Gene Details:

• MSU gene ID: LOC_Os10g31330
• RAPdb gene ID: Os10g0450900
• Gene Symbol: Osgrp-2 OsGRP2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsGRP2 participated in establishment of the cellwall network during early tapetum development.
• The tapetal cell walls of an OsGRP2 mutant did not thicken at the pollen mothercell stage, as a result, pollen maturation and fertility rate decreased.
• High OsGRP2 expression was detected in male-floral organs, and OsGRP2 was distributed in the tapetum.
• In conclusion, our results indicate that OsGRP2 plays important roles in the differentiation and function of the tapetum.
