Local adaptation to mercury contamination by nitrogen-fixing rhizobia is driven by horizontal gene transfer, copy number, and enhanced gene expression

This study identifies that horizontal gene transfer, copy number, and enhanced expression of the Mer operon confer mercury tolerance in rhizobia, with implications for plant-metal interactions.

Correlative single-cell hard X-ray tomography and X-ray fluorescence imaging

This paper develops a method to combine single-cell X-ray tomography and fluorescence imaging to study cellular structures and chemical element distributions.

Genome-wide association study reveals complex genetic architecture of cadmium and mercury accumulation and tolerance traits in Medicago truncatula

Experimental and field data support habitat expansion of the allopolyploid Arabidopsis kamchatica owing to parental legacy of heavy metal hyperaccumulation

The paper shows that the allopolyploid Arabidopsis kamchatica retains hyperaccumulation traits from its parent A. halleri, enabling it to expand into heavy metal-rich habitats.

Patterns of polymorphism, selection and linkage disequilibrium in the subgenomes of the allopolyploid Arabidopsis kamchatica

The paper analyzes polymorphism, selection, and linkage disequilibrium in the subgenomes of Arabidopsis kamchatica, finding reduced purifying selection and increased adaptive substitutions compared to parental species.
