An HR-Induced Tobacco Peroxidase Gene Is Responsive to Spermine, but Not to Salicylate, Methyl Jasmonate, and Ethephon

In Tobacco mosaic virus (TMV)-infected tobacco plants carrying the N resistance gene, a hypersensitive reaction or response (HR) occurs to enclose the virus in the infected tissue.Although a contribution of peroxidases to the resistance has been proposed, no evidence has been Bandages presented that tobacco peroxidase genes respond to HR.Here, we d

Longevity: epigenetic and biomolecular aspects

Many aging theories and their related molecular mechanisms me and you have been proposed.Simple model organisms such as yeasts, worms, fruit flies and others have massively contributed to their clarification, and many genes and pathways have been associated with longevity regulation.Among them, insulin/IGF-1 plays a key and evolutionary conserved r
