Abstract:

In plant, protein tyrosine phosphatases (PTPs) and protein kinases control reversible phosphorylation, and the former plays critical roles in growth, organism development, hormones response, signal transduction and stresses response. This paper focused on classification, biological function and signaling pathways of PTPs in growth, abiotic and biotic stresses responses, in order to provide theoretical basis for future scientific research.

Key words: protein tyrosine phosphatase; stresses response; physiological function; signaling pathway
