Responses of Rhizosphere Bacterial and Fungal Communities to the Long-Term Continuous Monoculture of Water Oat

Abstract: As an cultivated aquatic vegetable, the long-term continuous monocropping of water oat results in the frequent occurrence of diseases, the deterioration of ecological system and decreased quality of water oat. In this study, real-time quantitative PCR (qPCR) and Illumina high-throughput sequencing were used to determine the dynamic changes in bacterial and fungal communities in rhizosphere soil under continuous cropping of water oat for 1, 5, 10, 15 and 20 years (Y1, Y5, Y10, Y15 and Y20), and soil properties … Show more

“…Among these, the heightened activity of acid phosphatase was attributed to decreased soil pH [38], while the implications on urease activity remain ambiguous. The results of this research show a positive correlation between the age of the Eucalyptus plantation and the activity of soil sucrase, which is consistent with the findings of Wu et al [39]. Soil catalase protects plants from the phytotoxic effects of hydrogen peroxide by breaking it down [40].…”

“…Sequence denoising or operational taxonomic units (OTUs) clustering was performed using either the QIIME2 DADA2 analysis process or V-search software analysis process. The relative abundance of soil microbes was determined at the taxonomic level of phylum, and the microbial diversity indices were calculated, including the Chao1 index, Ace index, Shannon index, and Evenness index (Wu et al, 2022;Yao et al, 2022).…”

“…The response of soil bacterial and fungal communities and of soil biochemical variables to long-term continuous monocropping (from 5 to 20 yrs) of water oats was examined by Wu et al [ 9 ]. The soil biochemical properties and the activity of soil enzymes were higher at 5 to 10 yrs of cultivation and then declined.…”

“…This Special Issue, entitled “Soil microbial communities and ecosystem functions”, contains four original contributions focusing on the changes in microbial communities’ composition and diversity in relation to soil chemical variables and/or enzyme activities, which are used as proxies of soil functionality, and a review article discussing the pitfalls of soil metagenomics. In the included research articles, microbial communities are considered under conditions of tillage/no tillage [ 7 ], organic fertilizers’ legacy [ 8 ], continuous cultivation [ 9 ], and fire [ 10 ]. Importantly, the authors analyzed not only the quantitative aspects of the community under consideration, such as biomass, abundance, and diversity, but they also discussed the qualitative aspects resulting from the network of correlations among the members of the community, such as network connectance, centrality, betweenness, and keystone taxa.…”
