Mitochondria are essential organelles involved in energy production and specific metabolic pathways in plant cells that require the import of cytosolic transfer RNA (tRNA) to function. To date our knowledge on the mechanisms of tRNA import is limited. This project seeks to characterise putative receptors and mechanisms with the purpose of exploiting these insights to allow for the manipulation and modification of macromolecule targeting to mitochondria. The ability to modify or alter mitochondrial biogenesis and activity may allow for new approaches to be undertaken to increase plant growth, productivity and resistance to stress.

线粒体是植物细胞中参与能量产生和特定代谢途径的重要细胞器，需要输入胞质转移RNA(TRNA)才能发挥作用。到目前为止，我们对tRNA导入机制的了解还很有限。这个项目试图描述假定的受体和机制，目的是利用这些洞察力来允许操纵和修饰以线粒体为靶点的大分子。改变或改变线粒体生物发生和活性的能力可能允许采取新的方法来提高植物的生长、生产力和抗逆性。
