“…This study expands the understanding of the genetic diversity and population structure of B. pilosa , a species identified as a weed [ 21 ], with various food uses and in traditional medicine [ 2 , 22 ]. Although its role in phytoremediation, especially in the absorption of cadmium [ 10 , 22 ], and its therapeutic potential are well documented [ 7 ], detailed genomic research is scarce. Our work endeavors to fill this gap by exploring the genetics of B. pilosa and scrutinizing the interactions between soil microorganisms, the plant, and its environment.…”

“…Despite being considered a weed in the main crops, various studies have been conducted on the microfauna associated with its rhizosphere. This attention has paved the way for its utilization in phytoremediation processes for soils contaminated by cadmium, owing to its remarkable capacity for metal adsorption facilitated by the presence of Lysobacter [ 10 ].…”

Bidens pilosa L., native to South America and commonly used for medicinal purposes, has been understudied at molecular and genomic levels and in its relationship with soil microorganisms. In this study, restriction site-associated DNA markers (RADseq) techniques were implemented to analyze genetic diversity and population structure, and metabarcoding to examine microbial composition in soils from Palmira, Sibundoy, and Bogotá, Colombia. A total of 2,984,123 loci and 3485 single nucleotide polymorphisms (SNPs) were identified, revealing a genetic variation of 12% between populations and 88% within individuals, and distributing the population into three main genetic groups, FST = 0.115 (p < 0.001) and FIT = 0.013 (p > 0.05). In the soil analysis, significant correlations were found between effective cation exchange capacity (ECEC) and apparent density, soil texture, and levels of Mg and Fe, as well as negative correlations between ECEC and Mg, and Mg, Fe, and Ca. Proteobacteria and Ascomycota emerged as the predominant bacterial and fungal phyla, respectively. Analyses of alpha, beta, and multifactorial diversity highlight the influence of ecological and environmental factors on these microbial communities, revealing specific patterns of clustering and association between bacteria and fungi in the studied locations.
