Long days induce adaptive secondary dormancy in seed of the Mediterranean plant Aethionema arabicum

This study shows that long-day light regimes induce secondary dormancy in Aethionema arabicum seeds, delaying germination to avoid risky summer conditions.

The dimorphic diaspore model Aethionema arabicum (Brassicaceae): Distinct molecular and morphological control of responses to parental and germination temperatures

The paper investigates how parental and germination temperatures affect molecular and morphological responses in dimorphic diaspores of Aethionema arabicum, identifying gene expression and hormonal differences that regulate dormancy and germination.

Heat stress response and transposon control in plant shoot stem cells

This study examines how heat stress affects plant shoot stem cells, showing they suppress heat response pathways and maintain development, while mutants with defective TE defense show impaired recovery and persistent TE activation.

A versatile CRISPR-based system for lineage tracing in living plants

The paper introduces a CRISPR-based lineage tracing system in plants that uses Cas9 to correct a frameshift mutation, enabling fluorescent labeling of cell lineages without altering plant phenotypes.

Phytochromes mediate germination inhibition under red, far-red, and white light in Aethionema arabicum

The study identifies a phytochrome chromophore biosynthesis mutant in Aethionema arabicum, showing phytochromes mediate light inhibition of seed germination and influence plant morphology.

Two AGO proteins with transposon-derived sRNA cargo mark the germline in Arabidopsis

The paper identifies AGO5 and AGO9 as markers of an early-segregating germline in Arabidopsis, loaded with transposon-derived small RNAs in the shoot apical meristem.

A novel model plant to study the light control of seed germination

The paper identifies Aethionema arabicum as a model plant for studying light-inhibited seed germination, revealing antipodal transcriptional regulation of hormone balance compared to Arabidopsis.
