Journal ArticleDOI
Dual regulation of cytosolic ascorbate peroxidase (APX) by tyrosine nitration and S-nitrosylation

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
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.

Journal ArticleDOI
Mechanical wounding induces a nitrosative stress by down-regulation of GSNO reductase and an increase in S-nitrosothiols in sunflower (Helianthus annuus) seedlings
Mounira Chaki,Raquel Valderrama,Ana Fernández-Ocaña,Alfonso Carreras,María V. Gómez-Rodríguez,José Rafael Pedrajas,Juan C. Begara-Morales,Beatriz Sánchez-Calvo,Francisco Luque,Marina Leterrier,Francisco J. Corpas,Juan B. Barroso +11 more
TL;DR: It is proposed that mechanical wounding triggers the accumulation of SNOs, specifically GSNO, due to a down-regulation of GSNOR activity, while NO2-Tyr increases, and a process of nitrosative stress is induced in sunflower seedlings and SNOs constitute a new wound signal in plants.
