Gene Details:

• MSU gene ID: LOC_Os07g49330
• RAPdb gene ID: Os07g0694000
• Gene Symbol: OsPLC1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Salt stress induced the recruitment of OsPLC1 from cytoplasm to plasma membrane, where it hydrolyzed PtdIns4P.
• In addition, the enlargement of grain size was observed in OE plants, however, the reduction of grain size was noticed in OsPLC1 mutants.
• The increase in the grain size and the grain yield of OE lines were associated with the improvement of cell length and expression levels of a set of genes related to cell expansion, contrarily, the decrease in OsPLC1 mutant grain size and yield were linked to declined cell length and expression levels of related genes.
• No significant differences, in terms of the grain quality of mature seeds, were found in OE and OsPLC1 mutants, with compared to those in Nipponbare (Nip).
• In summary, our study suggests that OsPLC1 could modulate rice flowering time and grain size.
• Preferential expression of OsPLC1 is detected at the heading stage of rice, OsPLC1 overexpression results in early flowering, increased-grain size and yield; however, opposing phenotypes produced in the OsPLC1 mutants.
• The expression levels of subset genes, which are involved in the control of flowering time in rice, were altered in the plants of OE and OsPLC1.
• OsPLC1 overexpression (OE) produced rice plants with early flowering, whereas OsPLC1 loss-of-function led to delay in flowering.
