Abstract Environmental stresses caused by climate change have severely affected agriculture in the present century; Salinity and drought have challenged most forecasts for increased agricultural production in the past few decades, therefore, different methods that reduce the effect of these stresses on plants have attracted scientists’ attention. The effect of beneficial soil microorganisms on soil health and increasing plants’ resistance to stresses is one of the solutions that researchers have paid attention to. This study investigated how Trichoderma species can be affected by the molecular and morphophysiological mechanisms of plants and improve their salt and drought resistance. This study also studied… More >

Abstract Meloidogyne incognita is a plant pathogen causing root-knot disease and loss of crop yield. The present study aimed to use Trichoderma harzianum as a biocontrol agent against plant-parasitic nematodes and used press mud, which is a solid waste by-product of sugarcane, as a biocontrol agent and biofertilizer. Therefore, the combined application of T. harzianum and press mud may enhance nematode control and plant growth. Elemental analysis of press mud using scanning electron microscopy (SEM) integrated with an Energy Dispersive X-ray (EDX) analyzer revealed the presence of different elements such as C, O, Mg, Si, P, K, Ca, Cu and Zn.… More >

Abstract We report the systematic survey of the binding free energies at the interface between a carbohydrate binding module (CBM) of Cel7A and the cellulose III_I crystal model using grid docking searches and molecular dynamics simulations. The two hydrophobic crystal surfaces were involved in the distinct energy minima of the binding free energy. The complex models, each with the CBM at the minimum energy position, stably formed in the solution state. The binding free energies of the cellulose III_I complex models, based on both static and dynamics states, were comparable to those of the native cellulose complex models. However, the cellulose… More >

Abstract Salt stress is one of the major abiotic stress in plants. However, traditional approaches are not always efficient in conferring salt tolerance. Experiments were conducted to understand the role of Trichoderma spp. (T. harzianum and T. viride) in growth, chlorophyll (Chl) synthesis, and proline accumulation of C. pepo exposed to salinity stress. There were three salt stress (50, 100, and 150 mM NaCl) lavels and three different Trichoderma inoculation viz. T. harzianum, T. viride, and T. harzianum + T. viride. Salt stress significantly declined the growth in terms of the shoot and root lengths; however, it was improved by the… More >

Abstract There is an increasing interest in developing nanoparticles with diverse biologic activities. To this end, we prepared 10 to 15 nm silver nanoparticles (AgNP) from native isolates of Trichoderma atroviride. Within this study, endophytic fungi hosted four medicinal plants in Saint Katherine Protectorate, South Sinai, Egypt have been isolated by surface sterilization technique on four isolation media. Ten species, based on their frequency of occurrence, out of twenty recovered taxa were tested for their capability to synthesize extracellular AgNPs. Trichoderma atroviride hosted Chiliadenus montanus was found to be the best candidate for the production of mycogenic AgNPs among all examined… More >

Abstract Fourteen native strains of Trichoderma spp. from wildand agricultural pathosystems in the state of Yucatan, Mexico, with growth-promoting ability of Capsicum chinense Jacq. seedlings were evaluated and antagonistic effect of their filtrate against second-stage juveniles (J2) of Meloidogyne incognita. The strains Th05-02 and Th27-08 showed the best significant effects on plant hight variable increments 55.57 and 47.62%, theTh07-04 with 29.48% more root length, theTh02-01 and Th07-04 isolates increased from 48.71 to 84.61% in volume radical and 53.40% of total dry biomass. Statistical analysis (p≤0.001) of Th43 and Th43-13-14 filtrates caused 100% mortality at 24 and 48h. In the test of… More >

Abstract Strains of Mucor, Penicillium and Trichoderma, able to use metsulfuron-methyl (MM) as a sole carbon and energy source, were isolated from agricultural soils in Argentina. This is the first time this ability is recorded in the Mucor or Trichoderma species. When the isolated strains were compared in relation to their capacity to use the herbicide, those of Trichoderma showed the best results. Because of this, they were selected for further assays. The effect of metsulfuron on growth in liquid media was tested. Also, the ability of conidia to germinate in water agar medium containing the target herbicide was evaluated. All… More >

Abstract We performed the inoculation of transgenic cotton seedlings with Trichoderma sp. strain ICA 4 to evaluate its effects on the physiological development of seedlings. Inoculated seedlings of transgenic cotton had higher development than non-inoculated seedlings. The range of values for relative growth, doubling time, height and number of leaves (0.04 g/g d; 16.88 days; 17.16 cm and 4.2, respectively) were significantly higher that those observed in non-inoculated plants (0.03 g/g day; 24.38 days; 12.33 cm and 2.6, respectively). Regarding radical architecture, inoculated seedlings with Trichoderma strain ICA 4 showed a higher percentage of roots of 2^nd (46%), 3^rd (73%) and… More >

Abstract In vitro tests were carried out, to evaluate the antagonist capacity of a strain of Trichoderma isolated from soil in La Cienega de Chapala, Michoacán, Mexico against Sclerotium cepivorum and Sclerotium rolfsii, casual agents of onion rot, an important disease in Mexico and the rest of the world. Percentages of radial growth inhibition (PRGI) were calculated every 24 h, until a rate of antagonism was obtained according to the Bell’s scale, as well as the percentages of inhibition of the production of sclerotia and their parasitism. The PRGI was 17.4% against S. rolfsii and 22.2% against S. cepivorum after 48… More >

Abstract The root knot nematode Meloidogyne spp. is an important endoparasite limiting the cultivation of horticultural species and affecting the plants of at least 3000 species, including grasses, vegetables, ornamentals, fruit and forest. The aim of this study was to estimate the potential of three species of Trichoderma as antagonists of M. incognita in plants of Capsicum chinense under greenhouse conditions. A bioassay was established with plants of C. chinense previously inoculated with Trichoderma spp. and transplanted to pots with sterile substrate; the plants were subsequently inoculated with 300 infective second-stage larvae (J₂) and 1000 larvae eggs of M. incognita.
