We produced near isogenic lines (NILs) for three purple leaf genes, Pl, Plw and Pli of rice with a genetic background of T-65 to characterize each allele. Three NILs each had characteristic tissue-specific anthocyanin pigmentation. T-65 Plw was newly found to make the root purple when the root was exposed to light. To explore the inducible characteristics of the three genes, we examined the responses of the three NILs to UV-B irradiation.
