Genbank accession number

• Further the microscopic analysis revealed that OsPRP3 enhances the cell wall integrity in the cold tolerant plant and confers cold-tolerance in rice
• Taken together, the results suggested that OsPRP3 is a cell wall protein, playing a crucial role in determining extracellular matrix structure of floral organs
• Here we report a novel flower-specific PRP designated OsPRP3 from rice
• Expression analysis showed that the OsPRP3 transcript was mainly present in rice flower and accumulated abundantly during the late stage of the flower development
• Microscopic analysis of the RNAi mutant flower revealed that blocking OsPRP3 function caused significant defects in floral organogenesis
• OsPRP3, a flower specific proline-rich protein of rice, determines extracellular matrix structure of floral organs and its overexpression confers cold-tolerance
• Our overexpression plants showed a significant increase in cold tolerance than the WT plants which is conferred by the accumulation of OsPRP3 protein during cold treatment
