“…Besides antifungal activity, comparative metatranscriptomics of the rhizosphere microbiome of different plants, including oat and avenacin‐deficient oat mutants, suggest that avenacins may have a broader role in impacting the eukaryotic community . Another example of triterpene glycosides affecting the eukaryotic organisms are the allelopathic effects of autotoxic ginsenosides produced by Panax notoginseng .

“…Due to their low volatility, some compounds exuded by plants can be deposited in the soil and confer long-lasting impact on the soil-dwelling communities. 27 The diterpene momilactones A and B were first isolated from the seed husk of rice and reported to inhibit the growth of rice roots at less than 100 ppm. 35 Momilactones are also phytoalexins produced by rice in response to pathogen attack or when elicited with chitin oligosaccharide, components of fungal cell wall that mimic fungal attacks.…”

Plants are sessile organisms that have evolved various mechanisms to adapt to complex and changing environments. One important feature of plant adaption is the production of specialised metabolites. Terpenes are the largest class of specialised metabolites, with over 80 000 structures reported so far, and they have important ecological functions in plant adaptation. Here, we review the current knowledge on plant terpenes that mediate below‐ground interactions between plants and other organisms, including microbes, herbivores and other plants. The discovery, functions and biosynthesis of these terpenes are discussed, and prospects for bioengineering terpenoids for plant protection are considered. © 2019 The Authors.

“…Various studies indicated that consecutive monoculture of medicinal plants led to the accumulation of toxic compounds in soil, such as microbial secondary metabolites, autotoxins released by plant roots, and so on [43,44,45]. In this study, it was found that the percentage of reads categorized to penicillin and cephalosporin biosynthesis (ko00311) was significantly higher in CM than in NP (Figure S9).…”

Consecutive monoculture of Rehmannia glutinosa, highly valued in traditional Chinese medicine, leads to a severe decline in both quality and yield. Rhizosphere microbiome was reported to be closely associated with the soil health and plant performance. In this study, comparative metagenomics was applied to investigate the shifts in rhizosphere microbial structures and functional potentials under consecutive monoculture. The results showed R. glutinosa monoculture significantly decreased the relative abundances of Pseudomonadaceae and Burkholderiaceae, but significantly increased the relative abundances of Sphingomonadaceae and Streptomycetaceae. Moreover, the abundances of genera Pseudomonas, Azotobacter, Burkholderia, and Lysobacter, among others, were significantly lower in two-year monocultured soil than in one-year cultured soil. For potentially harmful/indicator microorganisms, the percentages of reads categorized to defense mechanisms (i.e., ATP-binding cassette (ABC) transporters, efflux transporter, antibiotic resistance) and biological metabolism (i.e., lipid transport and metabolism, secondary metabolites biosynthesis, transport and catabolism, nucleotide transport and metabolism, transcription) were significantly higher in two-year monocultured soil than in one-year cultured soil, but the opposite was true for potentially beneficial microorganisms, which might disrupt the equilibrium between beneficial and harmful microbes. Collectively, our results provide important insights into the shifts in genomic diversity and functional potentials of rhizosphere microbiome in response to R. glutinosa consecutive monoculture.

Continuous‐cropping tobacco caused variance of chemical properties and structure of bacterial network in soils

Continuous cropping of the same crop leads to land degradation. This is also called the continuous-cropping obstacle. Here, we investigated how long-term continuous cropping of tobacco influences soil biochemical properties and bacterial networks in the mountain lands of China. Two different fields were sampled: one with 25 years of continuous cropping tobacco and one with noncontinuous cropping tobacco. Soil chemical and biological properties were measured including available phosphorus and potassium, soil organic matter, pH, alkali-hydrolysable nitrogen, micronutrients contents, and activity of urease, catalase, invertase, and phosphatase as well as tobacco agronomic characteristics. Bacterial communities of the two different soils were sequenced by metabarcoding of the 16S ribosomal RNA, and, with these data, network analysis was done. Soil chemical properties and tobacco agronomical properties were negatively affected by the continuous-cropping obstacle, and this treatment has a less complex network (less modules, nodes, and connectivity) than the soil with noncontinuous cropping treatment. For continuous cropping, there were less generalists, which were key species that connect network, than noncontinuous cropping.Moreover, the taxonomic composition of bacterial network was different in the two different treatments. In the continuous-cropping network, 40% nodes had negative interactions, suggesting that more competition or antagonism existed among bacterial species. It concluded that continuous cropping has a detrimental effect on soil chemical and that the bacterial network properties under continuous cropping are more sensitive to soil variables (so more unstable and inefficient) because there are less bacterial species that interact each other and this is due to limited nutrients or excessive toxic nutrient.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
