New insights into the regulation of greening and carbon-nitrogen balance by sugar metabolism through a plastidic invertase.

Abstract excerpt

Since the photosynthetic apparatus of plants contains a massive amount of nitrogen, the regulation of its development by sugar signals is important to the maintenance of the carbon-nitrogen balance. Recently, we isolated a new Arabidopsis mutant, sicy (sugar-inducible cotyledon yellow)-192, whose cotyledons were prevented from greening by treatment with sucrose. On treatment with sucrose, the expression of...
