Journal ArticleDOI
Metabolizable and Non-Metabolizable Sugars Activate Different Signal Transduction Pathways in Tomato
Alok Krishna Sinha,Markus Hofmann,Ulrike Römer,Walter Köckenberger,Lothar Elling,Thomas Roitsch +5 more
TL;DR: The strong activation of MAPKs and the fast and transient induction of Lin6 expresssion by the fungal elicitor resembles the effect of turanose, palatinose, and fluoro-Suc and indicates that non-metabolizable sugars are sensed as stress-related stimuli.
Journal ArticleDOI
A dedicated spectrometer for dissolution DNP NMR spectroscopy
James Leggett,Robert I. Hunter,Josef Granwehr,Rafal Panek,Angel J. Perez-Linde,Anthony J. Horsewill,Jonathan McMaster,Graham Smith,Walter Köckenberger +8 more
TL;DR: The design and construction of a dedicated spectrometer for DNP applications that is based on a magnet with two isocentres is described, which proved to be superior to the strategy involving two separate magnets.
Journal ArticleDOI
The transport of sugars to developing embryos is not via the bulk endosperm in oilseed rape seeds.
Edward R. Morley-Smith,Marilyn J. Pike,Kim Findlay,Walter Köckenberger,Lionel Hill,Alison M. Smith,Stephen Rawsthorne +6 more
TL;DR: In this paper, the fate of sucrose (Suc) supplied via the phloem to developing oilseed rape (Brassica napus) seeds has been investigated by supplying [14C]Suc to pedicels of detached, developing siliques.
