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

F. Pavan, J. Azevedo Favory, E. Lacoste, C. Beaumont, F. Louis, C. Blassiau, C. Cruaud, K. Labadie, S. Gallina, M. Genete, V. Kumar, U. Kramer, R. Adriano Batista, C. Patiou, L. Debacker, , S. Legrand

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

R. A. Batista, E. Durand, M. Mörchen, J. Azevedo-Favory, S. Simon, M. Dubin, V. Kumar, E. Lacoste, C. Cruaud, C. Blassiau, M. Barois, A.-C. Holl, C. Ponitzki, N. Faure, W. Marande, , V. Castric

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

V. Castric, R. A. Batista, A. Carre, S. Mousavi, c. mazoyer, C. Gode, S. Gallina, C. Ponitzki, A. Theron, a. bellec, w. marande, S. Santoni, r. mariotti, a. rubini, S. Legrand, , P. Saumitou-Laprade

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.

Differential retention of transposable element-derived sequences in outcrossing Arabidopsis genomes

S. Legrand, T. Caron, F. Maumus, S. Schvartzman, L. Quadrana, E. Durand, S. Gallina, M. Pauwels, C. Mazoyer, L. Huyghe, V. Colot, M. Hanikenne, V. Castric

The paper compares TE dynamics in two Arabidopsis species, finding that orthologous TE insertions are closer to genes, less methylated, and less expressed than non-orthologous ones.
