Description
Summary:Abstract The exposure of plant roots to soil-related stresses, including drought, high temperatures, salinization, and nutrient deficiency, is on the rise due to climate change caused by human activities. A systematic literature review was conducted, which revealed evidence for conserved genes that modulate root system architecture under specific stress conditions. A collection of Arabidopsis thaliana mutants displaying a root phenotype distinct from the wild type is available in The Arabidopsis Information Resource database. Gene expression data was gathered for specific genes in response to selected abiotic stress treatments. K-means clustering, and fold change analyses identified 118 genes that were upregulated and 185 genes that were downregulated. A dedicated phenotyping approach was used to ascertain that lack of nutrients induced the transition from a ‘steep, cheap, and deep’ root morphotype to a ‘topsoil foraging’ root morphotype in the Columbia- 0 reference genotype. The anticipated role of ISOPENTENYLTRANSFERASE 3, LIPOXYGENASE 1, and WEE1 KINASE HOMOLOG as negative regulators of root growth in response to multiple stress signals was assayed. Further research with the candidate genes identified in this study may reveal promising targets for crop improvement.
