ABSTRACT Inoculation of plant-beneficial microbes into agricultural soils can improve crop growth, but such outcomes depend on microbial survival. Here, we assessed how exposure to prior environmental conditions impacts in-soil fitness, particularly focusing incubation in liquid culture as an unavoidable phase inoculant production and pre-incubation target a potential method performance. We conducted experimental evolution phosphorus-solubilizing bacterial species, Priestia megaterium , (i) soil only, (ii) media (iii) followed by media, using population metagenomic sequencing track mutations over time. Several typical vitro evolutionary phenomena were observed media-incubated populations, including clonal interference, genetic hitchhiking, mutation parallelism between replicate the sporulation transcription factor spo0A . Liquid populations also developed clear fitness reduction compared ancestral isolate. However, soil-incubated grew slowly, experienced far fewer generations despite longer absolute time, accumulated minimal mutational changes. Correspondingly, did not display improved survival isolate their soils, though there appear be minor reductions unfamiliar soil. This work demonstrates that adaptation and/or native impact new more complex real-world habitats does closely resemble media. IMPORTANCE Innovative solutions are needed address emerging challenges agriculture while reducing its footprint. Management microbiomes could contribute this effort, plant growth-promoting microorganisms provide key ecosystem services support crops. Yet, inoculating beneficial farm yields unreliable results. require greater knowledge ecology these taxa functioning sustainable agroecosystems.

Global warming is expected to have a direct impact on plant disease patterns in agro-eco-systems. However, few analyses report the effect of moderate temperature increase severity due soil-borne pathogens. For legumes, modifications root plant-microbe interactions either mutualistic or pathogenic climate change may dramatic effects. We investigated increasing quantitative resistance Verticillium spp., major fungal pathogen, model legume Medicago truncatula and crop M. sativa. First, twelve strains isolated from various geographical origin were characterized with regard their vitro growth pathogenicity at 20°C, 25°C 28°C. Most them exhibited as optimum for parameters, between 20°C pathogenicity. Second, V. alfalfae strain was adapted higher by experimental evolution, i.e. three rounds UV mutagenesis selection 28°C susceptible genotype. Inoculation monospore isolates these mutants resistant accessions revealed that they all more aggressive than wild type strain, some had acquired ability cause Third, one mutant selected further studies response sativa (cultivated alfalfa). The seven contrasted genotypes alfalfa varieties inoculation followed using colonization, With temperature, lines switched (no symptoms, no fungus tissues) tolerant symptoms but into phenotypes, partially susceptible. Further greenhouse evidence reduction fitness lines. thus are affected anticipated global warming, trends towards increased susceptibility larger virulence hot-adapted strains. New threats pathogens, possibly wider host range aggressiveness, might occur.

Invading pathogens interact with plant-associated microbial communities, which can be altered under the pressure of pathogen infection. Limited information exists on plant–microbe interactions occurring during natural outbreaks in agricultural fields. Taproot decline (TRD) soybean is an emerging disease caused by Xylaria necrophora. TRD occurrence and yield loss associated are outstanding issues production. We applied nuclear ribosomal DNA Internal Transcribed Spacers 16S rRNA gene taxonomic marker sequencing to define composition fungal bacterial communities healthy diseased roots collected from Mississippi Delta. The plant compartment was a significant factor regulating diversity, followed status plant. impacted root endophytes, causing imbalances; at intermediate advanced stages TRD, X. necrophora decreased mycobiome whereas it increased microbiome richness. Networks co-occurrence co-exclusion relationships revealed direct indirect associations among taxa identified hubs potential roles assembling TRD-affected biomes.

Summary Hosts and pathogens typically engage in a coevolutionary arms race. This also applies to phytopathogenic powdery mildew fungi, which can rapidly overcome plant resistance perform host jumps. Using experimental evolution, we show that the pathogen Blumeria hordei is capable of breaking agriculturally important broad‐spectrum conditioned by barley loss‐of‐function mlo mutants. Partial virulence evolved B. isolates correlated with distinctive pattern adaptive mutations, including small‐sized ( c. 8–40 kb) deletions, one linked de novo insertion transposable element. Occurrence mutations associated transcriptional induction effector protein‐encoding genes absent ‐avirulent on mutant plants. The detected mutational spectrum comprises same loci at least two independently isolated ‐virulent isolates, indicating convergent multigenic evolution. events emerged part early (within first five asexual generations) during likely generating founder population incipient was later stabilized additional events. work highlights rapid dynamic genome evolution an obligate biotrophic transposon‐enriched genome.
