• Here, we have examined a long sterile lemma1 (g1) mutant, in which the sterile lemma is enlarged like the lemma
• Detailed phenotypic analysis reveals that the large sterile lemma in the g1 mutant appears to be caused by homeotic transformation of the sterile lemma into a lemma, suggesting that G1 is involved in the repression of lemma identity to specify the sterile lemma
• G1 mRNA is expressed in sterile lemma primordia throughout their development, and G1 protein is localized in the nucleus
• We also show that a wild rice species, Oryza grandiglumis, that forms large sterile lemmas has serious mutations in the G1 gene
• The homeotic gene long sterile lemma (G1) specifies sterile lemma identity in the rice spikelet
• Repression of lemma identity by G1 is consistent with a hypothesis proposed to explain the morphological evolution of rice spikelets
• Generally, our findings provided valuable information for better understanding functions of G1 and OsLHS1 in flower development and identities of empty glumes

• BLS1~BSG1~OsG1L6~TH1~AFD1, G1, A role for TRIANGULAR HULL1 in fine-tuning spikelet morphogenesis in rice., We then examined the effect of th1 mutation on the lemma-like structure formed in the long sterile lemma/glume1 (g1) and extra glume1 (eg1) mutants
• BLS1~BSG1~OsG1L6~TH1~AFD1, G1, A role for TRIANGULAR HULL1 in fine-tuning spikelet morphogenesis in rice., The result showed that the th1 mutation strongly affected the morphology of the extra lemma of eg1, but had no significant effect on the transformed lemma of g1
• G1, OsCDC48, OsCDC48/48E complex is required for plant survival in rice Oryza sativa L.., Removal of the C-terminus of OsCDC48 caused altered expression of cell cycle-related genes, changed the percentage of cells in G1 and G2/M phases, and abolished the interaction between OsCDC48 itself and between OsCDC48 and OsCDC48E, respectively
• G1, OsCDC48E, OsCDC48/48E complex is required for plant survival in rice Oryza sativa L.., Removal of the C-terminus of OsCDC48 caused altered expression of cell cycle-related genes, changed the percentage of cells in G1 and G2/M phases, and abolished the interaction between OsCDC48 itself and between OsCDC48 and OsCDC48E, respectively
• G1, pds1, The rice pds1 locus genetically interacts with partner to cause panicle exsertion defects and ectopic tillers in spikelets., qPCR analysis revealed that Loc_Os080595 might be the target of pds1 locus, and G1 gene might be involved in the genetic mechanism underlying the pds phenotype
