Annual Review of Phytopathology | Year: 2010

Structural and functional genomics investigations are making an important impact on the current understanding and application of microbial agents used for plant disease control. Here, we review the case of Trichoderma spp., the most widely applied biocontrol fungi, which have been extensively studied using a variety of research approaches, including genomics, transcriptomics, proteomics, metabolomics, etc. Known for almost a century for their beneficial effects on plants and the soil, these fungi are the subject of investigations that represent a successful case of translational research, in which 'omics-generated novel understanding is directly translated in to new or improved crop treatments and management methods. We present an overview of the latest discoveries on the Trichoderma expressome and metabolome, of the complex and diverse biotic interactions established in nature by these microbes, and of their proven or potential importance to agriculture and industry. © 2010 by Annual Reviews.

Plant Signaling and Behavior | Year: 2011

Alternative and ecological strategies are necessary and demanded for disease management in order to reduce the use of pesticides in agriculture. Thus, the use of biological control agents such as plant growth-promoting rhizobacteria (PGPR) or several strains of the beneficial fungus Trichoderma spp. to combat plant diseases is the basis of biocontrol of plant pathogens and is a good approach to reach this healthy and environmentally adequate objective. © 2011 Landes Bioscience.

Plant Signaling and Behavior | Year: 2012

Nitric oxide (NO) is a highly inducible molecule and overaccumulated during stress responses, such as drought, cold and pathogen infection. Several key developmental processes within a plant life cycle have been reported to be signaled by this gaseous molecule, and among them seed germination, de-etiolation, gravitropic response or root growth are wellcharacterized. The importance of NO as a plant growth and stress regulator is emerging considerably, despite the current knowledge about its signaling pathway is still limited. Therefore, the identification and characterization at the molecular level of NO targets is essential to get a deeper insight into this pathway. Here we characterize the effect of NO on root development in Arabidopsis and found that NO application reduces cell lengths in differentiation zone. Additionally, the contribution of the gibberellin (GA) signaling pathway to the NO root-related phenotypes, mainly through DELLA repressors, is also depicted. © 2012 Landes Bioscience.
