From: ABC1K10a, an atypical kinase, functions in plant salt stress tolerance
The abc1k mutants accumulate more ROS than the wild type under salt and osmotic stresses. (a) Phylogenetic tree of ABC1K proteins from Arabidopsis. The tree was constructed by comparing the amino acid sequences of all 17 ABC1K proteins encoded in the Arabidopsis thaliana genome. Three different clades were highlighted with different colors (green indicates the plastids clade; purple indicates the ancestral clade, and light pink indicates the mitochondria clade) according to previous reports [20, 21]. (b) NBT staining of the roots of wild type, abc1k11, abc1k10a, abc1k13, abc1k14 and abc1k15 mutant roots treated with 200 mM NaCl or 300 mM mannitol. Bars = 400 μm. k, abc1k. (c) Quantification of NBT staining intensity. Asterisks indicate statistically significant difference with wild type plants in each treatment. Error bars indicate ± SD (n = 15) (**P < 0.01, *P < 0.05, t-test)
