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.
Journal ArticleDOI

TL;DR: A generalized linear model was developed to estimate classical water status indicators from the expression levels of the three selected genes under controlled conditions, independent of the four tested genotypes and the stage (pre- or post-flowering) of the plant.

TL;DR: In this article, the authors used the sunflower (Helianthus annuus L.) as a model species to study the transcriptomic response to water deficit both in greenhouse and field conditions.
Journal ArticleDOI
Different genetic architectures underlie crop responses to the same pathogen: the {Helianthus annuus * Phoma macdonaldii} interaction case for black stem disease and premature ripening.

TL;DR: This work provides the first insights on the genetic architecture of sunflower PR resistance in the field and identifies a succession of genetic components involved in the sunflower resistance to PR and BS diseases caused by Phoma macdonaldii along the development of the {plant * pathogen}.
