair phenotype. Seven days after germination, a mutant with significantly reduced length in root hairs was
identified (Fig. 1A, B). No obvious difference was observed in leaf or root growth between wild type and mutant (Fig. S1).
- The mutant was designated as srh2. Scanning electron microscopy of the wild-type and srh2 root surface showed that the length of the root hairs of srh2 were shorter than those of wild type.
- However, no significant difference was found in root hair density or distribution pattern between srh2 and wild type (Fig. 1D, E).
Expression
- OsXXT1 and OsGT2 have similar expression patterns and are expressed across a variety of tissues. In contrast, other members of this family (OsGT3 to OSGT5) display a more restricted expression pattern, suggesting that OsXXT1 and OsGT2 are the predominantly expressed genes.
Evolution
- OsXXT1 displays more than 70% amino acid sequence identity with the previously characterized Arabidopsis thaliana XYG XYLOSYL TRANSFERASE 1 (AtXXT1) and XYG XYLOSYL TRANSFERASE 2 (AtXXT2), which catalyse the transfer of xylose onto β-1,4-glucan chains.
You can also add sub-section(s) at will.
