Plant growth-defense trade-offs: Molecular processes leading to physiological changes (2021)
Figueroa-Macías, Juan Pablo; García, Yamilet Coll; Núñez, María; Díaz, Katy; Olea, Andres F.; Espinoza, Luis J. (MDPI AG, 2021-01-02)In order to survive in a hostile habitat, plants have to manage the available resources to reach a delicate balance between development and defense processes, setting up what plant scientists call a trade-off. Most of these ... -
