Soluble sugar levels affect a diverse array of plant developmental processes. For example, exposure to high levels of glucose or sucrose inhibits early seedling development of Arabidopsis thaliana (L.) Heynh. Media-shift experiments indicate that Arabidopsis seedlings lose their sensitivity to the inhibitory effects of high sugar levels on early development within approximately two days after t...
