Fig. 2From: Genome-wide survey of sucrose non-fermenting 1-related protein kinase 2 in Rosaceae and expression analysis of PbrSnRK2 in response to ABA stressAlignment of the amino acid sequences of PbrSnRK2s and AtSnRK2s. The serine/threonine protein kinase active site signature and the protein kinase ATP-binding region signature are indicated by a green box (a green pentacle) and red box (a red pentacle), respectively. Domain I and Domain II are marked by black boxes at the C-terminusBack to article page
