Chloroplasts overproduce reactive oxygen species (ROS) under unfavorable environmental
conditions, and these ROS are implicated in both signaling and oxidative damage. There is …

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 …

Reactive oxygen species (ROS) are generated and consumed in living organism for normal
metabolism. Paradoxically, the overproduction and/or mismanagement of ROS have been …

Plants have evolved sophisticated mechanisms to recycle intracellular constituents, which
are essential for developmental and metabolic transitions; for efficient nutrient reuse; and for …

Chlorophyll (Chl) is indispensable for photosynthesis. In association with Chl-binding
proteins (CBPs), it is responsible for light absorption, excitation energy transfer, and charge …

We applied 15N labeling approaches to leaves of the Arabidopsis thaliana rosette to
characterize their protein degradation rate and understand its determinants. The progressive …

Rapid protein degradation and replacement is an important response to photodamage and
a means of photoprotection by recovering proteostasis. Protein turnover and translation …

Turnover of dysfunctional organelles is vital to maintain homeostasis in eukaryotic cells. As
photosynthetic organelles, plant chloroplasts can suffer sunlight-induced damage. However …

The endoplasmic reticulum, chloroplasts, and mitochondria are major plant organelles for
protein synthesis, photosynthesis, metabolism, and energy production. Protein homeostasis …

Plant immunity is tightly controlled by a complex and dynamic regulatory network, which
ensures optimal activation upon detection of potential pathogens. Accordingly, each …
