Chlorophyll (Chl) degradation causes leaf yellowing during senescence or under stress
conditions. For Chl breakdown, STAY-GREEN1 (SGR1) interacts with Chl catabolic …

Gibberellins (GAs) are essential regulators of plant development, and DELLAs are negative
regulators of GA signaling. The mechanism of GA-dependent transcription has been …

Ethylene and abscisic acid (ABA) both accelerate senescence of detached Arabidopsis
leaves. We previously showed that suppression of Phospholipase Dδ (PLDδ) retarded ABA …

Senescence is not only an important developmental process, but also a responsive
regulation to abiotic and biotic stress for plants. Stay-green protein plays crucial roles in …

Abstract Gibberellins (GAs) and brassinosteroids (BRs) are important phytohormones that
control plant development and responses to environmental cues by involving DELLA …

The plant growth-repressing DELLA proteins (DELLAs) are known to represent a
convergence point in integration of multiple developmental and environmental signals in …

Leaf senescence is the terminal stage of leaf development. Both light and the plant hormone
ethylene play important roles in regulating leaf senescence. However, how they coordinately …

Nitric oxide (NO) has been known to preserve the level of chlorophyll (Chl) during leaf
senescence. However, the mechanism by which NO regulates Chl breakdown remains …

Loss of green color in leaves results from chlorophyll (Chl) degradation in chloroplasts, but
little is known about how Chl catabolism is regulated throughout leaf development. Using …

The last phase of leaf development, generally referred to as leaf senescence, is an integral
part of plant development that involves massive programmed cell death. Due to a sharp …
