Leaf Senescence: Systems and Dynamics Aspects
Annual Review of Plant Biology, 2019 Leaf senescence is an important developmental process involving orderly disassembly of macromolecules for relocating nutrients from leaves to other organs and is critical for plants’ fitness. Leaf senescence is the response of an intricate integration of various environmental signals and leaf age information and involves a complex and highly regulated

Annual Review of Plant Biology, 2007 Leaf senescence constitutes the final stage of leaf development and is critical for plants’ fitness as nutrient relocation from leaves to reproducing seeds is achieved through this process. Leaf senescence involves a coordinated action at the cellular, tissue, organ, and organism levels under the control of a highly regulated genetic program.

Molecular aspects of leaf senescence
Trends in Plant Science, 2000 Senescence is the last stage of leaf development and one type of programmed cell death that occurs in plants. The relationships among senescence programs that are induced by a variety of factors have been addressed at a molecular level in recent studies.

, 2006 Leaf senescence is currently considered the last stage of leaf development and is a genetically programmed process, highly regulated with recycling of reserves from the leaves to other storage organs (seeds, trunk, branches). Leaves of deciduous plants perceive the changing of the seasons in autumn and activate all the processes for the preparation for

Gene expression during leaf senescence
New Phytologist, 1994SUMMARYLeaf senescence is a hiphly‐controlled sequence of events comprising the final stage of development. Cells remain viable during the process and new gene expression is required. There is some similarity between senescence in plants and programmed cell death in animals.

The molecular genetic analysis of leaf senescence
Current Opinion in Biotechnology, 1997 The cloning of genes induced during leaf senescence and the study of their modes of regulation conducted in the past two years have revealed some of the molecular mechanisms underlying leaf senescence. The identification of genetic mutants that control leaf senescence in Arabidopsis thaliana opened up new possibilities for genetically analyzing leaf ...

Signal transduction in leaf senescence
Plant Molecular Biology, 2012Leaf senescence is a complex developmental phase that involves both degenerative and nutrient recycling processes. It is characterized by loss of chlorophyll and the degradation of proteins, nucleic acids, lipids, and nutrient remobilization. The onset and progression of leaf senescence are controlled by an array of environmental cues (such as drought,

Senescence constitutes the last phase of plant growth and is characterized by a series of degenerative events that decrease metabolic activities and cause the death of cells, tissues and organs. Yellowing of leaves is a morphological indicator of senescence, which results due to loss of green pigments, i.e., chlorophylls.

Transcriptional networks in leaf senescence
Current Opinion in Plant Biology, 2015Plant senescence is a natural phenomenon known for the appearance of beautiful autumn colors and the ripening of cereals in the field. Senescence is a controlled process that plants utilize to remobilize nutrients from source leaves to developing tissues.
