Figure Lengend Snippet: Phenotypes of the OsJAZ1 -OE plants and the jaz1 T-DNA insertion mutant plants under drought stress treatment at the seedling stage. (A) Schematic diagram of the OsJAZ1 gene and 4A-00845 T-DNA insertion mutant. UTR, ORF, and introns are indicated in the black box, white box, and line, respectively. (B) Expression levels of OsJAZ1 in the 4A-00845 homozygous line and Dongjin. (C) The expression levels of OsJAZ1 in the OE lines and WT ZH11. (D,E) Drought tolerance testing of jaz1 T-DNA mutant plants and over-expression plants. (D) The jaz1 mutant lines showed increased drought resistance. (E) The OsJAZ1 -OE plants were more sensitive to drought stress treatment compared to WT ZH11. (F,G) The survival rates of the transgenic and WT plants after recovery from drought stress treatment for 7 days. Mut-1 and mut-2 were heterozygous mutants segregated from 4A-00845. Error bars represent the SE of three replicates ( ∗∗∗ P < 0.005, Student’s t -test).
Article Snippet: The OsJAZ1 mutant line 4A-00845 in the background of the rice variety Dongjin ( Oryza sativa L. ssp. japonica ) was obtained from the POSTECH RISD .
