Two EguCBF1 genes overexpressed in Eucalyptus display a different impact on stress tolerance and plant development

17/05/2010 00:00

Marie Navarro, Céline Ayax, Yves Martinez, Joan Laur, Walid El Kayal, Christiane Marque and Chantal Teulières Résumé: Two C-repeat binding factor genes (EguCBF1a/b), isolated from E. gunnii and differentially cold-regulated, were constitutively overexpressed in a cold-sensitive...

Reactive Oxygen Species during Plant-microorganism Early Interactions

10/02/2010 00:00

Amrit K. Nanda, Emilie Andrio, Daniel Marino, Nicolas Pauly and Christophe Dunand Résumé: Reactive Oxygen Species (ROS) are continuously produced as a result of aerobic metabolism or in response to biotic and abiotic stresses. ROS are not only toxic by-products of aerobic metabolism, but are...
