“…Sugars modulate nearly all fundamental processes throughout the entire life cycle of plants, including embryogenesis, germination, growth, development, reproduction, senescence, and responses to diseases and environmental stimuli (Smeekens, 2000;. In general, sugars upregulate genes involved in biosynthesis, transport, and storage of reserves and cell growth and downregulate those associated with photosynthesis, reserve mobilization, and response to stresses (Graham, 1996;Koch, 1996;Ho et al, 2001). Studies with Arabidopsis thaliana and rice (Oryza sativa) have revealed intimate interaction between sugar and plant hormones, environmental stimuli, and metabolic signaling pathways (Sheen et al, 1999;Gibson, 2000;Smeekens, 2000;Coruzzi and Zhou, 2001;Gazzarrini and McCourt, 2001;Rolland et al, 2002Rolland et al, , 2006Hong et al, 2003;Chen et al, 2006).…”
