Stress-responsive a-dioxygenase expression in tomato roots
Alpha-dioxygenase (a-DOX) enzymes catalyse the oxygenationof fatty acids to yield anewly identifiedgroupof oxylipins that play a role in protecting tissues from oxidative damage and cell death. In tomato (Lycopersicon esculentum Mill.) a-DOX was identified as saltregulated by differential display of mRNA, and is represented by a small gene family comprising at least three members: LEa-DOX1, -2,...
متن کاملSequence Evolution and Expression Regulation of Stress-Responsive Genes in Natural Populations of Wild Tomato
The wild tomato species Solanum chilense and S. peruvianum are a valuable non-model system for studying plant adaptation since they grow in diverse environments facing many abiotic constraints. Here we investigate the sequence evolution of regulatory regions of drought and cold responsive genes and their expression regulation. The coding regions of these genes were previously shown to exhibit s...
متن کاملEpigenetic marks in an adaptive water stress-responsive gene in tomato roots under normal and drought conditions
Tolerance to water deficits was evolutionarily relevant to the conquest of land by primitive plants. In this context, epigenetic events may have played important roles in the establishment of drought stress responses. We decided to inspect epigenetic marks in the plant organ that is crucial in the sensing of drought stress: the root. Using tomato as a crop model plant, we detected the methylate...
متن کاملExpression of some stress-responsive genes in tomato plants treated with ABA and sulfonamide compounds. Leila Zeinali Yedegari1 and Nayer Mohammadkhani2*
Drought causes an increase in some gene expression in plant tissues such as plasma membrane intrinsic proteins type 1 (PIP1), 9-cis-epoxycarotenoid dioxygenase (NCED) SlAREB1. The effects of exogenous abscisic acid (ABA) and two sulfonamide compounds, namely, sulfacetamide (Sa) and sulfasalazine (SS) were studied on gene expression of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under...
متن کاملMetabolic transition in mycorrhizal tomato roots
Beneficial plant-microorganism interactions are widespread in nature. Among them, the symbiosis between plant roots and arbuscular mycorrhizal fungi (AMF) is of major importance, commonly improving host nutrition and tolerance against environmental and biotic challenges. Metabolic changes were observed in a well-established symbiosis between tomato and two common AMF: Rhizophagus irregularis an...
