TL;DR: The physiological effects of transgenic potato plants on RNA interference (RNAi)-inactivated StSUT4 expression is examined and external supply of gibberellic acid leads to even more pronounced differences between wild-type and StS UT4-RNAi plants regarding tuber yield and internode elongation, indicating a reciprocal regulation of StSut4 and gibBerellins.

TL;DR: A review of low-Reynolds-number transport processes in plants can be found in this article, where the current understanding of the mechanism and quantitative description of these flows are discussed, connecting theory and experiments as far as possible.

TL;DR: In poplar, expression of PtaSUT4 was found to consistently respond to environmental stimuli, suggesting a significant role in the regulation of sugar export from leaves in this passive symplasmic phloem loader.

TL;DR: Biochemical methods confirmed the capacity of SUT1 to form a dimer in plants and yeast cells in a redox-dependent manner and under native-like conditions, a phloem-specific reduction of the dimeric form of the St S UT1 protein was detectable in SUT2 antisense plants, whereas constitutively inhibited antisense Plants showed reduction only of the monomeric form.

TL;DR: All vascular plants seem to have evolved efficient osmotic pumping units, despite their huge disparity in size and morphology, which extends the physical understanding of phloem transport.
