Web3 Nov 2024 · We show here that ectopic expression of the peptides IRONMAN (IMA1) and IMA2 improves growth on calcareous soil by inducing biosynthesis and secretion of the catecholic coumarin 7,8-dihydroxy-6-methoxycoumarin (fraxetin) via increased expression of MYB72 and SCOPOLETIN 8-HYDROXYLASE, a response that is strictly dependent on …
Web20 Mar 2024 · In Arabidopsis thaliana, scopoletin 8-hydroxylase mediates the final step in the biosynthesis of fraxetin, a coumarin with a catechol moiety, which is secreted by roots of iron-deficient plants at elevated pH to mobilize iron. Iron (Fe) is an essential mineral nutrient and an important factor for the composition of natural plant communities. Web12 Apr 2024 · Leaf color mutants are ideal materials for studying the regulatory mechanism of chloroplast development and photosynthesis. We isolated a cucumis melo spontaneous mutant (MT), which showed yellow-green leaf phenotype in the whole growing period and could be inherited stably.
