Post-harvest tran­scrip­tional changes in onion

During the trans­ition from endo– to eco-dormancy and sub­sequent growth, the bulb of onion (Allium cepa) changes from a sink organ to a source, but the mech­an­isms con­trolling these pro­cesses are not fully under­stood. Chope et al. carry out detailed ana­lysis of whole-bulb physiology, bio­chem­istry and tran­scrip­tional changes in response to sprout­ing and provide evid­ence that the monosaccharide-to-disaccharide ratio and zeatin ribos­ide con­cen­tra­tion are import­ant factors in dis­crim­in­at­ing between sprout­ing and pre-sprouting bulbs. The res­ults also sug­gest that com­mer­cial cur­ing tem­per­at­ures could be reduced without det­ri­mental effects.
