Phosphoproteomic of Arabidopsis Highly-ABA Induced1 identifies AT-Hook Like10 phosphorylation required for stress growth regulation

The poster will be represented entitle: Drought-related signaling mechanism: Phosphoproteomic of Arabidopsis Highly-ABA Induced1 identifies AT-Hook Like10 phosphorylation required for stress growth regulation. The mechanisms plants use to detect and signal abiotic stress are not well understood but have major implications for plant productivity during periods of drought and other environmental stresses.Highly ABA-Induced 1 (HAI1) has especially prominent effects on drought phenotypes such as growth and proline accumulation. To investigate how HAI1 affects drought response, phosphoproteomic analysis of the hai1-2 mutant was conducted for plants under unstressed conditions or drought treatment. By identifying HAI1-affected phosphoproteins and functionally important AHL10 phosphorylation site, these results elucidate HAI1 and AHL10 function and also demonstrate a mechanism plants use to balance maximal growth versus robust response to environmental stress.
