Gene Details:

• MSU gene ID: LOC_Os10g42750
• RAPdb gene ID: Os10g0578200
• Gene Symbol: OsCSLD1 rth-2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here we show that the Oryza sativa cellulose synthase-like D1 (OsCSLD1) gene is required for root hair development, as rice (Oryza sativa) mutants that lack OsCSLD1 function develop abnormal root hairs.
• Because the csld1 mutants develop the same density and number of root hairs along their seminal root as the wild-type plants, we propose that OsCSLD1 function is required for hair elongation but not initiation.
• Both gene trap expression pattern and in situ hybridization analyses indicate that OsCSLD1 is expressed in only root hair cells.
• Given that the Arabidopsis (Arabidopsis thaliana) gene KOJAK/AtCSLD3 is required for root hair elongation and is expressed in the root hair, it appears that OsCSLD1 may be the functional ortholog of KOJAK/AtCSLD3 and that these two genes represent the root hair-specific members of this family of proteins.
• OsCSLD1, a cellulose synthase-like D1 gene, is required for root hair morphogenesis in rice.
• In situ hybridization showed that OsCSLD1 was expressed not only in root hairs but also in epidermal and cortex cell walls except for stele.
• qRT-PCR analysis revealed that OsCSLD1 was expressed not only in root but also in shoot.
• Root hairless 2 (rth2) mutant represents a loss-of-function allele of the cellulose synthase-like gene OsCSLD1 in rice (Oryza sativa L.).
• Positional cloning and complementation test revealed that the causal gene of rth2 was Cellulose Synthase-Like D1 (OsCSLD1).
• Furthermore, OsCSLD1 is the only member of the four rice CSLD genes that shows root-specific expression.
• OsCSLD1 Mediates NH(4)(+)-Dependent Root Hair Growth Suppression and AMT1;2 Expression in Rice (Oryza sativa L.).
