Influence of Ethylene Signaling in the Crosstalk Between Fe, S, and P Deficiency Responses in .

Front Plant Sci 2021 30;12:643585. Epub 2021 Mar 30.

Department of Agronomy (DAUCO-María de Maeztu Unit of Excellence), Edificio Celestino Mutis, Campus de Rabanales CeiA3, Universidad de Córdoba, Córdoba, Spain.

To cope with P, S, or Fe deficiency, dicot plants, like , develop several responses (mainly in their roots) aimed to facilitate the mobilization and uptake of the deficient nutrient. Within these responses are the modification of root morphology, an increased number of transporters, augmented synthesis-release of nutrient solubilizing compounds and the enhancement of some enzymatic activities, like ferric reductase activity (FRA) or phosphatase activity (PA). Once a nutrient has been acquired in enough quantity, these responses should be switched off to minimize energy costs and toxicity. Read More
