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.

A quarter-million-year-old polymorphism drives reproductive mode variation in the pea aphid

The paper identifies an X-linked 840-kb genomic region responsible for reproductive mode variation in pea aphids, showing divergence dating to ~0.25 million years ago.

Comparative phylotranscriptomics reveals a 110 million years-old symbiotic program

This study reconstructs the ancestral transcriptomic program for root-nodule nitrogen-fixing symbiosis by comparing transcriptomic responses across nine host plants, revealing most RNS novelties originated in a 110 million-year-old ancestor.

The wild grape genome sequence provides insights into the transition from dioecy to hermaphroditism during grape domestication

This study sequenced the wild grape genome to understand the genetic transition from dioecy to hermaphroditism during grape domestication.

Genetic basis and timing of a major mating system shift in Capsella

This study identifies a dominant loss-of-function mutation in the male self-incompatibility gene SCR as the cause of a recent shift to self-fertilization in Capsella orientalis.

Patterns of polymorphism at the self-incompatibility locus in 1,083 Arabidopsis thaliana genomes

The paper analyzes polymorphism at the S-locus in 1,083 Arabidopsis thaliana genomes to understand the historical loss of self-incompatibility, finding multiple independent origins and recombination events during post-glacial colonization.
