Deciphering organelle transport mechanisms in plants

点击翻译按钮获取中文摘要

Plant growth, productivity and seed yield all depend on organelle function which requires metabolites and proteins to be transported across membranes. This mechanism of transport is carried out by specific transporters that have the ability to transport macromolecules, and regulate organelle function. We have identified new transporters that are involved in amino acid and protein transport in the mitochondria, chloroplast and peroxisomes. We will assign function to each protein and investigate the importance in regulating organelle biogenesis. This will allow us to modulate plant energy production for optimal growth and to withstand abiotic stress, all of which have agriculturally beneficial consequences.
