Trichoderma species--opportunistic, avirulent plant symbionts.
TLDR
Root colonization by Trichoderma spp.Abstract:
Trichoderma spp. are free-living fungi that are common in soil and root ecosystems. Recent discoveries show that they are opportunistic, avirulent plant symbionts, as well as being parasites of other fungi. At least some strains establish robust and long-lasting colonizations of root surfaces and penetrate into the epidermis and a few cells below this level. They produce or release a variety of compounds that induce localized or systemic resistance responses, and this explains their lack of pathogenicity to plants. These root-microorganism associations cause substantial changes to the plant proteome and metabolism. Plants are protected from numerous classes of plant pathogen by responses that are similar to systemic acquired resistance and rhizobacteria-induced systemic resistance. Root colonization by Trichoderma spp. also frequently enhances root growth and development, crop productivity, resistance to abiotic stresses and the uptake and use of nutrients.read more

Plant-growth-promoting rhizobacteria.
TL;DR: This review restricts itself to bacteria that are derived from and exert this effect on the root and generally designated as PGPR (plant-growth-promoting rhizobacteria), which can be direct or indirect in their effects on plant growth.

Biological control of soil-borne pathogens by fluorescent pseudomonads
Dieter Haas,Geneviève Défago +1 more
TL;DR: Biocontrol strains of fluorescent pseudomonads produce antifungal antibiotics, elicit induced systemic resistance in the host plant or interfere specifically with fungal pathogenicity factors during root colonization.

The rhizosphere microbiome: significance of plant beneficial, plant pathogenic, and human pathogenic microorganisms
TL;DR: The main functions of rhizosphere microorganisms and how they impact on health and disease are reviewed and several strategies to redirect or reshape the rhizospheric microbiome in favor of microorganisms that are beneficial to plant growth and health are highlighted.

Acquisition of phosphorus and nitrogen in the rhizosphere and plant growth promotion by microorganisms
Alan Richardson,José Miguel Barea,Ann McNeill,Claire Prigent-Combaret,Claire Prigent-Combaret +4 more
TL;DR: Features of the rhizosphere that are important for nutrient acquisition from soil are reviewed, with specific emphasis on the characteristics of roots that influence the availability and uptake of phosphorus and nitrogen.

Enhanced enzymatic hydrolysis of langostino shell chitin with mixtures of enzymes from bacterial and fungal sources.
TL;DR: Fitted polynomial models indicated that there was synergy between prokaryotic and fungal enzymes for both hydrolysis of crab chit in and reduction of turbidity of colloidal chitin (primarily endo-type activity).

Timing of gliotoxin biosynthesis in the fungal biological control agentGliocladium virens (Trichoderma virens)
S. E. Wilhite,D. C. Straney +1 more
TL;DR: Results demonstrate that the regulation ofgliotoxin biosynthesis is a major determinant in the kinetics of gliotoxin appearance and focuses the need for further study on theregulation of gene expression.

Expression of induced systemic resistance in poinsettia cuttings against Rhizoctonia stem rot by treatment of stock plants with binucleate Rhizoctonia
J. Hwang,D. M. Benson +1 more
TL;DR: These results may be the first to demonstrate induced systemic resistance by BNR fungi during vegetation propagation where the biocontrol agent applied to roots of a stock plant was able to protect cuttings from Rhizoctonia solani during propagation.

Ethylene Biosynthesis-Inducing Endoxylanase Is Translocated through the Xylem of Nicotiana tabacum cv Xanthi Plants
TL;DR: The observation that a fungal protein that elicits plant defense responses can be translocated through the xylem suggests that plants respond to pathogen-derived extracellular proteins in tissues distant from the invading pathogen.

TL;DR: The latest results of molecular studies on the interaction of avirulence genes and matching resistance genes with Cladosporium fulvum are discussed, including the isolation of two new Avr genes, Avr2 and Avr4E and the description of an efficient method to identify early HR-related genes.
