  • Small and round seed 5 gene encodes alpha-tubulin regulating seed cell elongation in rice, 2012, Rice (N Y).
  • A dominant mutation of TWISTED DWARF 1 encoding an α-tubulin protein causes severe dwarfism and right helical growth in rice, 2009, Genes Genet Syst.
• Genbank accession number
  • AK102560
• Key message
  • Our analysis of the Tid1-1 mutant revealed that the dynamics of microtubules affects not only anisotropic growth in both dicots and monocots, but also meristematic activity and gross plant morphology
  • Here, we report a dominant mutant, Twisted dwarf 1-1 (Tid1-1), showing dwarfism and twisted growth in rice
  • Tid1-1 exhibit right helical growth of the leaves and stem and shortening of the roots
  • These data indicate that SRS5 independently regulates cell elongation of the brassinosteroid signal transduction pathway
  • In this study, we report a novel semi-dominant mutant Small and round seed 5 (Srs5) that encodes alpha-tubulin protein
  • Seeds of the double mutant of Srs5 and d61-2 were smaller than those of Srs5 or d61-2
  • Lemma cell length was reduced in Srs5 compared with that of the wild-type
  • Cells in the leaves of Tid1-1 are often ill-shapen, possibly owing to irregular cell division
• Connection
  • D61~OsBRI1, TID1~SRS5, Small and round seed 5 gene encodes alpha-tubulin regulating seed cell elongation in rice, Seeds of the double mutant of Srs5 and d61-2 were smaller than those of Srs5 or d61-2
  • D61~OsBRI1, TID1~SRS5, Small and round seed 5 gene encodes alpha-tubulin regulating seed cell elongation in rice, Furthermore, SRS5 and BRI1 genes were highly expressed in Srs5 and d61-2 mutants
