TL;DR: The phytohormone cytokinin was originally discovered as a regulator of cell division and later was described to be involved in regulating numerous processes in plant growth and development including meristem activity, tissue patterning, and organ size.

TL;DR: The results demonstrate the critical function of the PDX1 protein family for metabolism, whole-plant development, and vitamin B6 biosynthesis in higher plants and Interestingly, the mutant form ofPDX1 has severely reduced capability to oligomerize, potentially suggesting that oligomerization is important for function.

TL;DR: The method presented here affords a simple and rapid, yet robust complement to previously validated methods of polar metabolite profiling by gas-chromatography mass-spectrometry.

TL;DR: Interestingly, in all scenarios the primed state was lost as soon as the freezing tolerance had reached the level of naïve plants indicating that an effective memory was associated with an altered physiological state.

TL;DR: In planta complex assembly of PDX proteins, based on split-YFP and FPLC assays, and can demonstrate their presence in higher complexes of around 750 kDa, these findings provide first insights into in planta vitamin B₆ synthase complex assembly and new information on how the differentPDX proteins affect plant metabolism.
