Toward Systems Understanding of Leaf Senescence: An Integrated Multi-Omics Perspective on Leaf Senescence Research [PDF]
Molecular Plant, 2016 Leaf senescence is a complex but tightly regulated developmental process involving a coordinated sequence of multiple molecular events, which ultimately leads to death of the leaf. Efforts to understand the mechanistic principles underlying leaf senescence have been largely made by transcriptomic, proteomic, and metabolomic studies over the past decade.

Repeated summer drought and re-watering during the first growing year of oak (Quercus petraea) delay autumn senescence and bud burst in the following spring [PDF]
, 2016 Climate change predicts harsher summer droughts for mid-latitudes in Europe. To enhance our understanding of the putative impacts on forest regeneration, we studied the response of oak seedlings (Quercus petraea) to water deficit.

Plant Signaling & Behavior, 2009 Senescence is the last stage of development of a leaf, and is marked by a progressive degradation of cellular components and their recycling to other organs of a plant. We recently performed a transcriptomic analysis of leaf senescence in the legume model Medicago truncatula. Changes in gene expression reflected the profound physiological rearrangement

Intercropping and Nitrogen Fertilization Altered the Patterns of Leaf Senescence in Sorghum
International Journal of Agronomy, 2021 Leaf senescence regulates grain yield. However, the modulation of leaf senescence in sorghum under legume-based intercrop systems and nitrogen (N) fertilization is not known.

Oxidative Stress and Leaf Senescence [PDF]
Insight Botany, 2011 Senescence is an important developmental process that leads to the cell death through highly regulated genetically controlled processes in plants. Biotic and abiotic Oxidative stresses can also artificially induce senescence and increase the production of reactive oxygen species (ROS) specifically in chloroplast. One of the important oxidative stresses

Overexpression of AHL9 accelerates leaf senescence in Arabidopsis thaliana
BMC Plant Biology, 2022 Background Leaf senescence, the final stage of leaf growth and development, is regulated by numerous internal factors and environmental cues. Ethylene is one of the key senescence related hormones, but the underlying molecular mechanism of ethylene ...

Leaf senescence: progression, regulation, and application [PDF]
Molecular Horticulture, 2021 AbstractLeaf 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 remobilization which is essential for plants’ fitness. The initiation and progression of leaf senescence are regulated by a variety of internal and external factors ...

LSD: a leaf senescence database [PDF]
Nucleic Acids Research, 2010 By broad literature survey, we have developed a leaf senescence database (LSD, http://www.eplantsenescence.org/) that contains a total of 1145 senescence associated genes (SAGs) from 21 species. These SAGs were retrieved based on genetic, genomic, proteomic, physiological or other experimental evidence, and were classified into different categories ...

Chloroplast dismantling in leaf senescence
Journal of Experimental Botany, 2021 Abstract In photosynthetic plant cells, chloroplasts act as factories of metabolic intermediates that support plant growth. Chloroplast performance is highly influenced by environmental cues. Thus, these organelles have the additional function of sensing ever changing environmental conditions, thereby playing a key role in harmonizing ...

Cytokinin inhibition of leaf senescence [PDF]
Plant Signaling & Behavior, 2013 The senescence delaying effect of cytokinin is well known, however, the details behind how this process occurs remain unclear. Efforts to improve understanding of this phenomenon have led to the identification in Arabidopsis of specific cytokinin signaling components through which senescence signal responses are regulated.
