Optimization Process of Plant Growth Environment for Improving Content Compounds Using Physiological and Genetic Information in a Closed-type Plant Factory

A closed-type plant factory (plant factory) can control growth environments in confined spaces with artificial lights and hydroponic systems. The environment of a be modulated without having to consider the natural climate, so that high value plants rich useful compounds or low toxic uniformly consistently produced. However, process optimizing condition settings increase decrease target tends complicated, given various parameters factory. An efficient optimization for producing was shown using physiological genetic information case Stevia rebaudiana (stevia). This study conducted determine optimal conditions stevia sweet steviol glycosides (SGs) compounds. All environmental were selected based on previous studies relating biosynthesis such SGs as stevioside (Stev) rebaudioside-A (Reb-A). yield evaluation Stev Reb-A transcription levels SGs-related genes. SGs-rich provides an example increased decreased system.
