The evolutionary history and functional specialization of microRNA genes in Arabidopsis halleri and A. lyrata

This study investigates the evolutionary history and functional specialization of miRNA genes in Arabidopsis halleri and A. lyrata, showing rapid birth-and-death dynamics and integration into core biological processes.

Dominance modifiers at the Arabidopsis self-incompatibility locus retain proto-miRNA features and act through non-canonical pathways

The paper investigates sRNA precursors at the Arabidopsis self-incompatibility locus, showing they repress recessive alleles through non-canonical pathways and generate diverse sRNA molecules.

The diallelic self-incompatibility system in Oleaceae is controlled by a hemizygous genomic region expressing a gibberellin pathway gene

The paper identifies a hemizygous genomic region containing a gibberellin pathway gene that controls self-incompatibility in Oleaceae plants, linking GA catabolism to SI responses.

The genetic architecture of the load linked to dominant and recessive self-incompatibility alleles in Arabidopsis halleri and A. lyrata

This study compares the accumulation of linked deleterious mutations between dominant and recessive S-alleles in Arabidopsis species under balancing selection.

Widespread coexistence of self-compatible and self-incompatible phenotypes in a diallelic self-incompatibility system in Ligustrum vulgare (Oleaceae)

The paper investigates self-incompatibility in Ligustrum vulgare, finding self-compatible individuals and showing that low selfing rates are compatible with theory only if inbreeding depression is high.
