OsCSLD1 Mediates NH4+-Dependent Root Hair Growth Suppression and AMT1;2 Expression in Rice

The study "OsCSLD1 Mediates NH4+-Dependent Root Hair Growth Suppression and AMT1;2 Expression in Rice (Oryza sativa L.)" investigates the role of the Cellulose synthase-like D1 (CSLD1) gene in root hair growth in rice. The researchers found that CSLD1 is crucial for root hair cell expansion, and its mutants showed successful initiation but failed to elongate in the presence of ammonium (NH4+). However, when nitrogen was depleted, these root hairs resumed elongation. The study also found that the expression of AMT1;2, a specialized ammonium transporter, increased in CSLD1 mutants. The study concludes that CSLD1 is involved in nitrogen-dependent root hair elongation and regulation of AMT1;2 expression in rice roots. The study involved multiple tests with varying sample sizes, ranging from 3 to 12.
