Download scientific diagram | Performance of Ubi::OsBURP16 transgenic rice under cold stress. (a) Seedlings of OsBURP16-overexpressing lines (OE) and wild-type (ZH10) at trefoil stage were treated at 4 °C for 8 h. The leaves of lines OE3 and OE4 started rolling, while the leaves of ZH10 remained normal. The boxed parts in the top panel are enlarged as a detail (lower panel). Scale bar = 5 cm. (b) Two-week-old seedlings were treated at 4 °C for 72 h, and then allowed to recover for 7 d. Scale bars = 5 cm. (c) Survival rates of the cold-treated plants after 7 d of recovery. Data represent means ± SD (n = 16 for each replicate) of three independent experiments. One asterisk and two asterisks indicate significant differences at P ≤ 0.05 and P ≤ 0.01 compared with ZH10 by Student's t-test, respectively. (d) Relative ion leakage in rice leaves after 4 °C treatment for 60 h and 108 h. Data represent means ± SD of three biological replicates. One asterisk indicates significant difference at P ≤ 0.05 compared with corresponding ZH10 by Student's t-test. from publication: Overexpression of stress-inducible OsBURP16, the β subunit of polygalacturonase 1, decreases pectin content and cell adhesion and increases abiotic stress sensitivity in rice | Polygalacturonase (PG), one of the hydrolases responsible for cell wall pectin degradation, is involved in organ consenescence and biotic stress in plants. PG1 is composed of a catalytic subunit, PG2, and a non-catalytic PG1β subunit. OsBURP16 belongs to the PG1β-like | Polygalacturonase, Pectins and Abiotic Stress | ResearchGate, the professional network for scientists.
