Annotated Information
Function
The MOC1 gene plays an important role in the control of rice tillering, encoding a putative GRAS family nuclear protein that is expressed mainly in the axillary buds and functions to initiate axillary buds and to promote their outgrowth[1][2]. In the case of the rice plant, more tillering equates to more grain-bearing branches, hence a higher grain yield. Besides, as an member of the plant-specific GRAS family proteins that function in diverse aspects of plant development, including signal transduction, meristem maintenance and development[3][4], and as transcription factors [5], MOC1 might also function as a transcription factor[1]. MOC1 is highly homologous with the tomato Lateral suppressor (Ls) gene[1]. Ls loss-of-function mutations cause a branchless phenotype owing to a failure in axillary meristem initiation[6]. These results suggest that both Ls and MOC1 function as positive regulators of lateral branching.
=Expression
To identify genes involved in the control of rice tillering, Li et al. have screened for mutants with altered tiller numbers from collections derived from spontaneous mutations or g-ray radiation and ethyl methanesulphonate (EMS) mutagenesis, and they found that moc1 plants nearly completely lose their tillering ability after a spontaneous moc1 mutant, producing only one main culm, in contrast to the multiple tillers in wild-type plants[1]. They amplified the corresponding ORF from moc1 and wild-type plants with polymerase chain reaction (PCR) and sequenced it. DNA sequence comparison revealed a 1.9-kb retrotransposon inserted in this ORF in the moc1 mutant. Confirmation of the retrotransposon-interrupted ORF as MOC1 was achieved by functional complementation[1]. Genetic analysis with reciprocal crosses between moc1 and wild-type plants revealed that moc1 possesses a recessive mutation in a single nuclear locus[1]. We can see the effects of moc1 mutant on rice tillering from the following picture 2.
