The sucrose-trehalose 6-phosphate nexus is conserved in flowering plants with different phloem loading and carbon storage strategies.

ABSTRACT: Trehalose 6-phosphate (Tre6P) is a signalling metabolite that maintains sucrose homeostasis and links plant growth and development to the availability of sucrose. Most of our knowledge of the nexus between Tre6P and sucrose comes from studies on arabidopsis (Arabidopsis thaliana), and it is unclear whether this close relationship is generally conserved across other species. To address this question, we investigated the diel changes in sucrose and Tre6P in leaves from a phylogenetically diverse set of angiosperms with different phloem loading and carbohydrate storage strategies: arabidopsis, Alchemilla molis, strawberry (Fragaria×ananassa), Plantago major, melon (Cucumis melo), and wheat (Triticum aestivum). Despite large differences in their sucrose and Tre6P levels, there were positive co
