• Information
  • Symbol: DSH1
  • MSU: LOC_Os06g12250
  • RAPdb: Os06g0226950
• Publication
  • A rice dihydrosphingosine C4 hydroxylase DSH1 gene, which is abundantly expressed in the stigmas, vascular cells and apical meristem, may be involved in fertility, 2007, Plant Cell Physiol.
• Genbank accession number
  • AK241878
• Key message
  • Repression of DSH1 expression by the antisense gene or RNA interference (RNAi) resulted in a severe reduction of fertility
  • A rice dihydrosphingosine C4 hydroxylase (DSH1) gene, which is abundantly expressed in the stigmas, vascular cells and apical meristem, may be involved in fertility
  • Our results indicate that the product of DSH1 may be involved in plant viability or reproductive processes, and that the phenotype of sterility is apparently caused by loss of function of DSH1 in the stigma
  • The DSH1 gene was specifically and abundantly expressed in vascular bundles and apical meristems
• Connection
  • DSH1, DSH5, DSH5, a dihydrosphingosine C4 hydroxylase gene family member, shows spatially restricted expression in rice and is lethal when expressed ectopically., Rice has two types of DSH homologs: general DSHs, namely DSH1, DSH2 and DSH4, and others that show spatial expression profiles, namely DSH3 and DSH5
