Journal ArticleDOI
A gene induced by the plant hormone abscisic acid in response to water stress encodes a glycine-rich protein
Jordi Gómez,Demetrio Sánchez-Martínez,Demetrio Sánchez-Martínez,Virginia Stiefel,Joan Rigau,Pere Puigdomènech,Montserrat Pagès +6 more
TL;DR: The isolation of complementary DNA and genomic clones of a gene that is ABA-inducible in the maize embryo, and whose messenger RNA accumulates in epidermial cells, which is also induced by water stress and wounding in leaves is described.
Journal ArticleDOI
The brown midrib3 (bm3) mutation in maize occurs in the gene encoding caffeic acid O-methyltransferase.
TL;DR: It is shown that two independent brown midrib3 (bm3) mutations have resulted from structural changes in the COMT gene, which encodes the enzyme O-methyltransferase, involved in lignin biosynthesis.
Journal ArticleDOI
Propranolol in prevention of recurrent bleeding from severe portal hypertensive gastropathy in cirrhosis.
R.M. Pérez-Ayuso,Josep M. Piqué,Jackie Bosch,Enrique Quintero,R. Valderrama,Josep M. Bordas,Joan Rodés,Julián Panés,Josep Maria Viver,Alexandra Gonzalez,Rafael Esteban,Renata M. Perez,Luis Rodrigo,Joan Rigau +13 more
TL;DR: Long-term propranolol treatment significantly reduces the frequency of rebleeding from severe PHG, and may improve the prognosis of cirrhotic patients with this disorder.
Journal ArticleDOI
ZmMYB31 directly represses maize lignin genes and redirects the phenylpropanoid metabolic flux.
Silvia Fornalé,Xinhui Shi,Chenglin Chai,Antonio Encina,Sami Irar,Montserrat Capellades,Elisabet Fuguet,Josep Lluís Torres,Pere Rovira,Pere Puigdomènech,Joan Rigau,Erich Grotewold,John Gray,David Caparrós-Ruiz +13 more
TL;DR: In this article, the role of maize R2R3-myB factor ZmMYB31 in the control of the phenylpropanoid pathway was investigated in Arabidopsis thaliana.
Journal ArticleDOI
Down-Regulation of Caffeic Acid O-Methyltransferase in Maize Revisited Using a Transgenic Approach
Joël Piquemal,Simon Chamayou,Isabelle Nadaud,Michel Beckert,Yves Barrière,Isabelle Mila,Catherine Lapierre,Joan Rigau,Pere Puigdomènech,Alain Jauneau,Catherine Digonnet,Alain-Michel Boudet,Deborah Goffner,Magalie Pichon +13 more
TL;DR: To the authors' knowledge, this is the first time that an AS strategy has been applied to modify lignin biosynthesis in a grass species.
