Identification of pathways required for to colonize alfalfa using TraDIS-.

Unlabelled: Enteropathogenic bacteria, such as , have been linked to numerous fresh produce outbreaks, posing a significant public health threat. The ability of to persist on fresh produce for extended periods is partly attributed to its capacity to form biofilms, which pose a challenge to food decontamination and can increase pathogenic bacterial load in the food chain. Preventing colonization of food products and food processing environments is crucial for reducing the incidence of foodborne outbreaks.

Fine tuning of hormonal signaling is linked to dormancy status in sweet cherry flower buds.

In temperate trees, optimal timing and quality of flowering directly depend on adequate winter dormancy progression, regulated by a combination of chilling and warm temperatures. Physiological, genetic and functional genomic studies have shown that hormones play a key role in bud dormancy establishment, maintenance and release. We combined physiological and transcriptional analyses, quantification of abscisic acid (ABA) and gibberellins (GAs), and modeling to further investigate how these signaling pathways are associated with dormancy progression in the flower buds of two sweet cherry cultivars.

From bud formation to flowering: transcriptomic state defines the cherry developmental phases of sweet cherry bud dormancy.

Background: Bud dormancy is a crucial stage in perennial trees and allows survival over winter to ensure optimal flowering and fruit production. Recent work highlighted physiological and molecular events occurring during bud dormancy in trees. However, they usually examined bud development or bud dormancy in isolation.
