The rice Os01g0178600 was reported as OsCDR1 in 2009 by researchers from India.

Annotated Information

Gene Symbol

• Os01g0178600 <=> OsCDR1

Function

• Plant aspartic proteases (AP) play key roles in the regulation of biological processes, such as the recognition of pathogens and pests and the induction of effective defense responses.
• The rice OsCDR1 from encodes a predicted aspartate protease.
• The rice OsCDR1 plays an important role during the disease resistance response.

Phenotypic analysis

• Ectopic expression of OsCDR1 in Arabidopsis and rice conferred enhanced resistance against bacterial and fungal pathogens.
• The enhanced disease resistance observed in transgenic plants was correlated with induction of patho-genesis-related gene expression and was shown by mutational analysis to be dependent on AP activity of the trans-gene-encoded product.
• OsCDR1 accumulates in intercellular fluids (IF) in transgenic plants.
• Infiltration of IF from trans-genic Arabidopsis plants into leaves of wild-type (WT) Arabidopsis induced the systemic defense response.

Expression

• Expression of OsCDR1 was activated upon treatments with benzothiadiazole and salicylic acid, which are signal molecules in plant disease resistance responses.
