Os07g0490200

The rice gene Os07g0490200 was reported as OsCBT in 2009 by researchers from Korea.

Annotated Information

Gene Symbol

• Os07g0490200 <=> OsCBT, CBT

Function

• OsCBT gene, which encodes a calmodulin (CaM)-binding protein.
• OsCBT might act as a negative regulator on plant defense.

Mutation

• The oscbt-1 mutant exhibits reduced levels of OsCBT transcripts and no significant morphological changes compared to wild-type plant although the growth of the mutant is stunted. However, oscbt-1 mutants showed significant resistance to two major rice pathogens. The growth of the rice blast fungus Magnaporthe grisea, as well as the bacterial pathogen Xanthomonas oryzae pv. oryzae was significantly suppressed in oscbt-1 plants. Histochemical analysis indicated that the hypersensitive-response was induced in the oscbt-1 mutant in response to compatible strains of fungal pathogens.
• The researchers also observed significant increase in the level of pathogenesis-related genes in the oscbt-1 mutant even under pathogen-free condition.

Expression

• OsCBT expression was induced upon challenge with fungal elicitor.
