ABSTRACT:
The mitogen-activated protein kinase (MAPK)
cascade is the most important mechanism in environmental responses and
developmental processes in plants. The OsMAPK2 gene has been found to function in plant tolerance to
diverse biotic/abiotic stresses. This
paper presents evidence that OsMAPK2 (Oryza sativa MAP kinase gene 2) is responsive to Pi deficiency and involved in Pi homeostasis. We found that full-length expression of OsMAPK2 was up-regulated in both rice
plants and cell culture in the absence of inorganic phosphate (Pi).
The transgenic rice and Arabidopsis plants overexpressing OsMAPK2 showed affected root development
and increased plant Pi content compared with wild-type plants.
Overexpression of OsMAPK2
controlled the expression of several Pi starvation-responsive genes.
Our results indicated that OsMAPK2 enables tolerance phosphate deficiency and is involved in Pi homeostasis.
