Fig. 1From: The sucrose non-fermenting-1-related protein kinases SAPK1 and SAPK2 function collaboratively as positive regulators of salt stress tolerance in riceThe phylogenetic tree of the SnRK2 family in Arabidopsis and rice. Two closely related protein kinases, OsSAPK1 and OsSAPK2, are involved in subclass II SnRK2 in rice. Subclass II SnRK2s in Arabidopsis and rice are indicated in redBack to article page
