Biological Control and Plant Growth Promotion Properties of Volatile Organic Compound-Producing Antagonistic spp.

is environmentally vital due to their plant growth-promoting effects (such as enhancement of nutrients supply, suppression of plant pathogens, and promotion of plant defense). Biogenic volatile organic compounds (VOCs) are diverse chemical substances emitted by spp. The potential role of VOCs in biological control and plant growth promotion has recently been recognized.

Expression of SidD gene and physiological characterization of the rhizosphere plant growth-promoting yeasts.

There is increasing evidence that rhizosphere microbes contribute to the stress mitigation process, but the mechanisms of this plant-microbe interaction are not yet understood. Siderophores-producing microorganisms have been considered important for enhancing metal tolerance in plants. In this study, rhizosphere yeasts were isolated from wheat ( L.

Effect of Rosemary Essential Oil and VOCs on Pathogenic Fungi Responsible for Ginseng Root-rot Disease.

Rosemary essential oil was evaluated for antifungal potentiality against six major ginseng pathogens: , , , , , and . The in vitro fungicidal effects of two commonly used fungicides, namely mancozeb and fenhexamid, and the volatile organic compounds (VOCs) of T-403 on the mycelial growth were investigated. The results showed that rosemary essential oil is active against all of the pathogenic strains of ginseng root rot, whereas rosemary oil displayed high ability to inhibit the spp.

Zinc Ions Affect Siderophore Production by Fungi Isolated from the Rhizosphere.

Although siderophore compounds are mainly biosynthesized as a response to iron deficiency in the environment, they also bind with other metals. A few studies have been conducted on the impact of heavy metals on the siderophore-mediated iron uptake by microbiome. Here, we investigated siderophore production by a variety of rhizosphere fungi under different concentrations of Zn²⁺ ion.

Plant Growth-Promoting Rhizobacteria Improved Salinity Tolerance of and .

Salinity stress is an important environmental problem that adversely affects crop production by reducing plant growth. The impacts of rhizobacterial strains to alleviate salinity stress on the germination of and seeds were assessed using different concentrations of NaCl. Plant growth-promoting rhizobacteria (PGPR) strains were also examined to improve the early germination of Chinese cabbage seeds under normal conditions.
