From: Rice Basic Helix-Loop-Helix 079 (OsbHLH079) Delays Leaf Senescence by Attenuating ABA Signaling
OsbHLH079 negatively regulates natural leaf senescence in rice. A Phenotypes of WT, osbhlh079-D, OsbHLH079-OE, osbhlh079-1, and osbhlh079-2 at 0, 30, and 50 DAH grown in the field. Scale bars = 20 cm. B Comparison of leaf phenotypes among WT, osbhlh079-D, OsbHLH079-OE, osbhlh079-1, and osbhlh079-2 plants during natural senescence. Flag leaves from the plants in (A) were photographed, and the images shown are representative of three independent flag leaves. Scale bars = 2 cm. C, D Changes in total chlorophyll content (C) and Fv/Fm ratio (D) of flag leaves under natural senescence conditions. Means and standard deviations were obtained from four independent plants. Asterisks denote statistically significant differences compared to WT, as determined by the two-tailed Student’s t-test (**P < 0.01 and ***P < 0.001). These experiments were performed twice with similar results. Chl, chlorophyll; DAH, days after heading; FW, fresh weight; NS, not significant
