From: Roles of SlETR7, a newly discovered ethylene receptor, in tomato plant and fruit development
Gene expression profile of ETRs in tomato. a–g Total RNA was isolated from different tissues (root, stem, leaf, and flower) and fruit pericarp + skin at different development stages (IMG, immature green; MG, mature green; Br, breaker; Br1, breaker + 1 day to Br7, breaker + 7 days). The RNA expression of all SlETRs were calculated relative to ETR1 levels in the root by using Actin and EF1α as reference genes. Data show the mean ± SD, n = 3; h heat map of clustering analysis of SlETRs expression during fruit development and ripening. i qPCR analysis of SlETR expression in response to 10 ppm exogenous ethylene in 2-week old seedlings. Data represent the mean ± SD, n = 3. Statistical analyses were performed using t-test comparing the air treatment with ethylene treatment, *P < 0.05, ***P < 0.001
