Hormonal cross-talk in plants

Hormonal cross-talk in plants refers to the interactions between various plant hormones that regulate growth, development, and stress responses. Key hormones include auxins, gibberellins, cytokinins, ethylene, abscisic acid (ABA), and jasmonates. These hormones do not function in isolation; rather, they influence each other’s signaling pathways to fine-tune plant responses to environmental stimuli. For instance, the interaction between ABA and ethylene plays a crucial role in mediating drought responses and fruit ripening. Understanding these cross-talk mechanisms can aid in enhancing crop resilience and productivity, particularly under changing environmental conditions.
