Hello all, I am starting a project and have some questions that I hope someone may answer. 1) What is the gene(s) that signal for the production of a)Fructose, b)Sucrose and c)Dextrose in fruiting plants? 2) Are they the same gene(s) in a variety of fruiting plants or do they differ (probably differ, but just want to confirm. Thanks in advance for your valuable input. JQ.
