Expression of OsCHIs in rice leaves in response to UV treatment was analyzed using qRT-PCR. Rice plants treated with UV irradiation were collected at the designated time points and used to examine the expression of OsCHIs. A ubiquitin gene (OsUBQ5) was amplified using specific primers and used as an internal control. The expression level of each OsCHI gene was presented as the relative expression compared to the OsUBQ5 mRNA level. Asterisks indicate significant differences (p < 0.05, t-test) between UV-untreated and UV-treated samples. qRT-PCR analysis was performed on the triplicated biological samples.
