Sucrose Acts as a Signal Transmitter for Light-Dependent Root Architecture Formation in Arabidopsis

Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem.
