Back to the roots: revealing beneficial interactions between the rhizosphere microbiome and wild wheat. Repositório Alice
ROSSMANN, M.; PÉREZ-JARAMILLO, J. E.; CHIARAMONTE, J. B.; KAVAMURA, V. N.; DUMACK, K.; FIORE-DONNO, A. M.; MENDES, L. W.; BONKOWSKI, M.; MAUCHLINE, T.; RAAIJMAKERS, J. M.; MENDES, R..
Domestication of plants may have impacted the interactions between plants and their rhizosphere microbiome. Considering that plants rely on the rhizosphere microbiome for functions related with plant growth, nutrition and health, the objective of this work was to analyse the rhizosphere microbiome of wild relatives and modern varieties of wheat and to investigate whether wild relatives recruit a higher proportion of beneficial microbes than modern cultivars. By 16S-rRNA gene amplicon, ITS and 18SrRNA gene amplicon, we assessed the bacterial, fungal and cercozoa rhizosphere community composition of five modern cultivars and three wheat ancestors cultivated in forest and agricultural soils. Results revealed a pronounced soil type and rhizosphere effect on...

Breeding for resistance to soil-borne pathogen impacts rhizosphere microbiome functions in common bean. Repositório Alice
MENDES, L. W.; MENDES, R.; RAAIJMAKERS, J. M.; TSAI, S. M..
Over the past century, plant breeding programs have substantially improved plant growth and health, but have not yet considered the potential effects on the plant microbiome. Here, we conducted a metatranscriptome analysis to determine if and how breeding for resistance of common bean against the root pathogen Fusarium oxysporum (Fox) affected gene expression in the rhizobacterial community. Our data revealed that rhizobacterial community assembly of Fox-resistant and susceptible bean cultivars follows niche-based mechanisms, presenting lower diversity and distinct community structure compared to the bulk soil. The microbiome of the Fox-resistant bean cultivar presented a significantly higher expression of bacterial genes associated with nutrient...

Deciphering rhizosphere microbiome assembly of wild and modern common bean (Phaseolus vulgaris) in native and agricultural soils from Colombia. Repositório Alice
PEREZ-JARAMILLO, J. E.; HOLLANDER, M. de; RAMÍREZ, C. A.; MENDES, R.; RAAIJMAKERS, J. M.; CARRIÓN, V. J..
Abstract: Background: Modern crop varieties are typically cultivated in agriculturally well-managed soils far from the centers oforigin of their wild relatives. How this habitat expansion impacted plant microbiome assembly is not well understood. Results: Here, we investigated if the transition from a native to an agricultural soil affected rhizobacterial communityassembly of wild and modern common bean (Phaseolus vulgaris) and if this led to a depletion of rhizobacterialdiversity. The impact of the bean genotype on rhizobacterial assembly was more prominent in the agriculturalsoil than in the native soil. Although only 113 operational taxonomic units (OTUs) out of a total of 15,925 wereshared by all eight bean accessions grown in native and agricultural...

Effect of plant domestication on the rhizosphere microbiome of common bean (Phaseolus vulgaris) . Repositório Alice
PÉREZ-JARAMILLO, J. E.; MENDES, R.; RAAIJMAKERS, J. M..
Plant domestication was a pivotal achievement for human civilization and subsequent plant improvement increased crop productivity and quality. However, domestication also caused a strong reduction in the genetic diversity of modern cultivars compared to their wild relatives. It is known that plants rely, in part, on the rhizosphere microbial community for wreowth, development and tolerance to (a)biotic stresses. Hence, plant domestication events may have adversely affected the bacterial diversity of the rhizosphere of two wild relatives, three landraces and three modern cultivars of common bean (Phaseolus vulgaris). These different lines belong to the Mesoamerican bean gene pool of Colombia and were selected amongst more than 37,000 accessions kept in the...

Fungal invasion of the rhizosphere microbiome. Repositório Alice
CHAPELLE-PINEAU, E.; MENDES, R.; BAKKER, P. A. H. M.; RAAIJMAKERS, J. M..
The rhizosphere is the infection court where soil-borne pathogens establish a parasitic relationship with the plant. To infect root tissue, pathogens have to compete with members of the rhizosphere microbiome for available nutrients and microsites. In disease-suppressive soils, pathogens are strongly restricted in growth by the activities of specific rhizosphere microorganisms. Here, we sequenced metagenomic DNA and RNA of the rhizosphere microbiome of sugar beet seedlings grown in a soil suppressive to the fungal pathogen Rhizoctonia solani. rRNA-based analyses showed that Oxalobacteraceae, Burkholderiaceae, Sphingobacteriacea and Sphingomonadaceae were significantly overrepresented in the rhizosphere upon fungal invasion. Metatranscriptomics revealed...

