Background Jasmonates are important regulators in plant responses to biotic and abiotic
stresses as well as in development. Synthesized from lipid-constituents, the initially formed …

Communication between source organs (exporters of photoassimilates) and sink organs
(importers of fixed carbon) has a pivotal role in carbohydrate assimilation and partitioning …

Plants initiate leaf senescence to relocate nutrients and energy from aging leaves to
developing tissues or storage organs for growth, reproduction, and defense. Leaf …

The increasing demand for food and the heavy yield losses in primary crops due to global
warming mean that there is an urgent need to improve food security. Therefore …

Programmed cell death (PCD) is a ubiquitous genetically regulated process consisting in an
activation of finely controlled signaling pathways that lead to cellular suicide. Although some …

Drought stress triggers mature leaf senescence, which supports plant survival and
remobilization of nutrients; yet leaf senescence also critically decreases post-drought crop …

Reactive oxygen species (ROS) and salicylic acid (SA) are two factors regulating leaf
senescence and defense against pathogens. However, how a single gene integrates both …

Wounding stress leads to leaf senescence. However, the underlying molecular mechanism
has not been elucidated. In this study, we investigated the role of the MdVQ10–MdWRKY75 …

Rose (R osa hybrida) is one of the most important ornamental plants worldwide; however,
senescence of its petals terminates the ornamental value of the flower, resulting in major …

Selenium (Se) exhibits a “double-edged” behavior in animal and human nutrition. It is a
micronutrient required in low concentrations by animals and humans, but toxic at high …
