NtCIPK11 Confers Salt and Drought Tolerance in Arabidopsis

March 3, 2021

Researchers from Nanjing Forestry University, China, reported in BMC Plant Biology a protein from the salt-tolerant plant, Nitraria tangutorum, which confers tolerance to salt and drought to Arabidopsis.


Calcineurin B-like protein-interacting protein kinases (CIPKs) are a group of plant-specific protein kinases, which react to calcium signaling and have vital functions in the physiological and developmental adaptation of plants to adverse environments. The functions of CIPKs from salt-tolerant plants are still yet to be known, thus limits the use of such CIPKs in enhancing the tolerance of salt-susceptible plants to abiotic stresses.

The researchers studied the NtCIPK11 gene from N. tangutorum expressed in Arabidopsis to analyze its function in salt and drought tolerance. When the gene was overexpressed in Arabidopsis, the seed germination was observed to be improved under saline conditions. Furthermore, the transgenic Arabidopsis plants exhibited vigorous growth under salt stress and longer roots than the wild-type plants under salt or drought conditions.
