Carbon/Nitrogen Imbalance Associated with Drought-Induced Leaf Senescence in Sorghum bicolor. [PDF]
PLoS ONE, 2015 Drought stress triggers mature leaf senescence, which supports plant survival and remobilization of nutrients; yet leaf senescence also critically decreases post-drought crop yield.

Leaf Senescence by Magnesium Deficiency [PDF]
Plants, 2015 Magnesium ions (Mg2+) are the second most abundant cations in living plant cells, and they are involved in various functions, including photosynthesis, enzyme catalysis, and nucleic acid synthesis. Low availability of Mg2+ in an agricultural field leads to a decrease in yield, which follows the appearance of Mg-deficient symptoms such as chlorosis ...

Multiple Layers of Regulation on Leaf Senescence: New Advances and Perspectives
Frontiers in Plant Science, 2021 Leaf senescence is the last stage of leaf development and is an orderly biological process accompanied by degradation of macromolecules and nutrient recycling, which contributes to plant fitness.

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.

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 ...

High-resolution temporal profiling of transcripts during Arabidopsis leaf senescence reveals a distinct chronology of processes and regulation [PDF]
, 2011 Leaf senescence is an essential developmental process that impacts dramatically on crop yields and involves altered regulation of thousands of genes and many metabolic and signaling pathways, resulting in major changes in the leaf.
