- Genbank accession number
- Key message
- In addition, the Gnp4 and Lax1-1 double mutant showed dramatically reduced secondary branches and spikelets in panicle at reproductive stage, and tillers at vegetative stage
- Fine Mapping and Cloning of the Grain Number Per-Panicle Gene (Gnp4) on Chromosome 4 in Rice (Oryza sativa L.)
- LAX2 regulates the branching of the aboveground parts of a rice plant throughout plant development, except for the primary branch in the panicle
- The lax2 mutant is similar to lax panicle1 (lax1) in that it lacks an AM in most of the lateral branching of the panicle and has a reduced number of AMs at the vegetative stage
- The lax1 lax2 double mutant synergistically enhances the reduced-branching phenotype, indicating the presence of multiple pathways for branching
- In this study, we identified a natural mutant, gnp4, lack of lateral spikelet on the secondary branches in the field condition
- Here, we characterized the rice (Oryza sativa) lax panicle2 (lax2) mutant, which has altered AM formation
- Connection
- Gnp4~LAX2, LAX1, LAX PANICLE2 of rice encodes a novel nuclear protein and regulates the formation of axillary meristems, The lax2 mutant is similar to lax panicle1 (lax1) in that it lacks an AM in most of the lateral branching of the panicle and has a reduced number of AMs at the vegetative stage
- Gnp4~LAX2, LAX1, LAX PANICLE2 of rice encodes a novel nuclear protein and regulates the formation of axillary meristems, The lax1 lax2 double mutant synergistically enhances the reduced-branching phenotype, indicating the presence of multiple pathways for branching
- Gnp4~LAX2, LAX1, LAX PANICLE2 of rice encodes a novel nuclear protein and regulates the formation of axillary meristems, LAX2 encodes a nuclear protein that contains a plant-specific conserved domain and physically interacts with LAX1
- Gnp4~LAX2, LAX1, LAX PANICLE2 of rice encodes a novel nuclear protein and regulates the formation of axillary meristems, We propose that LAX2 is a novel factor that acts together with LAX1 in rice to regulate the process of AM formation
- FZP~BFL1~SGDP7~PAA7, Gnp4~LAX2, Panicle Apical Abortion 7 Regulates Panicle Development in Rice Oryza sativa L.., Moreover, the severe damage for panicle phenotype in paa7/lax2 double mutant indicated that PAA7 could crosstalk with Lax Panicle 2 (LAX2)
- FZP~BFL1~SGDP7~PAA7, Gnp4~LAX2, Panicle Apical Abortion 7 Regulates Panicle Development in Rice Oryza sativa L.., These findings suggest that PAA7 regulates the development of apical spikelets and interacts with LAX2 to regulate panicle development in rice
