Functional Descriptions:

  • By contrast, RNA-silenced lines of OSMADS58 develop astonishing flowers that reiterate a set of floral organs, including lodicules, stamens, and carpel-like organs, suggesting that determinacy of the floral meristem is severely affected.
  • The transgenic rice expressing OSMADS58SRDX had reiterated formation of lodicule-like organs instead of stamens and carpel, a typical phenotype of ag mutant.
  • Although the transgenic tall fescue did not have the stamen alterations seen in SPW1SRDX and OSMADS58SRDX rice, they either produced no pollen or produced immature pollen; thus, the anthers were not dehiscent and the plants were male-sterile.
  • We first introduced Os12g0207000SRDX, Os01g0886200SRDX and OSMADS58SRDX into rice for evaluation of their abilities to induce male sterility.
  • We also obtained a mild phenotype of OSMADS58SRDX tall fescue, which exhibited only the male sterility.
  • Male-sterile and cleistogamous phenotypes in tall fescue induced by chimeric repressors of SUPERWOMAN1 and OSMADS58.
  • Some lines of OSMADS58SRDX tall fescue showed a cleistogamous phenotype in which the lodicules were homeotically transformed into lemma-like organs.
  • Furthermore, our results indicate important roles of OsMADS32 in defining stamen, pistil and ovule development through physical and genetic interactions with OsMADS1, OSMADS58 and OsMADS13, and in specifying floral meristem identity with OsMADS6, OsMADS3 and OSMADS58 respectively.
  • Rice (Oryza sativa) OSMADS58 is a C-class MADS box protein, and characterization of a transposon insertion mutant OSMADS58 suggested that OSMADS58 plays a role in stamen development.
  • This CRISPR mutant line exhibited stronger changes in expression of OSMADS58 target genes compared with the OSMADS58 dSpm (transposon insertion) line, along with changes in multiple pathways related to early stamen development.
  • These findings strongly suggest that the pleiotropic effects of OSMADS58 on stamen development derive from a potential role in stabilizing gene regulatory circuits during early stamen development.
  • Here, we report that the CRISPR knockout mutant OSMADS58 exhibits complex altered phenotypes, including anomalous diploid germ cells, aberrant meiosis, and delayed tapetum degeneration.
  • OSMADS58 Stabilizes Gene Regulatory Circuits during Rice Stamen Development.
