Catalase (CAT) is an extensively studied if somewhat enigmatic enzyme that is at the heart
of eukaryotic antioxidant systems with a canonical role in peroxisomal function. The CAT …

Senescence represents the final developmental act of the leaf, during which the leaf cell is
dismantled in a coordinated manner to remobilize nutrients and to secure reproductive …

Leaf senescence is regulated by diverse developmental and environmental factors.
Exogenous jasmonic acid (JA) can induce leaf senescence, whereas auxin suppresses this …

Leaf senescence is a genetically controlled dismantling programme that enables plants to
efficiently remobilise nutrients to new growing sinks. It involves substantial metabolic …

Developmental age is a strong determinant of stress responses in plants. Differential
susceptibility to various environmental stresses is widely observed at both the organ and …

Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both
the accumulation of specific toxic ions (eg Na+) and changes in leaf hormone relations are …

Senescence and programmed cell death are important features for plant development. By
allowing nutrient recycling and reallocation all along plant life, senescence contributes to the …

Highlights•Explanation of the window concept and competence to senesce.•Transcriptional
networks controlling developmental senescence are introduced from the senescence …

Within the last decade, NAC transcription factors have been shown to play essential roles in
senescence, which is the focus of this review. Transcriptome analyses associate …

Leaf senescence, as the last stage of leaf development, is regulated by diverse
