• Key message
  • 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
• Connection
  • OSMADS3, OSMADS58, Functional diversification of the two C-class MADS box genes OSMADS3 and OSMADS58 in Oryza sativa, To examine the conservation and diversification of C-class gene function in monocots, we analyzed two C-class genes in rice (Oryza sativa), OSMADS3 and OSMADS58, which may have arisen by gene duplication before divergence of rice and maize (Zea mays)
  • OSMADS3, OSMADS58, Functional diversification of the two C-class MADS box genes OSMADS3 and OSMADS58 in Oryza sativa, , the functions regulated by AG have been partially partitioned into two paralogous genes, OSMADS3 and OSMADS58, which were produced by a recent gene duplication event in plant evolution)

  • CCP1~DFO1~EMF1, OSMADS58, CURVED CHIMERIC PALEA 1 encoding an EMF1-like protein maintains epigenetic repression of OsMADS58 in rice palea development., We found that OsMADS58, a C-class gene responsible for carpel morphogenesis, was ectopically expressed in the ccp1palea, indicating that the ccp1 palea was misspecified and partially acquired carpel-like identity
  • CCP1~DFO1~EMF1, OSMADS58, CURVED CHIMERIC PALEA 1 encoding an EMF1-like protein maintains epigenetic repression of OsMADS58 in rice palea development., Constitutive expression of OsMADS58 in the wild-type rice plants caused morphological abnormality of palea similar to that of ccp1, whereas OsMADS58 knockdown by RNAi in ccp1 could rescue the abnormal phenotype of mutant palea, suggesting that the repression of OsMADS58 expression by CCP1 is critical for palea development
  • CCP1~DFO1~EMF1, OSMADS58, CURVED CHIMERIC PALEA 1 encoding an EMF1-like protein maintains epigenetic repression of OsMADS58 in rice palea development., Taken together, our results show that CCP1 plays an important role in palea development through maintaining H3K27me3-mediated epigenetic silence of the carpel identity-specifying gene OsMADS58, shedding light on the epigenetic mechanism in floral organ development
  • OsMADS1~LHS1~AFO, OSMADS58, Interactions of OsMADS1 with Floral Homeotic Genes in Rice Flower Development., The physical and genetic interaction of OsMADS1 and OsMADS3 is essential for floral meristem activity maintenance and organ identity specification; while OsMADS1 physically and genetically interacts with OsMADS58 in regulating floral meristem determinacy and suppressing spikelet meristem reversion
