- 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
- In this study, we showed that overexpression of SRS5 can promote grain length and demonstrated that the overexpression of SRS5 in BR-related mutants rescued the shortened grain length, which is an unfavorable phenotype in the yield potential of BR-related mutants, while preserving the useful semi-dwarf and erect leaf phenotypes
- Overexpression of SRS5 improves grain size of brassinosteroid-related dwarf mutants in rice (Oryza sativa L.).

- Overexpression of SRS5 improves grain size of brassinosteroid-related dwarf mutants in rice ( Oryza sativa L.)
- Previously, we cloned SMALL AND ROUND SEED 5 (SRS5) gene (encoding alpha-tubulin) from a small and round seed mutant and revealed that this gene regulates grain length independently of the brassinosteroid (BR) signaling pathway, although BR-related mutants set small grain.
