Fig. 2From: Enhancing xanthine dehydrogenase activity is an effective way to delay leaf senescence and increase rice yieldThe relative expression level of OsXDH and XDH activity in wild-type and transgenic plants. a Expression analysis of OsXDH in rice seedlings cultured for 30 days. Ri3, Ri5, and Ri6 were XDH interference transgenic lines, and OE1, OE3, and OE9 were XDH over-expression transgenic lines. The internal reference gene was OsActin. b Enzyme activity analysis of XDH in rice seedlings cultured for 30 days. Soluble protein was extracted from rice seedling leaves grown for 30 days. Each lane in the gel was loaded with equal content soluble protein. XDH activity was detected in gel with hypoxanthine as substrateBack to article page
