Although microbes have been shown to metabolize and drive the speciation of Cd under controlled conditions, regardless of the link between soil bacterial community (SBC) dynamics and Cd mobilization in the rhizosphere, only a few studies have addressed the relationship between soil bacterial community composition (SBCC) and Cd content in cacao seeds (Cd\n              <jats:sub>seed<\/jats:sub>\n              ). Therefore, this study aimed to explore the association between SBCC and different factors influencing the distribution of Cd across cacao crop systems. This study comprised 225 samples collected across five farms, where we used an amplicon sequencing approach to characterize the bacterial community composition. The soil Cd concentration alone (Cd\n              <jats:sub>soil<\/jats:sub>\n              ) was a poor predictor of Cd\n              <jats:sub>seed<\/jats:sub>\n              . Still, we found that this relationship was more apparent when the variation within farms was controlled, suggesting a role of heterogeneity within farms in modulating Cd translocation and, thus, seed Cd content. Our results provide evidence of the link between soil bacterial communities and the distribution of Cd across Colombian cacao crops, and highlight the importance of incorporating fine-spatial-scale studies to advance the understanding of factors driving Cd uptake and accumulation in cacao plants.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>Cadmium (Cd) content in cacao crops is an issue that generates interest due to the commercialization of chocolate for human consumption. Several studies provided evidence about the non-biological factors involved in its translocation into the cacao plant. However, factors related to this process, including soil bacterial community composition (SBCC), still need to be addressed. It is well known that soil microbiome could impact compounds\u2019 chemical transformation, including Cd, on the field. Here, we found the first evidence of the link between soil bacterial community composition and Cd concentration in cacao soils and seeds. It highlights the importance of including the variation of bacterial communities to assess the factors driving the Cd translocation into cacao seeds. Moreover, the results highlight the relevance of the spatial heterogeneity within and across cacao farms, influencing the variability of Cd concentrations.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1128\/spectrum.03363-23","type":"journal-article","created":{"date-parts":[[2024,5,30]],"date-time":"2024-05-30T13:01:51Z","timestamp":1717074111000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Association between bacterial community and cadmium distribution across Colombian cacao crops"],"prefix":"10.1128","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7026-6432","authenticated-orcid":true,"given":"Claudia","family":"Jaramillo-Mazo","sequence":"first","affiliation":[{"name":"Research Group in Biological Sciences and BioProcess (CIBIOP), School of Applied Sciences and Engineering, EAFIT University, Medell\u00edn, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Bravo","sequence":"additional","affiliation":[{"name":"Laboratory of Soil Microbiology &amp; Calorimetry, Corporaci\u00f3n Colombiana de Investigaci\u00f3n Agropecuaria AGROSAVIA, Mosquera, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz E.","family":"Guerra Sierra","sequence":"additional","affiliation":[{"name":"Research Group in Agro\u2013Environmental Biotechnology and Health (MICROBIOTA), Facultad de Ciencias Exactas, Naturales y Agropecuarias, Universidad de Santander, Bucaramanga, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9009-823X","authenticated-orcid":false,"given":"Javier C.","family":"Alvarez","sequence":"additional","affiliation":[{"name":"Research Group in Biological Sciences and BioProcess (CIBIOP), School of Applied Sciences and Engineering, EAFIT University, Medell\u00edn, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2019.05.001"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.3390\/agronomy10060806"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2021.146779"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.4236\/fns.2016.71005"},{"key":"e_1_3_5_7_2","first-page":"1","article-title":"Commission delegated regulation (EU)","volume":"442","author":"European Commission","year":"2021","unstructured":"European Commission. 2021.
