NIK1-mediated translation suppression functions as a plant antiviral immunity m...
Zorzatto, Cristiane; Machado, João Paulo B.; Lopes, Kênia V. G.; Nascimento, Kelly J. T.; Pereira, Welison A.; Brustolini, Otávio J. B.Plants and plant pathogens are subject to continuous co-evolutionary pressure for dominance, and the outcomes of these interactions can substantially impact agriculture and food security^ 1–3 . In virus– plant interactions, one of the major mechanisms for plant antiviral immunity relies on RNA silencing, which is often suppressed by co-evolving virus suppressors, thus enhancing viral pathogenicity in susceptibl...
The molecular chaperone binding protein BiP prevents leaf dehydration-induced c...
Carvalho, Humberto H.; Brustolini, Otávio J. B.; Pimenta, Maiana R.; Mendes, Giselle C.; Gouveia, Bianca C.; Silva, Priscila A.; Silva, José Cleydson F.BiP overexpression improves leaf water relations during droughts and delays drought-induced leaf senescence. However, whether BiP controls cellular homeostasis under drought conditions or simply delays dehydration-induced leaf senescence as the primary cause for water stress tolerance remains to be determined. To address this issue, we examined the drought-induced transcriptomes of BiP-overexpressing lines and ...
Immune receptors and co-receptors in antiviral innate immunity in plants
Gouveia, Bianca C.; Calil, Iara P.; Machado, João Paulo B.; Santos, Anésia A.; Fontes, Elizabeth P. B.Plants respond to pathogens using an innate immune system that is broadly divided into PTI (pathogen-associated molecular pattern- or PAMP-triggered immunity) and ETI (effector-triggered immunity). PTI is activated upon perception of PAMPs, conserved motifs derived from pathogens, by surface membrane-anchored pattern recognition receptors (PRRs). To overcome this first line of defense, pathogens release into pl...
