Divergent transcriptional architectures beyond core CAM genes in facultative and constitutive CAM species in Tillandsia

The paper compares transcriptional architectures of CAM in two Tillandsia species, finding divergent gene expression patterns despite shared core CAM genes.

Small RNAs regulation and genomic harmony: insights into allopolyploid evolution in marsh orchids (Dactylorhiza)

The paper compares small RNA landscapes in two allopolyploid marsh orchid species and their diploid parents to understand how polyploidy affects genomic regulation.

Dark matter of an orchid: metagenome of the microbiome associated with the rhizosphere of Dactylorhiza traunsteineri

The paper analyzes the microbiome of the endangered orchid Dactylorhiza traunsteineri, identifying key bacterial phyla and revealing metabolic potential in its rhizosphere.

Ecological divergence is marked by species specific plastic gene expression and distinct rhizosphere among sibling allopolyploid marsh orchids (Dactylorhiza)

This study examines gene expression and root mycobiome diversity in two allopolyploid orchids to understand how plasticity and environmental factors influence their ecological divergence and persistence.

Recent speciation and adaptation to aridity in the ecologically diverse Pilbara region of Australia enabled the native tobaccos (Nicotiana; Solanaceae) to colonize all Australian deserts

The paper uses genomic data to show that Nicotiana section Suaveolentes colonized Australian deserts by adapting to arid conditions in the Pilbara region starting 5 million years ago.

Decoupled genetic and epigenetic variation in the montane endemic Erodium cazorlanum (Geraniaceae) and a widespread congener

The paper investigates genetic and epigenetic variation in two Erodium species, finding no genetic structure but significant epigenetic variation, particularly in DNA methylation patterns.

Spatial and ecological drivers of population structure in Alkanna tinctoria (Boraginaceae), a polyploid medicinal herb

This study investigates genetic structure in polyploid Alkanna tinctoria using RAD-seq, finding regional structure and neutral processes drive genetic variation.
