Detailed Profiling of 17-Hydroxygeranyllinalool Diterpene Glycosides from Species Reveals Complex Reaction Networks of Conjugation Isomers.

Background: Specialised anti-herbivory metabolites are abundant in the solanaceous genus . These metabolites include the large family of 17-hydroxygeranyllinalool diterpene glycosides (HGL-DTGs). Many HGL-DTGs occur exclusively within the genus, but information from the molecular model species , , and the tree tobacco is limited.

Cold Exposure Memory Reduces Pathogen Susceptibility in Based on a Functional Plastid Peroxidase System.

Chloroplasts serve as cold priming hubs modulating the transcriptional response of to a second cold stimulus for several days by postcold accumulation of thylakoid ascorbate peroxidases (tAPX). In an attempt to investigate cross-priming effects of cold on plant pathogen protection, we show here that such a single 24-h cold treatment at 4°C decreased the susceptibility of to virulent pv. DC3000 but did not alter resistance against the avirulent pv.

Plant chromatin, metabolism and development - an intricate crosstalk.

Chromatin structure influences DNA accessibility and underlying gene expression. Disturbances of chromatin structure often result in pleiotropic developmental phenotypes. Interactions between chromatin modifications and development have been the main focus of epigenetic studies.
