Leaf senescence, the last stage of leaf development, is a type of postmitotic senescence and
is characterized by the functional transition from nutrient assimilation to nutrient …

Melatonin is a pleiotropic molecule with multiple functions in plants. Since the discovery of
melatonin in plants, numerous studies have provided insight into the biosynthesis …

Heat stress and abscisic acid (ABA) induce leaf senescence, whereas melatonin (MT) and
gibberellins (GA) play critical roles in inhibiting leaf senescence. Recent research findings …

Leaf senescence is a highly coordinated, complicated process involving the integration of
numerous internal and environmental signals. Salicylic acid (SA) and reactive oxygen …

The plant hormone auxin regulates numerous aspects of plant growth and development.
Early auxin response genes mediate its genomic effects on plant growth and development …

Phytohormones participate in various processes over the course of a plant's lifecycle. In
addition to the five classical phytohormones (auxins, cytokinins, gibberellins, abscisic acid …

Adaptive plant responses to specific abiotic stresses or biotic agents are fine-tuned by a
network of hormonal signaling cascades, including abscisic acid (ABA), ethylene, jasmonic …

Many studies have been conducted to understand plant stress responses to salinity because
irrigation-dependent salt accumulation compromises crop productivity and also to …

Micro RNA s (mi RNA s) are small RNA s that regulate the expression of target genes post‐
transcriptionally; they are known to play major roles in development and responses to …

Degreening, caused by chlorophyll degradation, is the most obvious symptom of senescing
leaves. Chlorophyll degradation can be triggered by endogenous and environmental cues …
