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...

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...

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...
