Atypical kinase family, ABC1 (the activity of bc1 complex) genes play essential roles in plant growth, development and responses to be environmental stresses. Here, a novel gene, AtSIA1 (A. thaliana Salt-Induced ABC1 kinase 1) was cloned and characterized in Arabidopsis. Semi-quantitative RT-PCR analysis revealed that it constitutively expressed and mainly induced by salt treatment. AtSIA1-GFP fusion analysis showed that AtSIA1 is localized in chloroplasts. Transgenic plants with overexpression of AtSIA1 show higher tolerance to salt stress than that of the Col-0 and the knock-out mutant sia1 during seedling growth. Taken together, our results suggested that AtSIA1 may be involved in salt stress tolerance in Arabidopsis.
