Leaf senescence is a developmentally programmed cell death process that is influenced by a variety of endogenous signals and environmental factors. Here, we report that MPK3 and MPK6, two Arabidopsis mitogen-activated protein kinases (MAPKs or MPKs), and

Species-specific effects of elevated ozone on wetland plants and decomposition processes [PDF]
Seven species from two contrasting wetlands, an upland bog and a lowland rich fen in North Wales, UK, were exposed to elevated ozone (150 ppb for 5 days and 20 ppb for 2 days per week) or low ozone (20 ppb) for four weeks in solardomes.

Transcriptional analyses of natural leaf senescence in maize.
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 ...

A local regulatory network around three NAC transcription factors in stress responses and senescence in Arabidopsis leaves [PDF]
A model is presented describing the gene regulatory network surrounding three similar NAC transcription factors that have roles in Arabidopsis leaf senescence and stress responses. ANAC019, ANAC055 and ANAC072 belong to the same clade of NAC domain genes

Arabidopsis FHY3 and FAR1 Function in Age Gating of Leaf Senescence
Leaf senescence is the terminal stage of leaf development. Both light and the plant hormone ethylene play important roles in regulating leaf senescence.

Shade-Induced Leaf Senescence in Plants
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 ...

Ageing in plants:Conserved strategies and novel pathways [PDF]
Ageing increases chaos and entropy and ultimately leads to the death of living organisms. Nevertheless, single gene mutations substantially alter lifespan, revealing that ageing is subject to genetic control.

A Petunia homeodomain-leucine zipper protein, PhHD-Zip, plays an important role in flower senescence. [PDF]
Flower senescence is initiated by developmental and environmental signals, and regulated by gene transcription. A homeodomain-leucine zipper transcription factor, PhHD-Zip, is up-regulated during petunia flower senescence. Virus-induced gene silencing of

Damage Potential of Rose Chafer and Japanese Beetle (Coleoptera: Scarabaeidae) in Michigan Vineyards [PDF]
Responses of young non-fruiting grapevines, Vitis labrusca (L.) var. ‘Niagara’, to defoliation were examined at two stages of vine growth when beetles typically infest vineyards.

Arabidopsis defense against Botrytis cinerea : chronology and regulation deciphered by high-resolution temporal transcriptomic analysis [PDF]
Transcriptional reprogramming forms a major part of a plant’s response to pathogen infection. Many individual components and pathways operating during plant defense have been identified, but our knowledge of how these different components interact is ...
