genotyping of the Tos17 insertion mutant Oryza sativa

Protein Variants Comment Organism
additional information generation of an OsCPS4 knockdown mutant, cps4-tos. Because Tos17 is inserted into the third intron of OsCPS4, the mature OsCPS4 mRNA is detected in the cps4-tos mutant as well as the wild type, screening Tos17 mutant lines using PCR. Mature OsCPS4 transcript levels in the cps4-tos mutant are about one sixth those in the wild-type. The cps4-tos mutant is more susceptible to rice blast fungus than the wild-type, possibly due to lower levels of momilactones and oryzalexin S in the mutant Oryza sativa
