Figure 6. CTB4a mediates ATP supply and improves rice yield.

Figure 6

(a) ATP synthase activity, ATP content and photosynthetic rate in leaves of Towada, NIL1913 and overexpression lines under CS-PT for 3 days. (b) ATP synthase activity, ATP content and photosynthetic rate in leaves of HY and ctb4a mutant under CS-PT for 3 days. (c,d) ATP content in panicles of overexpression lines (c) and ctb4a mutant (d). (e) Relative seed setting of Towada and NIL1913. Exogenously applied ATP (5 mM) rescued the cold sensitivity of Towada. Data represent means±s.d. (n=15). (f) Filled grain number per-panicle, thousand-kernel weight and yield per-plant in Towada, NIL1913 and transgenic plants under CS-HAA. Data represent means±s.d. (n=30). (g) Statistical results for seed setting of Nip and AtpB overexpression lines under CS-PT. Data represent means±s.d. (n=5). All P values were calculated by Student's t-test. **P<0.01, *P<0.05.
