Aging and stress explain the earlier start of leaf senescence in trees in warmer years: translating the latest findings on senescence regulation into the DP3 model (v1.1) [PDF]
Geoscientific Model DevelopmentLeaf senescence ends the growing season of deciduous trees, affecting the amount of atmospheric CO2 sequestered by forests. Therefore, some climate models integrate projected leaf senescence dates to simulate the carbon cycle.

Differences in Sugar Accumulation and Mobilization between Sequential and Non-Sequential Senescence Wheat Cultivars under Natural and Drought Conditions. [PDF]
PLoS ONE, 2016 Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves.

Counteractive Effects of Sugar and Strigolactone on Leaf Senescence of Rice in Darkness
Agronomy, 2021 Plant hormones strigolactones (SLs) were recently reported to induce leaf senescence. It was reported that sugar suppresses SL-induced leaf senescence in the dark; however, the mechanism of the crosstalk between SLs and the sugar signal in leaf ...

Leaf Senescence and GABA Shunt [PDF]
Bioinformation, 2014 Leaf senescence is highly regulated and complex developmental process that involves degradation of macromolecules as well as its recycling. Senescence process involves loss of chlorophyll, degradation of proteins, nucleic acid, lipid and mobilization of nutrients through its transport to the growing parts, developing fruits and seeds.

Hormonal changes during salinity-induced leaf senescence in tomato (Solanum lycopersicum L.) [PDF]
, 2008 Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in the regulation of this process. Tomato plants (Solanum

Function of Protein Kinases in Leaf Senescence of Plants
Frontiers in Plant Science, 2022 Leaf senescence is an evolutionarily acquired process and it is critical for plant fitness. During senescence, macromolecules and nutrients are disassembled and relocated to actively growing organs.

The transcriptome of Populus in elevated CO2 reveals increased anthocyanin biosynthesis during delayed autumnal senescence [PDF]
, 2010 The delay in autumnal senescence that has occurred in recent decades has been linked to rising temperatures. Here, we suggest that increasing atmospheric CO2 may partly account for delayed autumnal senescence and for the first time, through transcriptome

AtWRKY75 positively regulates age-triggered leaf senescence through gibberellin pathway
Plant Diversity, 2021 WRKY transcription factors play essential roles during leaf senescence. However, the mechanisms by which they regulate this process remains largely unknown.
