Biological control is considered as a promising alternative to pesticide and plant resistance manage diseases, but better understanding of the interaction its natural societal functions necessary for endorsement. The introduction biological agents (BCAs) alters among plants, pathogens, environments, leading physical cascades that influence pathogen fitness, health, ecological function. These interrelationships generate landscape tradeoffs social control, comprehensive evaluation benefits costs across farmer perspectives required ensure sustainable development deployment approach. Consequently, there should be shift disease philosophy from single concept only concerns crop productivity multifaceted concerning productivity, function, acceptability, economical accessibility. To achieve these goals, attempts make develop "green" BCAs used dynamically synthetically with other approaches in an integrated management scheme, evolutionary biologists play increasing role formulating strategies.

Antimicrobial resistance is a serious threat to global public health, but little known about the effects of microbial control on microbiota and its associated resistome. Here we compare present surfaces clinical settings with other built environments. Using state-of-the-art metagenomics approaches genome plasmid reconstruction, show that increased confinement cleaning loss diversity shift from Gram-positive bacteria, such as Actinobacteria Firmicutes, Gram-negative Proteobacteria. Moreover, microbiome highly maintained environments has different resistome when compared environments, well higher in genes.

Biosurfactants in Plant Protection Against Diseases: Rhamnolipids and Lipopeptides Case Study

Frontiers in Bioengineering and Biotechnology, Journal Year: 2020, Volume and Issue: 8

Published: Sept. 8, 2020

Biosurfactants are amphiphilic surface-active molecules that produced by a variety of microorganisms including fungi and bacteria. Pseudomonas, Burkholderia Bacillus species known to secrete rhamnolipids lipopeptides used in wide range industrial applications. Recently, these compounds have been studied context plant-microbe interactions. This mini-review describes the direct antimicrobial activities against plant pathogens. We also provide current knowledge on how stimulate immune system leading resistance phytopathogens. Given their low toxicity, high biodegradability ecological acceptance, we discuss possible role biosurfactants as alternative strategies reduce or even replace pesticide use agriculture.

Plant-associated microorganisms are involved in important functions related to growth, performance and health of their hosts. Understanding modes action is for the design promising microbial inoculants sustainable agriculture. able interact with hosts often exert specific toward potential pathogens; underlying vitro interactions well studied. In contrast, situ effects inoculants, especially impact on plant indigenous microbiome was mostly neglected so far. Recently, research has revolutionized our understanding plants as coevolved holobionts but also microbiome-inoculant interactions. Here we disentangle point out following types modulations: (i) transient shifts, (ii) stabilization or increase diversity, (iii) evenness, (iv) restoration a dysbiosis/compensation reduction pathogen-induced shift, (v) targeted shifts beneficial members microbiota, (vi) suppression pathogens.
