This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development. It has been recently identified that a new transport mechanism (AMF1 ) mediates ammonium transport across legume root nodule cellular membranes. AMF1 was identified through a transcriptional interaction with a membrane localised bHLHm1 transcription factor. Both bHLHm1 and AMF1 belong to a unique chromosomal regulatory locus common across sequenced dicot plant species.

本项目旨在研究调控位点在植物铵转运调控中的作用，以及促进这种相互作用的相互作用的遗传和生化信号。铵是植物生长发育的重要营养源。最近发现一种新的转运机制（AMF1）介导铵离子跨豆科植物根瘤细胞膜转运。AMF1通过与膜定位的bHLHm1转录因子的转录相互作用来鉴定。bHLHm1和AMF1都属于在测序的双子叶植物物种中常见的独特的染色体调控位点。
