Assessment of soil quality in an arid and barren mountainous of Shandong province, China.

Forest soils are important components of forest ecosystems, and soil quality assessment as a decision-making tool to understand forest soil quality and maintain soil productivity is essential. Various methods of soil quality assessment have been developed, which have occasionally generated inconsistent assessment results between soil types. We assessed the soil quality of five communities (herb, shrub, Quercus acutissima, Pinus thunbergii, and Q.

The Impact of the Soil Survival of the Pathogen of Wilt on Soil Nutrient Cycling Mediated by Microorganisms.

wilt of in the greenhouse is one of the most severe crop diseases in Shandong Province, P.R. China.

Transcription Factor : A Requirement for Growth, Pathogenicity, Development, and Maintenance of Cell Wall Integrity in .

Apple canker disease, caused by , is one of the most serious apple tree diseases in China. is an important transcription factor that acts on the cyclic adenosine signaling pathway (cAMP/PKA), regulating the growth, development, morphological differentiation, and pathogenic forces of the pathogen. We perform transcriptome analysis of the deletion mutant and the wild-type strain 11-175 and identify a significantly differentially expressed gene, , a zinc finger motif transcription factor in .

The Regulation of the Growth and Pathogenicity of by the Carbon Metabolism Repressor .

Carbon catabolite repression (CCR) is a very important mechanism for efficient use of carbon sources in the environment and is necessary for the regulation of fungal growth, development, and pathogenesis. Although there have been extensive studies conducted regarding this mechanism in fungi, little is yet known about the effects of genes on . However, based on the results obtained in this study for the identification of the gene in , it was determined that the gene was expressed at all stages of fungal growth, with self-repression observed at the transcriptional level.

Effects of nitrogen input on soil bacterial community structure and soil nitrogen cycling in the rhizosphere soil of L.

L., goji berry, is a precious traditional Chinese medicine and it is homology of medicine and food. Its growth is heavily dependent on nitrogen.

Mechanisms in Growth-Promoting of Cucumber by the Endophytic Fungus Strain ND35.

Endophytic fungi are effective in plant growth and development by secreting various kinds of plant hormones and nutrients. However, the cellular and molecular interactions between the endophytic fungi and plant growth-promoting have remained less explored. The present study was designed to explore the effects of the infection and colonization events of strain ND35 on cucumber growth and the expression pattern of some metabolically important genes in development of the cucumber radicle.

Isolation and Identification of sp. Strain Q2 and Its Biocontrol Mechanisms Involved in the Control of Wilt.

wilt is an important disease of many food crops and often causes serious damages to yield and food quality. Consequently, numerous studies mainly focused on exploring the control strategy for as well as the mechanism of interaction between the and other beneficial soil microorganisms. In this study, we have screened and identified an efficient biocontrol strain from the soil with infection of f.

[Biocontrol potential of and its regulation on soil microbial community].

strain Q2 is a kind of beneficial microbe originally separated from the rhizosphere of healthy cucumber. In this study, we evaluated the biocontrol potential of strain Q2 against four soil-borne diseases by plate confrontation culture, potting in the greenhouse. We further estimated the control efficacy of strain Q2 combined metam-sodium fumigation against wilt of bitter gourd in the field.

[Isolation, screening and identification of anantagonistic actinomycetes to control wilt of ].

f. sp. was used as the target pathogenic fungus to screen actinomycetes that were isolated from rhizosphere soil of by confrontation culture and antifungal tests of fermentation filtrate.
