Journal ArticleDOI
Dirigent proteins in plants: modulating cell wall metabolism during abiotic and biotic stress exposure.
Candelas Paniagua,Anna Bilkova,Anna Bilkova,Phil A. Jackson,Siarhei A. Dabravolski,Willi Riber,Vojtech Didi,Josef Houser,Nora Gigli-Bisceglia,Michaela Wimmerová,Eva Budinská,Thorsten Hamann,Jan Hejátko +12 more
TL;DR: The ample evidence for stress-induced dirigent gene expression is summarized, suggesting the role of DIRs in adaptive responses, and a preliminary bioinformatics-based characterization of the AtDIR family is presented.
Journal ArticleDOI
Rapid deposition of extensin during the elicitation of grapevine callus cultures is specifically catalyzed by a 40-kilodalton peroxidase.
Phil A. Jackson,Carla I. R. Galinha,Cristina Silva Pereira,Ana Sofia Fortunato,Nelson C. Soares,Sara Amancio,Candido P.P. Ricardo +6 more
TL;DR: This work concludes that it has identified and purified an EP from grapevine callus that is responsible for the catalysis of GvP1 deposition in situ during elicitation and suggests that GVP1 and this EP play an important combined role in grapevine cell wall defense.
Journal ArticleDOI
A biochemical and molecular characterization of LEP1, an extensin peroxidase from lupin.
Nicholas J. Price,Carla Pinheiro,Cláudio M. Soares,David A. Ashford,Cândido Pinto Ricardo,Phil A. Jackson +5 more
TL;DR: Optimal conditions for the in vitro oxidation of other phenolic substrates included 1.5–3.0 mm peroxide at pH 5.0 and neutral pH, suggesting that physiological changes in pH and peroxide in muro could heavily influence the extensin cross-linking activity of LEP1 in vivo.
Journal ArticleDOI
The contribution of extensin network formation to rapid, hydrogen peroxide-mediated increases in grapevine callus wall resistance to fungal lytic enzymes
TL;DR: The results indicate that hydrogen peroxide-induced increases in resistance to digestion by fungal lytic enzymes require a co-operative action between network extensin formation and the electrostatic interaction of additional wall proteins with the extracellular matrix.
Journal ArticleDOI
Proteomics of ionically bound and soluble extracellular proteins in Medicago truncatula leaves
TL;DR: It is indicated that IB and IF proteins are functionally distinct fractions of the apoplast, which will be useful in future studies investigating the role of apoplastic proteins in plant processes.
