Leaf senescence can be triggered and promoted by a large number of developmental and
environmental factors. Numerous lines of evidence have suggested an involvement of …

Dark-induced senescence in the leaves of Pelargonium cuttings was manifested in
chlorophyll breakdown, and an increase in reactive oxygen species (ROS) levels followed …

Gibberellins (GAs) are plant hormones involved in the regulation of plant growth in response
to endogenous and environmental signals. GA promotes growth by stimulating the …

DELLA proteins are repressors of the gibberellin (GA) hormone signaling pathway that act
mainly by regulating transcription factor activities in plants. GAs induce DELLA repressor …

Proper timing of flowering is essential for reproduction of plants. Although it is well known
that both light and gibberellin (GA) signaling play critical roles in promoting flowering in …

Several lines of evidence have implicated the involvement of the phytohormone gibberellin
(GA) in modulating leaf senescence in plants. However, upstream transcription factors (TFs) …

Leaf senescence is a complex biological process and defense responses play vital role for
rice development, their molecular mechanisms, however, remain elusive in rice. We herein …

The transition from etiolated to green seedlings involves a shift from hypocotyl growth-
promoting conditions to growth restraint. These changes occur through a complex light …

Bioactive gibberellins (GAs) are diterpene phytohormones that modulate growth and
development throughout the whole life cycle of the flowering plant. Impressive advances …

The phytohormone abscisic acid (ABA) modulates plant growth and developmental
processes such as leaf senescence. In this study, we investigated the role of the Arabidopsis …
