“…Plants can influence soil properties and soil organisms via releasing low-molecular mass compounds(sugars, amino acids and organic acids) and dead roots, in turn modifying plant performance through mutualistic interactions, nutrition availability, or pathogenic activity, etc. (Berg and Smalla, 2009;Jones et al, 2009;Huang et al, 2013). Although the reasons for poor growth and reduced yields caused by Table 2; ‡Reference soil collected from a neighboring field with the same soil type but without growing Chuju Table 2 continuous monocropping are complicated and have not been clearly defined, they may be summarized as follows:…”

. Bio-organic fertilizer promotes plant growth and yield and improves soil microbial community in continuous monoculture system of Chrysanthemum morifolium cv. Chuju. AbstractChuju, a cultivar of Chrysanthemum morifolium, has been growing for both drink and medicinal uses for hundreds of years in China. In recent years, however, continuous monoculture of Chuju has caused declines in growth and yields. In this study, we investigated the plant growth and yields, soil microbial community composition dynamics, and the improvements of bio-organic fertilizer on plant growth and yield in Chuju continuous cropping systems. Results showed that the yield of Chuju flowers was decreased by 11-37%, but Fusarium oxysporum and total fungus populations were respectively increased by 34-79% and 53-107% in soils continuously monocultured with Chuju for two to four years, as compared to those for one year. Bio-organic fertilizer significantly reduced F. oxysporum population and the ratio of F. oxysporum to total fungus population, but enhanced shoot biomass, flower diameter, and flower yields, in comparison with synthetic fertilizer. These results indicate that bio-organic fertilizer could be used to alleviate soil problems and to sustain crop production in continuous cropping systems of Chuju.

“…The exact causes of soil sickness represent a continued focus of research activity (Mazzola and Manici 2012;Huang et al 2013). Various factors, such as the accumulation of phytotoxins, ion imbalances in the soil, or pathogen abundance, have been suggested as possible causes of this problem, yet differences exist relative to the functional diseasecausing agents (Rumberger et al 2007; Mazzola and Manici Electronic supplementary material The online version of this article (doi:10.1007/s00374-015-1038-8) contains supplementary material, which is available to authorized users.…”

Cotton yield and quality have been severely compromised by soil sickness throughout the primary cottongrowing regions of China. The aim of this study was to gain insight into the role of rhizosphere microbial community in governing soil sickness of cotton. Plant growth, disease resistance, root exudates, and the composition of the rhizosphere microbial community of cotton were analyzed in two different (4-and 15-year) monocropped soils and in a fallow agricultural soil (control). The monocropped soils significantly influenced cotton growth and root exudates and reduced soil suppressiveness to Fusarium wilt in bioassay experiments. Additionally, pyrosequencing of the whole internal transcribed spacers (ITS1 and ITS2) and 16S rRNA gene amplicons demonstrated clear variations in the microbial composition of cotton rhizosphere between monocropped rhizosphere soils and control soil. Specifically, monocropped soils were characterized by an increase in the abundance of fungal pathogens, including Fusarium oxysporum f. sp. vasinfectum and Verticillium dahliae, relative to the rhizosphere of control soil. Some plant-beneficial and disease-suppressive bacterial taxa, including Xanthomonadaceae, Comamonadaceae, Oxalobacteraceae, and Opitutaceae, were associated with healthy cotton. A significant correlation existed between the presence of certain amino acids (e.g., glutamic acid and alanine) and the above identified taxa, indicating that some constituents in root exudates influenced the microbial compositions of the cotton rhizosphere to manage the disease status of plant in monocropped soils. Collectively, these results suggest that pathogenic fungal build-up and a reduction in the abundance of beneficial rhizobacteria in the rhizosphere contribute to changes in soil suppressiveness to soil-borne pathogens in monocropped soils, resulting in an aggravated level of soil sickness.

-gang Xie (2015) Effect of 4-hydroxybenzoic acid on grape (Vitisvinifera L.) soil microbial community structure and functional diversity, Biotechnology & Biotechnological Equipment, 29:4, 637-645, DOI: 10.1080/13102818.2015 Phenolic compounds are considered to be an important autotoxic substances. The interactions between them and soil microbes are increasingly becoming a focus of the allelopathic research studies. In the present study, we have evaluated the effect of 4-hydroxybenzoic acid on soil microbial community structure and functional diversity. Bulk soil without grapevine cuttings (Group 1) and rhizosphere soil with Beta (Vitis riparia £ Vitis labrusca) grapevine cuttings (Group 2) were used as research subjects. The bacterial (16s rRNA) and fungal internal transcribed spacer regions community structures were obtained using a denaturing gradient gel electrophoresis and substrate utilization patterns were determined using Biolog EcoPlates. In this research, the results showed that the 4-hydroxybenzoic acid caused a shift in the soil bacterial and fungal community structures and changed the soil microbial functional diversity. The results also showed that the diversity of the microbial community structure and function differed between the two designated groups. The application of 4-hydroxybenzoic acid (1 and 2 mg/g) to the soil resulted in a greater decrease in the average diversity of the bacterial community structure in Group 2, compared to Group 1. Moreover, the average diversity of the fungal community structure in Group 2 became higher than that in Group 1. However, the bacterial and fungal community structural diversities increased with the application of 0.5 mg/g of 4-hydroxybenzoic acid. Thus, we concluded that both soil microbes and root exudates might be the recipients of 4-hydroxybenzoic acid.
