In this project, the key transport systems mediating salt sequestration in halophytes are planned to be characterised and linked with cell genetic and metabolic profiles. Salinity is a major environmental hurdle affecting crop production around the world. Halophytes (naturally salt-loving plants) use specialised structures, called salt bladders, to sequester excessive salt outside their metabolically active parts. This feature is not utilised by crops however, and no information is available about the molecular mechanisms by which salt is pumped into bladder cells. This knowledge will allow breeders to utilise this, previously unexplored, trait to improve crop performance under conditions of salinity.

在该项目中，计划将盐生植物中介导盐螯合的关键运输系统与细胞遗传和代谢谱相关联。盐度是影响世界各地作物生产的主要环境障碍。盐生植物（天然喜盐植物）使用特殊的结构，称为盐囊，将多余的盐隔离在代谢活跃的部分之外。然而，作物并没有利用这一特征，也没有关于盐被泵入膀胱细胞的分子机制的信息。这一知识将使育种者能够利用这一以前未被探索过的特性来改善作物在盐度条件下的表现。