Genome mining and metabolic profiling of the rhizosphere bacterium Pseudomonas sp. SH-C52 for antimicrobial compounds. Repositório Alice
VOORT, M. van der; MEIJER, H. J. G.; SCHMIDT, Y.; WATROUS, J; DEKKERS, E.; MENDES, R.; DORRESTEIN, P.C; GROSS, H.; RAAIJMAKERS, J. M..
Abstract: The plant microbiome represents an enormous untapped resource for discovering novel genes and bioactive compounds. Previously, we isolated Pseudomonas sp. SH-C52 from the rhizosphere of sugar beet plants grown in a soil suppressive to the fungal pathogen Rhizoctonia solani and showed that its antifungal activity is, in part, attributed to the production of the chlorinated 9-amino-acid lipopeptide thanamycin (Mendes et al., 2011). To get more insight into its biosynthetic repertoire, the genome of Pseudomonas sp. SH-C52 was sequenced and subjected to in silico, mutational and functional analyses. The sequencing revealed a genome size of 6.3 Mb and 5579 predicted ORFs. Phylogenetic analysis placed strain SH-C52 within the Pseudomonas corrugata...

Impact of plant domestication on rhizosphere microbiome assembly and functions. Repositório Alice
PÉREZ-JARAMILLO, J. E.; MENDES, R.; RAAIJMAKERS, J. M..
Abstract: The rhizosphere microbiome is pivotal for plant health and growth, providing defence against pests and diseases, facilitating nutrient acquisition and helping plants to withstand abiotic stresses. Plants can actively recruit members of the soil microbial community for positive feedbacks, but the underlying mechanisms and plant traits that drive microbiome assembly and functions are largely unknown. Domestication of plant species has substantially contributed to human civilization, but also caused a strong decrease in the genetic diversity of modern crop cultivars that may have affected the ability of plants to establish beneficial associations with rhizosphere microbes. Here, we review how plants shape the rhizosphere microbiome and how...

Impact of soil heat treatment on bacterial community reassembly in the rhizosphere. Repositório Alice
VOORT, M.; MENDES, R.; RAAIJMAKERS, J. M..
The rhizosphere microbiome offers a range of ecosystem services to the plant. Including nutrient acquisition, tolerance to abiotic stress and protection against diseases. Here we studied how heat treatment of soil disturbs the reassembly of the bacterial community in the rhizosphere and how this affects tolerance to pathogen infection. Using PhyloChip-based community profiling, we assessed the impact of 1-hour heat treatments of 50ºC or 80ºC on the bacterial community composition in the rhizosphere of sugar beet seedlings grown in a soil that is naturally suppressive to the soil-borne fungus Rhizoctonia solani. The heat disturbance caused significant increase of alpha diversity and led to a partial (50ºC) or complete (80ºC) loss of protection against...

Mining of the endophytic microbiome for novel biosynthetic genes and antifungal metabolites. Repositório Alice
CARRION, V. J.; PÉREZ-JARAMILLO, J.; CORDOVEZ, V.; HOLLANDER, M. de; TRACANNA, V.; MENDES, L. W.; MENDES, R.; MEDEMA, M. H.; RAAIJMAKERS, J. M..
Endophytic microbes have been proposed to contribute to a range of plant support functions, including nutrient acquisition and disease protection. To date, the molecular mechanisms underlying disease protection in the endosphere have only been studied for individual culturable organisms. Here, we conducted a systematic microbiome-wide perspective on the taxonomic diversity and functional potential of the endophytic microbiome of plants grown in an agricultural soil that is naturally suppressive to damping-off disease caused by the fungal root pathogen Rhizoctonia solani. Metagenomic analyses showed an enrichment of Burkholderiaceae, Chitinophagaceae and Xanthomonadaceae in the endosphere of plants grown in disease-suppressive soil challenged with the...

Resistance breeding of common bean shapes the physiology of the rhizosphere microbiome. Repositório Alice
MENDES, L. W.; CHAVES, M. G. de; FONSECA, M. de C.; MENDES, R.; RAAIJMAKERS, J. M.; TSAI, S. M..
Abstract: The taxonomically diverse rhizosphere microbiome contributes to plant nutrition, growth and health, including protection against soil-borne pathogens. We previously showed that breeding for Fusarium-resistance in common bean changed the rhizosphere microbiome composition and functioning. Here, we assessed the impact of Fusarium-resistance breeding in common bean on microbiome physiology. Combined with metatranscriptome data, community-level physiological profiling by Biolog EcoPlate analyses revealed that the rhizosphere microbiome of the Fusarium-resistant accession was distinctly different from that of the Fusarium-susceptible accession, with higher consumption of amino acids and amines, higher metabolism of xylanase and sialidase, and higher...

The spermosphere effect: building up plant microbiome assembly. Repositório Alice
PÉREZ-JARAMILLO, J. E.; CARRION, V. J.; HOLLANDER, M. de; MENDES, R.; RAAIJMAKERS, J. M..
Plants have a significant influence on the diversity and activity of soil microbial communities. During imbibition and germination, plant seeds release chemically diverse exudates thereby promoting microbial activity in the zone surrounding the seed, also referred to as the spermosphere. To date, little is known about the diversity and activities of microbial communities in the spermosphere and how this short-lived plant developmental stage affects microbiome assembly. Here, we deciphered the magnitude of the spermosphere effect for two different food crops, i.e. tomato and bean. More specifically, we investigated if a plant genotype-dependent influence is discernible in the spermosphere and to what extent the spermosphere microbiome relates to the...
