“…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.…”

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.

“…2002). As Cd 2+ move into the cells, the production of reactive oxygen species (ROS) is induced damaging the normal physiological metabolism of cells, and the AsA-GSH is the major pathway for ROS scavenging (Gao et al 2023; Tang et al 2023). There is su cient evidence indicating that vacuolar compartmentation plays an indispensable role in metal detoxi cation in the hyperaccumulator plant (Zhao et al 2000;Shen et al 2002;Carrillo and Borthakur 2021).…”

Melatonin can alleviate cadmium (Cd) stress in plants, but the cellular-level mechanism remains unclear, particularly in relation to its impact on detoxification processes within the protoplast and vacuole of plants. The plant Solanum nigrum L. was selected to explore the Cd concentration on vacuolar compartmentalization in the leaf cell under the application of exogenous melatonin. The contents of total Cd, Cd2+, ascorbic acid-glutathione (AsA-GSH) and reactive oxygen species (ROS) were determined in protoplasts and vacuoles of leaf cells through subcellular separation. It was found that vacuolar compartmentalization is a dynamic strategy accompanied by the reasonable allocation and continuous consumption of related substances outside the vacuole. Melatonin promoted a more reasonable allocation of resources outside the vacuole to maintain homeostasis. These findings might have implications for understanding melatonin-mediated cellular tolerance mechanisms and instructing the genetic ways to devise more ideal hyperaccumulator plants.
