Abstract

The study of plant death is completed by defining plant cell senescence. Senescence is an inseparable part of plant growth. Like many other plant processes, this is a genetic control program that is regulated by a set of environmental and genetic factors. These factors and their mechanisms respond to the relationship between sources and sinks in which glucose signals and hormonal regulation and cellular genetics play a major role. During senescence, nutrients such as nitrogen, phosphorus, and glucose are released from the breakdown of macromolecules in leaf cells, to be assigned to growing organs or storage tissues. Symptoms of Leaf senescence include chlorophyll loss, dehydration, and eventually plant death. Recognition of senescence is very necessary because with sufficient knowledge, senescence can be manipulated in the desired direction. For example, current molecular genetic approaches are used for postpone senescence, like blocking ethylene production or increasing cytokinin production. They are based on Plant hormone mechanisms. Plant storage products increase their life span. In order to understand Leaf senescence, many genetic SAGs, especially transcription factors and encoding components of transmission pathways, various gene functional methods are described.
