Prolonged deficits cause leaf senescence, ripening delays, and carryover effects.

Takasaki, H. et al. SNAC-As, stress-responsive NAC transcription factors, mediate ABA-inducible leaf senescence.
We envisage that integration of multi-omics leaf senescence data will enable us to address unresolved questions regarding leaf senescence, including determining the molecular principles that coordinate concurrent and ordered changes in biological events during leaf senescence.
This review focuses on recent milestones in leaf senescence research obtained using multi-omics technologies, as well as future endeavors toward systems understanding of leaf senescence processes.
It became evident that the nutrient supply is crucial in this context and strongly affects leaf senescence and grain maturation.
In general, leaf senescence was extended under warming, whereas the post-fruit leaf stage was shortened under cooling (Fig. 3).
The optimized light distribution within the canopy can delay leaf senescence, especially for triangle plants.
Guttation has been shown to play a crucial role in controlling leaf senescence and photosynthesis.
Finally, we provide current illustrations of epigenomic, proteomic, and metabolomic landscapes of leaf senescence.
Furthermore, leaf senescence can be retarded locally by the application of cytokinins, hormones that stimulate plant cell division.
