GSO1 is important for plant salt stress tolerance. Left: Loss-of-function mutants of GSO1 (gso1) exhibit reduced root and shoot growth in the presence of salt stress as compared to wildtype (Col). Middle: Salt stress induces enhanced GSO1 receptor kinase accumulation specifically in the root tip meristem and in the endodermis of the differentiation zone. The kinase SOS2 is present in the whole root; its protein accumulation is evenly enhanced upon salt stress. Right: Model of salt stressed Arabidopsis roots.
Newly discovered signalling pathway specifically protects the stem cells in the plant root from salt stress. GSO1 is important for plant salt stress tolerance.
