TL;DR: It is found that the genomic architecture of flowering time has been shaped by the most recent whole-genome duplication, which suggests that ancient paralogues can remain in the same regulatory networks for dozens of millions of years.

TL;DR: Evidence is provided for a role of PAs, particularly Spd, in increasing fruit shelf life, probably by reducing post-harvest senescence and decay.

TL;DR: It is shown that in double-flowered sunflower mutants, such as those captured by Vincent van Gogh in his famous nineteenth-century sunflower paintings, an insertion into the promoter region of a CYCLOIDEA (CYC)-like gene (HaCYC2c) that is normally expressed specifically in WT rays is instead expressed throughout the inflorescence, presumably resulting in the observed loss of actinomorphy.

TL;DR: The detailed genotypic and phenotypic analysis of a sunflower (Helianthus annuus L.) association mapping population that captures nearly 90% of the allelic diversity present within the cultivated sunflower germplasm collection is described.

TL;DR: Transgenic tomato lines overexpressing yeast spermidine synthase (ySpdSyn), an enzyme involved in polyamine (PA) biosynthesis, were developed to suggest that PA-mediated susceptibility to B. cinerea is linked to interference with the functions of ethylene in plant defense.
