A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.

Mycoparasitism of fungal plant pathogens by Trichoderma species is a complex process that involves the production and coordinated secretion of cell-wall degrading enzymes. Genes implicated in mycoparasitism by Trichoderma atroviride contain motifs in the promoter region, designated MYRE1-MYRE4, that are proposed to act as binding sites for a global inducer of the mycoparasitic response. The aim...

Biological control agents (BCA) are beneficial organisms that are applied to protect plants from pests. Many fungi of the genus Trichoderma are successful BCAs but the underlying mechanisms are not yet fully understood. Trichoderma cf. atroviride strain LU132 is a remarkably effective BCA compared to T. cf. atroviride strain LU140 but these strains were found to be highly similar at the DNA seq...

Biodiversity of phylloplane and endophytic fungi have been considered as one of the rich source of novel natural compounds of biological activities and a high level of structure diversity on the leaf surfaces. Bioactive components produced by phylloplane and endophytes have shown promising potentiality towards human health. In this juncture, it is necessary to understand and manipulate this imp...

Background and objectives: Silymarin is a unique flavonoid complex with documented hepatoprotective properties. Silybum marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. In the present investigation Trichoderma strainsSilybum marianum hairy root cultures interactions have been studied. Methods: The effects of two...

Twenty isolates of Bacillus species obtained from livestock manure composts and cotton-waste composts were tested for their antagonistic effects in vitro against three green mold pathogens of mushrooms (Trichoderma harzianum, T. koningii, and T. viridescens). However, there exists a possibility Bacillus species may have antagonistic effects against mushrooms themselves, and thus the same 20 iso...

The area planted with avocado crops in Colombia has been growing rapidly recent years, especially for export varieties such as Hass. increase coincided increased phytosanitary problems, where pathogens fungi of the genus Verticillium spp. are becoming economic importance. objective this study was to evaluate different control strategies wilt disease caused by spp., under vitro, net house, and f...

Trichoderma asperellum has been fronted as a biocontrol agent of root-knot nematodes on tomato and French beans in Kenya. Research on the effect of T. asperellum on growth of Rhizobium species is lacking yet the two interact within the rhizosphere particularly when T. asperellum is applied as a biocontrol agent. Legume roots and Rhizobium species have symbiotic relationship resulting in biologi...
