• Information
  • Symbol: RTS
  • MSU: LOC_Os01g70440
  • RAPdb: Os01g0929600
• Publication
  • RTS, a rice anther-specific gene is required for male fertility and its promoter sequence directs tissue-specific gene expression in different plant species, 2006, Plant Mol Biol.
• Genbank accession number
  • U12171
• Key message
  • Light and near-infrared confocal microscopy of cross-sections through developing flowers of male-sterile transgenics shows that tissue-specific expression of barnase or the antisense RTS genes interrupts tapetal development, resulting in deformed non-viable pollen
  • These results demonstrate a critical role of the RTS gene in pollen development in rice and the versatile application of the RTS gene promoter in directing anther-specific gene expression in both monocotyledonous and dicotyledonous plants, pointing to a potential for exploiting this gene and its promoter for engineering male sterility for hybrid production of various plant species
  • A tapetum-specific gene, RTS, has been isolated by differential screening of a cDNA library from rice panicles
  • Transgenic and antisense RNA approaches revealed that RTS gene is required for male fertility in rice
  • RTS, a rice anther-specific gene is required for male fertility and its promoter sequence directs tissue-specific gene expression in different plant species
  • Several other sequence motifs found in other anther-specific promoters were also identified in the promoter of the RTS gene
