Gene Details:

• MSU gene ID: LOC_Os03g57660 ,LOC_Os03g57670
• RAPdb gene ID: Os03g0790600
• Gene Symbol: PLA3 OsLBD3-7 OsLBD37
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• However, in contrast to pla1 and pla2, PLA3 showed pleiotropic phenotypes including enlarged embryo, seed vivipary, defects in SAM maintenance and aberrant leaf morphology.
• Consistent with these pleiotropic phenotypes, PLA3 is expressed in the whole plant body, and is involved in plant hormone homeostasis.
• Here we report the identification of the rice gene PLASTOCHRON3 (PLA3)/GOLIATH (GO) that regulates various developmental processes including the rate of leaf initiation (the plastochron).
• PLA3 exhibits similar phenotypes to pla1 and pla2- a shortened plastochron, precocious leaf maturation and rachis branch-to-shoot conversion in the reproductive phase.
• Microscopy of flag leaf cross-sections indicated that overexpression of OsLBD3-7 led to a decrease in both bulliform cell size and number.
• These results indicated that OsLBD3-7 might acts as an upstream regulatory gene of bulliform cell development to regulate leaf rolling, which will give more insights on the leaf rolling regulation mechanism.
• OsLBD3-7 works as a transcription activator and its protein is located on the plasma membrane and in the nucleus.
• Overexpression of OsLBD37 and OsLBD38 separately causes delayed heading date and increased yield.
• These data indicates that OsLBD37 and OsLBD38, may function as novel regulators of heading date and crop yield in rice.
• Both OsLBD37 and OsLBD38 are expressed in rhythmic pattern, and their proteins are localized in the nucleus.
• OsLBD37 and OsLBD38, two class II type LBD proteins, are involved in the regulation of heading date by controlling the expression of Ehd1 in rice.
• Further analysis revealed that OsLBD37 and OsLBD38 delayed heading date by down-regulating the expression of the florigen genes Hd3a and RFT1 through key regulator of heading date Ehd1.
• OsLBD37 and OsLBD38 are two class II type LBD proteins, function as transcriptional activators.
