Plasma membrane-localized SlSWEET7a and SlSWEET14 regulate sugar transport and storage in tomato fruits

摘要

a At the transcript level, SlSWEET genes were found to exist as 29 different members in Micro-Tom mature green (MG) fruits. b, c Relative expression of SlSWEET7a and SlSWEET14 during fruit development in Micro-Tom. BC2d, 2 days before flowering; AF0d flowering, AF2d 2 days after flowering, AF7d 7 days after flowering, AF14d 14 days after flowering, AF21d 21 days after flowering, MG mature green, BC breaking color, RR red ripe. d, e Gene expression of SlSWEET7a and SlSWEET14 in different tissues during fruit development in Micro-Tom. Different tissues such as the peduncles, sepals, total pericarp (including pulp and pericarp), placentas, vascular bundles, and septa were investigated during the MG, BC, and RR stages. The data are shown as the means ± SDs of three independently biological replicates
