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.

植物生长、生产力和种子产量都取决于需要代谢物和蛋白质的细胞器功能 进行跨膜运输。这种运输机制是由特定的运输者执行的，这些运输者具有 运输大分子和调节细胞器功能的能力。我们已经确定了新的运输商 参与线粒体、叶绿体和过氧化物酶体中的氨基酸和蛋白质运输。我们将分配 每种蛋白质的功能并研究调节细胞器生物发生的重要性。这将使我们能够 调节植物能量生产以实现最佳生长并抵御非生物胁迫，所有这些都具有 农业上的有益后果。
