Hormone Treatments in Studying Leaf Senescence

2018
As the last stage of plant development, senescence can be regulated by a large number of signals such as aging, reproductive growth, nutrient availability, and stresses. Various plant hormones have been shown to be involved in regulating plant senescence.

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.

Leaf Senescence: Signals, Execution, and Regulation

2005
Leaf senescence is a type of postmitotic senescence. The onset and progression of leaf senescence are controlled by an array of external and internal factors including age, levels of plant hormones/growth regulators, and reproductive growth. Many environmental stresses and biological insults such as extreme temperature, drought, nutrient deficiency ...

Control of Leaf Senescence by Auxins

Nature, 1959
THE considerable knowledge which has accumulated over the past thirty years suggests that differentiation, growth and senescence of plant cells is closely linked to the auxin status of the tissue. Investigations by Shoji, Addicott and Swets1 have shown that differentiating and enlarging tissues of the green leaves of Black Valentine bean contain a ...

Chloroplast Control of Leaf Senescence

2013
Chloroplasts have an active role in the induction and course of senescence through signals, derived from reactive oxygen species (ROS), exiting to the cytosol. In this way, leaf chloroplasts mimic the role of mitochondria in the apoptosis of non-photosynthetic organs. Oxylipins, magnesium-protoporphyrin IX (Mg-ProtoIX) and proteins are the best studied

Leaf senescence and gene expression.

CABI Reviews, 2009
Abstract The long-standing view of leaf senescence as an organized genetically controlled process has received convincing support from recent genome-wide studies of differential gene expression. Many hundreds of senescence-associated genes (SAGs) appear to be up- or down-regulated for the sake of nutrient salvage, including a wide array of ...

Anthocyanins in autumn leaf senescence

2002
Abstract Anthocyanins are synthesized during leaf senescence in certain plants across virtually all biomes, but are most spectacular in the autumn foliage of temperate deciduous forests. The patterns of color production in senescing foliage depend at least partly upon species composition and their phenology.
