Phenotypic characterization of oscrlk2. (a, b) Creation and detection of oscrlk2. (c) RVA curve of WT and oscrlk2 mutants. (d) Milled rice morphology of c1-c3 (Bar = 5 mm). Grain appearance was evaluated using the WSeen analysis system. The white milled rice grains in the middle are the chalky grains. Transverse sections of mature seeds from c4-c6 (Bar = 0.5 mm). SEM images of transverse sections of mature seeds from c7-c9 (Bar = 10 μm). (e–j) Viscosity (cP)\, GT (°C), chalkiness degree (%), AAC (%), sucrose contents (mg/g), amylose and amylopectin contents (%) in mature endosperm of WT and oscrlk2 mutants. Values are shown as means ± SD (n = 3). **P < 0.01 and *P < 0.05 (Student’s t test)
