Chloroplast dismantling in leaf senescence [PDF]
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 ...

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 ...

Current Understanding of Leaf Senescence in Rice [PDF]
International Journal of Molecular Sciences, 2021 Leaf senescence, which is the last developmental phase of plant growth, is controlled by multiple genetic and environmental factors. Leaf yellowing is a visual indicator of senescence due to the loss of the green pigment chlorophyll. During senescence, the methodical disassembly of macromolecules occurs, facilitating nutrient recycling and ...

Shade-Induced Leaf Senescence in Plants
Plants, 2023 Leaf senescence is a vital developmental process that involves the orderly breakdown of macromolecules to transfer nutrients from mature leaves to emerging and reproductive organs. This process is essential for a plant’s overall fitness. Multiple internal and external factors, such as leaf age, plant hormones, stresses, and light environment, regulate ...

Rice Premature Leaf Senescence 2, Encoding a Glycosyltransferase (GT), Is Involved in Leaf Senescence [PDF]
Frontiers in Plant Science, 2018 Premature leaf senescence (PLS), which has a significant impact on yield, is caused by various underlying mechanisms. Glycosyltransferases, which function in glycosyl transfer from activated nucleotides to aglycones, are involved in diverse biological processes, but their roles in rice leaf senescence remain elusive. Here, we isolated and characterized

Transcriptional analyses of natural leaf senescence in maize.
PLoS ONE, 2014 Leaf senescence is an important biological process that contributes to grain yield in crops. To study the molecular mechanisms underlying natural leaf senescence, we harvested three different developmental ear leaves of maize, mature leaves (ML), early ...

Light-Mediated Regulation of Leaf Senescence [PDF]
International Journal of Molecular Sciences, 2021 Light is the primary regulator of various biological processes during the plant life cycle. Although plants utilize photosynthetically active radiation to generate chemical energy, they possess several photoreceptors that perceive light of specific wavelengths and then induce wavelength-specific responses.

Possible Roles of Strigolactones during Leaf Senescence
Plants, 2015 Leaf senescence is a complicated developmental process that involves degenerative changes and nutrient recycling. The progress of leaf senescence is controlled by various environmental cues and plant hormones, including ethylene, jasmonic acid, salicylic

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
