چکیده

Ethylene-producing strains of Penicillium cyclopium and P. crustosum were isolated from soil. These isolates produced ethylene on a variety of carbon growth substrates including phenolic acids. The quantities of ethylene produced on the various substrates varied, and the subtrate-ethylene prosuction pattern for P. cyclopium strains differed significantly from that of P. crustosum strains.

Bioremediation of MEG, DEG, and TEG: Potential of Burhead Plant and Soil Microorganisms

Abstract—The aim of this work was to investigate the potential of soil microorganisms and the burhead plant, as well as the combination of soil microorganisms and plants to remediate monoethylene glycol (MEG), diethylene glycol (DEG), and triethylene glycol (TEG) in synthetic wastewater. The result showed that a system containing both burhead plant and soil microorganisms had the highest effici...

Measurement of ACC-Deaminase Production in Halophilic, Alkalophilic and Haloalkalophilic Bacterial Isolates in Soil

Strains with 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity can cause plant growth on stress condition. In the presence of bacteria with the ability of ACC deaminase production in the rhizosphere, it is possible to convert the ethylene precursor (ACC) to α-ketobutyrate  and ammonium, reducing the ethylene levels in host plants. In order to measure the power and level of A...

Response of Etiolated Pea Seedlings and Cotton to Ethylene Produced from L-methionine by Soil Microorganisms

The presence of a suitable substrate(s) in soil may release physiologically active concentration of a plant hormone ethylene (C2H4) as a result of microbial activity. We isolated three strains of fungi (Aspergillus clavatus, Penicillium commure and Thamridium elegans), from the maize rhizosphere soil, capable of producing C2H4 in the soil from L-methionine (10 mmol l). The plate and soil inocul...

Leaf gas exchange and growth of flood-tolerant and flood-sensitive tree species under low soil redox conditions.

Seedlings of Taxodium distichum L., Quercus lyrata Walt. and Q. falcata var. pagodaefolia Ell. were grown for 22 days in a rhizotron system providing two soil redox potential regimes, +170 mV (low Eh) and +560 mV (high Eh). Leaf chlorophyll concentration and gas exchange, root alcohol dehydrogenase (ADH) activity, root and leaf ethylene production, and growth and biomass partitioning were measu...

Induction 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...
