“…The aromatic volatiles, especially the phenylpropanoids, are reported to bind to proteins in the cell membranes, thereby changing their conformation (Bennis, Chami, Chami, Bouchikhi, & Remmal, ). Similarly, GLVs, such as ( E )‐2‐hexenal bind to microbial proteins secreted into the extracellular space, rendering them non‐functional (Myung, Hamilton‐Kemp, & Archbold, ), whereas indolic volatiles are known to disrupt the integrity of the cytoskeleton (Mei et al, ). In addition, plant volatiles can cause programmed cell death (Chen, Zheng, et al, ), disrupt the respiratory electron chain (Fry & Munch, ), inhibit specific enzymes (Wendakoon & Sakaguchi, ), and interrupt communication between microbial cells such as that in bacterial quorum sensing (Joshi et al, ).…”

Plants emit a large variety of volatile organic compounds during infection by pathogenic microbes, including terpenes, aromatics, nitrogen-containing compounds, and fatty acid derivatives, as well as the volatile plant hormones, methyl jasmonate, and methyl salicylate. Given the general antimicrobial activity of plant volatiles and the timing of emission following infection, these compounds have often been assumed to function in defence against pathogens without much solid evidence. In this review, we critically evaluate current knowledge on the toxicity of volatiles to fungi, bacteria, and viruses and their role in plant resistance as well as how they act to induce systemic resistance in uninfected parts of the plant and in neighbouring plants. We also discuss how microbes can detoxify plant volatiles and exploit them as nutrients, attractants for insect vectors, and inducers of volatile emissions, which stimulate immune responses that make plants more susceptible to infection. Although much more is known about plant volatile-herbivore interactions, knowledge of volatilemicrobe interactions is growing and it may eventually be possible to harness plant volatiles to reduce disease in agriculture and forestry. Future research in this field can be facilitated by making use of the analytical and molecular tools generated by the prolific research on plant-herbivore interactions.

“…Zhang et al [28] reported that melatonin resulted in a branched hyphae, blunt hyphal tip, and a decrease of lipid droplets in P. infestans. Benzothiazole is an antimicrobial secondary metabolite volatilized by microbes, and may act as potential leading compound for the development of new oomycete fungicides [29]. Abnormal swellings and branches were developed along the hyphae after exposure to benzothiazole, and the polarized distribution of newly synthesized walls was also disrupted.…”

“…The down-regulation of the rate-limiting enzyme 6-phosphofructokinase and fatty acid synthase would reduce or suppress the carbohydrate and lipid metabolism. Mei et al [29] applied the combination of transcriptomic and proteomic approaches to explore the novel antifungal mechanisms of Benzothiazole against P. capsici . A total of 1,071 DEGs were identified, and they were related to the biological regulation, growth, organelle part, and cell part, and the single-organism process was down-regulated.…”

With the improper application of fungicides, Phytophthora sojae begins to develop resistance to fungicides, and biological control is one of the potential ways to control it. We screened two strains of Bacillus; Bacillus amyloliquefaciens JDF3 and Bacillus subtilis RSS-1, which had an efficient inhibitory effect on P. sojae. They could inhibit mycelial growth, the germination of the cysts, and the swimming of the motile zoospores. To elucidate the response of P. sojae under the stress of B. amyloliquefaciens and B. subtilis, and the molecular mechanism of biological control, comparative transcriptome analysis was applied. Transcriptome analysis revealed that the expression gene of P. sojae showed significant changes, and a total of 1616 differentially expressed genes (DEGs) were detected. They participated in two major types of regulation, namely “specificity” regulation and “common” regulation. They might inhibit the growth of P. sojae mainly by inhibiting the activity of ribosome. A pot experiment indicated that B. amyloliquefaciens and B. subtilis enhanced the resistance of soybean to P. sojae, and their control effects of them were 70.7% and 65.5%, respectively. In addition, B. amyloliquefaciens fermentation broth could induce an active oxygen burst, NO production, callose deposition, and lignification. B. subtilis could also stimulate the systemic to develop the resistance of soybean by lignification, and phytoalexin.

“…Last, a likely hypothesis is that maize root exudates contain molecules that may be toxic to Sonchus associated fungi or would destabilize the symbiotic associations. Several studies aiming at de ning the composition of maize root exudates revealed that benzothiazole (BZO), an aromatic heterocyclic compound, as well as benzoxazinoids, like 2,4-Dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and its degradation product 6-methoxy-benzoxazolin-2(3H)-one (MBOA) possess antimicrobial activity against plant pathogenic fungi and oomycetes (Yang et al 2014), (Mei et al 2019). Other molecules, like phenolic acids, were found in root exudates and have a strong antimicrobial activity against these microbial pathogens (Zhu and Morel 2019), (Zhang et al 2020).…”

Intercropping or assistant-endophytes has been proven to promote phytoremediation capacities of hyperaccumulators and to enhance their tolerance to heavy metals (HM) stress. We initially showed that intercropping with maize improved the remediating properties of the hyperaccumulator Sonchus asper (L.) Hill grown in HM contaminated soils, accompanied by an excluder - to- hyperaccumulator switched mode of action towards lead. To characterize molecular events underlying this shift in lead extraction strategy, we conducted an RNA-Seq analysis on Sonchus roots grown in intercropping or monoculture. We show that intercropping only slightly affects the S. asper transcriptome, but dramatically impacts the expression of root associated microbial genomes. Further, intercropping triggers a severe reshaping of endophytic communities which accompanies a “root-to-shoot” transition of lead sequestration and improved phytoremediation capacities of S. asper. This study provides the clue that a unitive network of plant- microbial -plant interactions may participate to the phytoremediation abilities of hyperaccumulator plants and paves the path for innovative cultural practices aiming to cure polluted soils.
