  2013 MAR 21 (VerticalNews) -- By a News Reporter-Staff News Editor at Agriculture Week -- Fresh data on Alkenes are presented in a new report. According to news reporting originating from Qingdao, People's Republic of China, by VerticalNews correspondents, research stated, "Hydrogen peroxide (H2O2) is an important signaling molecule in ethylene-induced stomatal closure in Arabidopsis thaliana. Early studies on the sources of H2O2 mainly focused on NADPH oxidases and cell-wall peroxidases. ...read more

  2012 DEC 13 (VerticalNews) -- By a News Reporter-Staff News Editor at Agriculture Week -- New research on Alkenes is the subject of a report. According to news reporting originating in Qingdao, People's Republic of China, by VerticalNews journalists, research stated, "Pharmacological, laser scanning confocal microscopic (LSCM), and spectrophotographic approaches were used to study the roles of hydrogen sulfide (H2S) and nitric oxide (NO) in signaling transduction of stomatal movement in response to ethylene in Vicia faba L. Ethylene treatment resulted in the dose-dependent stomatal closure under light, and this effect was blocked by the inhibitors of H2S biosynthesis in V faba L. Additionally, ethylene induces H2S generation and increases L-/D-cysteine desulfhydrase (pyridoxalphosphate-dependent enzyme) activity in leaves of V. faba L. Inhibitors of H2S biosynthesis have no effect on the ethylene-induced stomatal closure, NO accumulation, and nitrate reductase (NR) activity in guard cells or leaves of V. faba L. Moreover, the ethylene-induced increase of H2S levels and L-/D-cysteine desulfhydrase activity declined when NO generation was inhibited. ...read more

  2012 SEP 13 (VerticalNews) -- By a News Reporter-Staff News Editor at Agriculture Week -- Fresh data on Alkenes are presented in a new report. According to news reporting originating from Louvain, Belgium, by VerticalNews correspondents, research stated, "Changes in ethylene biosynthesis, respiration and firmness were studied during on-tree ripening, controlled atmosphere (CA) storage and shelf-life of 'Jonagold' apples. Particular attention was paid to the influence of harvest time on subsequent ripening during CA storage and shelf-life and on the effect of treatment with the ethylene inhibitor 1-MCP. ...read more
