Increased capacity for sucrose uptake leads to earlier onset of protein accumulation in developing pea seeds

Rosche, Elke; Blackmore, Daniel; Offler, Christina E; Patrick, John W


Pea (Pisum sativum L.) cotyledons, overexpressing a potato sucrose transporter (StSUT1), were used to explore the hypothesis that sucrose stimulates the onset of storage protein biosynthesis. The study focused on the transition between pre-storage and storage phases of seed development. During this period supply of sucrose and hexose to transgenic cotyledons was unaffected by StSUT1 expression. However, protoplasmic levels of sucrose but not hexoses were elevated in transgenic cotyledons. Total...[Show more]
