Figure 5 Overexpression of PtrWRKY75 enhanced drought tolerance under short-term drought conditions.
(A) Morphological differences between wild-type (WT) andPtrWRKY75 -overexpressing (OE) lines in short-term drought experiments. Scale bars =10 cm. Data are means ± SE (n = 6).
(B) Net photosynthesis rate–drought duration curve. Data are means ± SE (n = 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: **P < 0.01.
(C) Stomatal conductance–drought duration curve. Data are means ± SE (n = 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: **P < 0.01.
(D) Transpiration–drought duration curve. Data are means ± SE (n= 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: *P ≤ 0.05; **P < 0.01.
(E) Leaf relative water content under non-stress and drought conditions. Data are means ± SE (n = 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: **P < 0.01.
(F) Water loss from detached leaves. Data are means ± SE (n = 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: *P ≤ 0.05; **P < 0.01.
(G) Leaf relative electrical conductance under non-stress and drought conditions. Data are means ± SE (n = 6). Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Asterisks denote significant differences: **P < 0.01.
