STRK1 Improves the Grain Yield of Rice under Salt Stress at the Reproductive Stage.

(A) and (B) Phenotypic comparison of rice plants under salt stress. Salt stress of plants was initiated at the panicle development stage (top) by exposure to 1% NaCl as indicated (down), and then the plants were recovered with irrigation for 10 d and harvested.

(C) to (E) Panicle number (C), spikelet fertility (D), and grain yield (E) of STRK1-overexpressing and wild-type plants in (A) after 10 d of recovery. Data are presented as mean ± sd (n = 20,*P ≤ 0.05, **P ≤ 0.01, Student’s t test).

(F) to (H) Panicle number (F), spikelet fertility (G), and grain yield (H) of STRK1-RNAi and wild-type plants in (B) after 10 d of recovery. Data are presented as mean ± sd (n = 20,*P ≤ 0.05, **P ≤ 0.01, Student’s t test).
