ABSTRACT
LATERAL ORGAN BOUNDARIES DOMAIN (LBD) proteins are plant-specific transcription factors which are involved in many biological process of plant development, including lateral organ development, photomorphogenesis, pathogen response, pollen development and plant regeneration. Here, we report new functions of LBD proteins that participate in the regulation of heading date and yield in rice. OsLBD37 and OsLBD38 are two class II type LBD proteins, function as transcriptional activators. Overexpression of OsLBD37 and OsLBD38 separately causes delayed heading date and increased yield. Both OsLBD37 and OsLBD38 are expressed in rhythmic pattern, and their proteins are localized in the nucleus. 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. These data indicates that OsLBD37 and OsLBD38, may function as novel regulators of heading date and crop yield in rice.
