Population genomics reveals demographic history and climate adaptation in Japanese Arabidopsis halleri

This study uses population genomics to analyze climate adaptation and demographic history in Japanese Arabidopsis halleri, revealing genetic differentiation and selection signatures linked to climate variables.

The BRUTUS-LIKE E3 ligases BTSL1 and BTSL2 fine-tune transcriptional responses to balance Fe and Zn homeostasis

This study shows that loss-of-function of BTSL1 and BTSL2, which suppress iron uptake, confers zinc tolerance in Arabidopsis, revealing a regulatory interaction between iron and zinc homeostasis.

Arabidopsis Nicotianamine Synthases (NAS) comprise a common core-NAS domain fused to a variable auto-inhibitory C-terminus

This study identifies amino acids critical for AtNAS1 activity, showing that the C-terminal domain auto-inhibits NAS function and that its removal enhances activity.

Energy status-promoted growth and development of Arabidopsis require copper deficiency response transcriptional regulator SPL7

This study shows that SPL7 regulates energy status-promoted growth and development in Arabidopsis by modulating copper deficiency responses and sugar signaling.

Constitutively enhanced genome integrity maintenance and direct stress mitigation characterize transcriptome of extreme stress-adapted Arabidopsis halleri

This study compares transcriptomes of Arabidopsis halleri from highly contaminated and non-metalliferous soils, identifying stress adaptation mechanisms and gene expression changes.

Root-to-shoot iron partitioning in Arabidopsis requires IRON-REGULATED TRANSPORTER1 (IRT1)

This study shows IRT1 in Arabidopsis is involved in root-to-shoot iron transport without requiring its iron transport activity.

Do Arabidopsis Squamosa promoter binding Protein-Like genes act together in plant acclimation to copper or zinc deficiency?

This study investigates whether SPL7, SPL1, and SPL12 in Arabidopsis function together in acclimation to Cu or Zn deficiency, finding SPL7 is involved in Cu deficiency responses but SPL1 and SPL12 are not, and Zn deficiency responses are independent of SPL7.

Convergent evolution in Arabidopsis halleri and Arabidopsis arenosa on calamine metalliferous soils

The paper examines convergent evolution in two Arabidopsis species on metalliferous soils, finding gene and functional network convergence with species-specific molecular factors.

Real-time whole-plant dynamics of heavy metal transport in Arabidopsis halleri and Arabidopsis thaliana by gamma-ray imaging

The paper uses gamma-ray imaging to study real-time zinc transport dynamics in Arabidopsis species, showing differences between hyperaccumulators and non-accumulators.
