Trichoderma species are known as excellent biocontrol agents against soil-borne pathogens that cause considerable crop losses. Eight strains of were isolated from five Egyptian regions. They identified based on translation elongation factor-1α (TEF1) sequencing four different species: asperellum, harzianum, viride, and longibrachiatum. Optimal growth conditions (temperature media), the phosphate solubilization capability evaluated in vitro. Further, ability these to antagonize Fusarium...
Plant-associated microbes play crucial roles in plant health and promote growth under stress. Tomato (Solanum lycopersicum) is one of the strategic crops grown throughout Egypt a widely vegetable worldwide. However, disease severely affects tomato production. The post-harvest (Fusarium wilt disease) food security globally, especially fields. Thus, an alternative effective economical biological treatment to was recently established using Trichoderma asperellum. role rhizosphere microbiota...
Abstract
 Plant uptake and assimilation of essential nitrogen compounds from the soil are mainly in form nitrate ammonium ions. transporters (NRTs) play a crucial role into roots. NRT structural analysis reveals mechanisms by which these function. Similarly, plant (AMTs) mediate ions, their has provided valuable information on mechanisms. After roots, metabolism pathway involves incorporation organic compounds. Glutamine synthetase (GS) glutamate synthase (GoGAT) master players this...
Plant diseases caused by fungal pathogens are responsible for severe damage to strategic crops worldwide. Late wilt disease (LWD) is a vascular that occurs late in maize development. Harpophora maydis, the causative agent of LWD, significant economic losses Egypt. Therefore, aim this study was control LWD using an alternative approach reduce use chemical pesticides. A combination Trichoderma viride, biocontrol agent, and Azospirillum brasilense, bacterial endophytic plant growth promoter,...
Trichoderma species are recognized as biocontrol agents with great potential in inhibiting fungal pathogens that cause significant crop losses. In this study, 15 isolates were collected from various Egyptian locations. Internal transcribed spacer sequencing revealed four different species; harzianum, asperellum, longibrachiatum, and viride. The antagonistic activity of against Fusarium oxysporum f. sp. capsici was evaluated vitro. effect on pepper growth plants the presence F. studied...
Global agriculture is a pivotal activity performed by various communities worldwide to produce essential human food needs. Plant productivity limited several factors, such as salinity, water scarcity, and heat stress. Salinity significantly causes short or long-term impacts on the plant photosynthesis mechanisms reducing photosynthetic rate of CO 2 assimilation limiting stomatal conductance. Moreover, disturbing status imbalance growth inhibition. Up-regulation phytohormones occurs in...
Abstract Background Root rot pathogens reported to cause considerable losses in both the quality and productivity of common bean ( Phaseolus vulgaris L.) pea Pisum sativum L.). It is an aggressive crop disease with detriment economic influence caused by Fusarium solani Rhizoctonia among other soil-borne fungal pathogens. Destructive plant diseases such as root have been managed last decades using synthetic pesticides. Main body Seeking economical eco-friendly alternatives combat that...
Thirteen Rhizobial isolates from root nodules of Faba beans (Vicia faba L.) were obtained eleven governorates, representing different agro-ecological, agro-climatic and soil conditions in Egypt.A polyphasic approach, including phenotypic genotypic techniques used to study their diversity.Rhizobium examined for ability tolerate salt stress antibiotic resistance.We four NaCl concentrations ranging 0.1%, 1%, 3% 5% liquid media plates, moreover we 24 disks determine resistance or sensitive among...
The potency of three chemical compounds as resistance inducer in tomato plants against root-knot nematode (Meloidogyne incognita) were evaluated using split root system technique.Salicylic acid (SA), Ascorbic (AS) and Dipotassium hydrogen phosphate (DKP) was assessed at concentrations (10, 20 50 mM) the activity cytoplasmic peroxidase Phenol oxidase leaves measured.Results indicated that application these inducers significantly reduced all related parameters under greenhouse...
Plants can adapt to their surroundings by hosting beneficial bacteria that confer a selective advantage in stressful conditions. Endophytes are class of exist within the internal spaces plants and many species improve plant nitrogen use efficiency. Nitrogen is an essential macronutrient, often limiting factor growth, especially cereal crops such as maize. Every year farmers apply over 100 million metric tonnes synthetic fertilizer meet growing demand for stable food crops. Breeding efforts...

One billion people globally suffer from protein (amino acid) malnutrition. Grain legumes represent a solution. They recruit symbiotic rhizobia bacteria soil into root nodules, where the convert atmospheric nitrogen gas (N 2 ) ammonia (NH 3 which serves as building block for chlorophyll and protein. However, when legume species is newly introduced to region, yields can be low due incompatible rhizobia. Millions of subsistence farmers benefit inoculation with exotic bacteria, but many...
Abstract The present study aimed to isolate a Trichoderma species with dual action as plant growth promoter in conjunction antagonistic activity against the pathogen Colletotrichum lagenarium . Using internal transcribed spacer (ITS) sequences and inter simple sequence repeat markers (ISSR), eight strains of were identified, their diversity was studied. In addition, some promoters such indole acetic acid (IAA) element solubilization evaluated. Moreover, amylase, pectinase, cellulase,...
