Journal ArticleDOI
Wound signalling in plants
TL;DR: Different jasmonic acid-dependent and -independent wound signal transduction pathways have been identified recently and partially characterized, and include reversible protein phosphorylation steps, calcium/calmodulin-regulated events, and production of active oxygen species.
Journal ArticleDOI
Ultraviolet light and ozone stimulate accumulation of salicylic acid, pathogenesis-related proteins and virus resistance in tobacco
TL;DR: It is reported that ultraviolet (UV)-C light or ozone induced biochemical responses similar to those induced by necrotizing pathogens and UV light, ozone fumigation and tobacco mosaic virus can activate a common signal-transduction pathway that leads to SA and PR-protein accumulation and increased disease resistance.
Journal ArticleDOI
Hydrogen Peroxide Stimulates Salicylic Acid Biosynthesis in Tobacco
TL;DR: It is suggested that H2O2 stimulates BA2H activity directly or via the formation of its substrate, molecular oxygen, in a catalase-mediated reaction and activates SA biosynthesis via two mechanisms.
Journal ArticleDOI
Ozone-induced responses in Arabidopsis thaliana: the role of salicylic acid in the accumulation of defense-related transcripts and induced resistance.
TL;DR: It is demonstrated that ozone activates at least two distinct signaling pathways, including a salicylic acid dependent pathway previously shown to be associated with the activation of pathogen defense reactions, and that this latter pathway also induces a protective response to ozone.
Journal ArticleDOI
Salicylic acid regulates flowering time and links defence responses and reproductive development
TL;DR: It is shown that UV-C light stress activates the transition to flowering in Arabidopsis thaliana through salicylic acid (SA), which regulates flowering time in non-stressed plants, as SA-deficient plants are late flowering.
