OMICS International organises 3000+ Global Conferenceseries Events every year across USA, Europe & Asia with support from 1000 more scientific societies and Publishes 700+ Open Access Journals which contains over 50000 eminent personalities, reputed scientists as editorial board members.

Systemic Acquired Resistance

Defense to plant pathogens is activated by molecules originating from the host and the pathogen itself, such as pathogen-associated molecular patterns (PAMPs) and secondary metabolites. This allows for the establishment of a local defense response, as well as for the generation of a secondary signal(s) involved in the activation of a systemic defense response, the so-called systemic acquired resistance (SAR). Early detection of the pathogen triggers a cascade of events, often leading to limiting it to the initial site of infection via programmed cell death . Several endogenous molecules involved in the activation of the defense response have been described, such as salicylic acid, jasmonate, and cell wall fragments from the host and pathogen. Additionally, different abiotic factors activate broad-spectrum resistance such as heat, cold and other physical factors, suggesting that at some points these pathways converge. OMICS Group International is one of the leading Open Access Publishers which is publishing 700+ peer-reviewed journals with the support of 50,000+ editorial board members as editorial team and aimed to disseminate the scholarly knowledge to the scientific society. OMICS Group also organizing 3000+ International Scientific Conferences and events yearly all over the world with the support of 1000+ Scientific associations worldwide.
