Fig. 6From: Enhancing xanthine dehydrogenase activity is an effective way to delay leaf senescence and increase rice yieldAllantoin and allantoate content in wild-type and transgenic lines at different growth stages. The seedling, full heading and maturation stages of rice were grown to 14d, 60d, and 90d after sowing, respectively. The penultimate leaves were selected at seedling stage, and sword leaves are selected for the determination of allantoin (a) and allantoate (b) content at full heading and maturation stages. FW, fresh weight. Values are means±SEM, n = 3. Significant differences (P < 0.05) are denoted by different lowercase lettersBack to article page
