• Information
  • Symbol: Osgrp-2,OsGRP2
  • MSU: LOC_Os10g31330
  • RAPdb: Os10g0450900
• Publication
  • Structure, expression pattern and chromosomal localization of the rice Osgrp-2 gene, 2003, Sci China C Life Sci.
  • The promoter of a rice glycine-rich protein gene, Osgrp-2, confers vascular-specific expression in transgenic plants, 2003, Planta.
  • Cell wall Glycine-rich Protein2 is involved in tapetal differentiation and pollen maturation, 2020, J Plant Res.
• Genbank accession number
  • U40708
• Key message
  • 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
