Journal ArticleDOI
Metabolism of reactive nitrogen species in pea plants under abiotic stress conditions.
Francisco J. Corpas,Mounira Chaki,Ana Fernández-Ocaña,Raquel Valderrama,José M. Palma,Alfonso Carreras,Juan C. Begara-Morales,Morad Airaki,Luis A. del Río,Juan B. Barroso +9 more
TL;DR: The results obtained suggest that low and high temperature, continuous light and high light intensity are abiotic stress conditions that can induce nitrosative stress in pea plants.
Journal ArticleDOI
Dual regulation of cytosolic ascorbate peroxidase (APX) by tyrosine nitration and S-nitrosylation
Juan C. Begara-Morales,Beatriz Sánchez-Calvo,Mounira Chaki,Raquel Valderrama,Capilla Mata-Pérez,Javier Lopez-Jaramillo,María N. Padilla,Alfonso Carreras,Francisco J. Corpas,Juan B. Barroso +9 more
TL;DR: Pea plants grown under saline (150mM NaCl) stress showed an enhancement of both APX activity and S-nitrosylated APX, as well as an increase of H2O2, NO, andS-nitrosothiol (SNO) content that can justify the induction of theAPX activity.
Journal ArticleDOI
Involvement of Reactive Nitrogen and Oxygen Species (RNS and ROS) in Sunflower–Mildew Interaction
Mounira Chaki,Ana Fernández-Ocaña,Raquel Valderrama,Alfonso Carreras,Francisco J. Esteban,Francisco Luque,María V. Gómez-Rodríguez,Juan C. Begara-Morales,Francisco J. Corpas,Juan B. Barroso +9 more
TL;DR: The results suggest that pathogens induce nitrosative stress in susceptible cultivars and the increase of tyrosine nitration of proteins can be considered a general biological marker of nitrosive stress in plants under biotic conditions.
Journal ArticleDOI
Protein tyrosine nitration in pea roots during development and senescence
Juan C. Begara-Morales,Mounira Chaki,Beatriz Sánchez-Calvo,Capilla Mata-Pérez,Marina Leterrier,José M. Palma,Juan B. Barroso,Francisco J. Corpas +7 more
TL;DR: The data as a whole reveal that protein tyrosine nitration is a nitric oxide-derived PTM prevalent throughout root development and intensifies during senescence.
Journal ArticleDOI
Protein targets of tyrosine nitration in sunflower (Helianthus annuus L.) hypocotyls
Mounira Chaki,Raquel Valderrama,Ana Fernández-Ocaña,Alfonso Carreras,Javier Lopez-Jaramillo,Francisco Luque,José M. Palma,José Rafael Pedrajas,Juan C. Begara-Morales,Beatriz Sánchez-Calvo,María V. Gómez-Rodríguez,Francisco J. Corpas,Juan B. Barroso +12 more
TL;DR: The results suggest that Tyr nitration occurs in plant tissues under physiological conditions that could constitute an important process of protein regulation in such a way that, when it is overproduced in adverse circumstances, it can be used as a marker of nitrosative stress.
