Annotated Information
Gene Symbol
- Os07g0139300 <=> g1 (lng), lng, g1, ELE
Function
- G1 is a member of a plant-specific gene family that encodes proteins with a previously uncharacterized domain, named here ALOG (Arabidopsis LSH1 and Oryza G1).
- G1 is involved in the repression of lemma identity to specify the sterile lemma.
- A trans-activation assay using the yeast GAL4 system suggests that G1 is involved in transcriptional regulation. Repression of lemma identity by G1 is consistent with a hypothesis proposed to explain the morphological evolution of rice spikelets.
Mutation
- long sterile lemma1 (g1) mutant shows enlarged sterile lemma like the lemma.
Expression
- G1 mRNA is expressed in sterile lemma primordia throughout their development, and G1 protein is localized in the nucleus.
Evolution
