TL;DR: It is shown that transposable elements—particularly siRNA-targeted TEs—are associated with reduced gene expression within both species and also with gene expression differences between orthologs, and that A. lyrata TEs are targeted by a lower fraction of uniquely matching siRNAs, which are associated with more effective silencing of TE expression.

TL;DR: This work presents the response of over 150 wild accessions to three different environmental variables, and suggests that many of the flowering-time pathways identified by mutagenesis, such as those that respond to day length, contribute to flowering- time variation in the wild.

TL;DR: A systematic protein-protein interaction network of virulence effectors from the ascomycete pathogen Golovinomyces orontii and Arabidopsis thaliana host proteins is generated and suggests the existence of a molecular host-pathogen interface that is conserved acrossArabidopsis accessions, while evolutionary adaptation occurs in the immediate network neighborhood of effector targets.

TL;DR: LFY signaled equally well from all layers and had substantial long-range action within layers and AP1 had only limited nonautonomous effects, apparently mediated by downstream genes because activation of early target genes by AP1 was cell-autonomous.

TL;DR: Earlier studies of GA signaling in the Gramineae are extended to include a dicot species, Arabidopsis, and indicate that GAMYB-like genes may mediateGA signaling in growth and flowering responses.
