Linking cell wall dynamics to ABA homeostasis: polyamines and pectin fragments as cell wall invertase stimulators KU Leuven
Plants are continuously exposed to various biotic and abiotic stresses, and the phytohormone ABA fulfils a central role during these responses. Below and above certain ABA levels, normal plant growth and development is negatively affected. "Priming" with certain exogenous substances (e.g. sugars, polyamines) prepares plants to react more efficiently during subsequent stresses. The regulation of intracellular ABA concentrations (ABA ...
