Cellulase from Trichoderma harzianum interacts with roots and triggers induced systemic resistance to foliar disease in maize
Trichoderma harzianum is well known to exhibit induced systemic resistance (ISR) to Curvularia leaf spot. We previously reported that a C6 zinc finger protein (Thc6) is responsible for a major contribution to the ISR to the leaf disease, but the types of effectors and the signals mediated by Thc6 from Trichoderma are unclear. In this work, we demonstrated that two hydrolases, Thph1 and Thph2, f...
متن کاملFoliar Diseases Affected by Residue
residues on the soil surface to retard soil erosion, insulate the soil, and conserve soil moisture. This residue consists of leaves, leaf sheaths, ear husks, and stalks of corn that decompose very slowly on the soil surface. The relationship of surface residue to corn diseases can be divided into two categories: (1) a source of inoculum of disease-causing organisms, and (2) environment modifica...
متن کاملSoil solarization in various agricultural production systems
Soil solarization is a natural, hydrothermal process of disinfesting soil of plant pests that is accomplished through passive solar heating. Solarization occurs through a combination of physical, chemical, and biological mechanisms, and is compatible with many other disinfestation methods to provide integrated pest management. Commercially, it is used on a relatively small scale worldwide as a ...
متن کاملFusarium diseases as the main soil borne fungal pathogen on plants and their control management with soil solarization in Iran
The most frequently soil-borne fungal pathogens on plants are Fusarium species that make high economical damages in various agricultural locations in Iran. Our studies show that Fusarium species cause significant yield losses in main crops especially potato, pea, bean, wheat, corn and rice in several parts of the country. The diseases resulted in yield losses to the extent of 30 to 70% in the f...
متن کاملDeciphering the hormonal signalling network behind the systemic resistance induced by Trichoderma harzianum in tomato
Root colonization by selected Trichoderma isolates can activate in the plant a systemic defense response that is effective against a broad-spectrum of plant pathogens. Diverse plant hormones play pivotal roles in the regulation of the defense signaling network that leads to the induction of systemic resistance triggered by beneficial organisms [induced systemic resistance (ISR)]. Among them, ja...
