Induction of Systemic Resistance by Trichoderma harzianum Isolates in Pistachio Plants in-Fected with Verticillium dahliae
Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...
متن کاملInduction of Systemic Resistance against Insect Herbivores in Plants by Beneficial Soil Microbes
Soil microorganisms with growth-promoting activities in plants, including rhizobacteria and rhizofungi, can improve plant health in a variety of different ways. These beneficial microbes may confer broad-spectrum resistance to insect herbivores. Here, we provide evidence that beneficial microbes modulate plant defenses against insect herbivores. Beneficial soil microorganisms can regulate hormo...
متن کاملInduction of systemic resistance by plant growth promoting rhizobacteria in crop plants against pests and diseases
Plant growth promoting rhizobacteria (PGPR) belonging to Pseudomonas spp. are being exploited commercially for plant protection to induce systemic resistance against various pests and diseases. Mixtures of di!erent PGPR strains have resulted in increased e$cacy by inducing systemic resistance against several pathogens attacking the same crop. Seed-treatment with PGPR causes cell wall structural...
متن کاملLong-term influence of biochar on native organic carbon mineralisation in a low-carbon clayey soil
Biochar can influence native soil organic carbon (SOC) mineralisation through "priming effects". However, the long-term direction, persistence and extent of SOC priming by biochar remain uncertain. Using natural (13)C abundance and under controlled laboratory conditions, we show that biochar-stimulated SOC mineralisation ("positive priming") caused a loss of 4 to 44 mg C g(-1) SOC over 2.3 year...
متن کاملPyrogenic carbon additions to soil counteract positive priming of soil carbon mineralization by plants
Important due to both its role in fire-affected ecosystems, and also its proposed intentional production and application for carbon (C) management, pyrogenic organic matter (PyOM) is thought to contain very stable forms of C. However, the mechanisms behind its interactions with non-PyOM soil organic C (SOC) remain speculative, with studies often showing short-term positive and then long-term ne...
