Sphingolipids in the trans-Golgi network have been implicated in polar trafficking. Here Wattelet-Boyer et al. show that hydroxylated C24- and C26-acyl-chain sphingolipids are enriched in trans-Golgi network subdomains that are critical for polar sor

Multiple mechanisms behind plant bending

Publikováno v: Nature Plants. 9:13-21

To survive, plants constantly adapt their body shape to their environment. This often involves remarkably rapid bending of their organs such as stems, leaves and roots. Since plant cells are enclosed by stiff cell walls, they use various strategies f

A study of flotation-REST (restricted environmental stimulation therapy) as an insomnia treatment

Autor: Annika, Norell-Clarke, Kristoffer, Jonsson, Annecharlotte, Blomquist, Rolf, Ahlzén, Anette, Kjellgren

Objectives: Flotation-REST is a treatment for deep relaxation, where a person is contained in a stimuli-restricted environment and floats in water with high salt content. The aim was to investigate the effects from flotation-REST on people with insom

International audience; Tissue bending is vital to plant development, as exemplified by apical hook formation during seedling emergence by bending of the hypocotyl. How tissue bending is coordinated during development remains poorly understood, espec

External mechanical cues reveal core molecular pathway behind tissue bending in plants

SummaryTissue folding is a central building block of plant and animal morphogenesis. In dicotyledonous plants, hypocotyl folds to form hook after seedling germination that protects their aerial stem cell niche during emergence from soil. Auxin respon
