![]() PhlF protein bound its operator sequence (phlO) in the absence of 2,4-diacetylphloroglucinol (DAPG) but dissociated from phlO in the presence of DAPG. Further study shows that phlF gene codes for a repressor protein which can interact with an inverted repeated sequence, phlO, located upstream of the gene related to biosynthesis of DAPG. Recently, it is demonstrated that 2,4-DAPG can serve as signal molecule to construct a transcriptional switch that is similar to Tet on/off system.Īccording to a research conducted to study the biosynthesis pathway of DAPG, researchers found that there is a negative correlation between phlF gene expression level and the DAPG synthetic amount. Introduction-A New Type of Transcriptional SwitchĢ,4-DAPG (DAPG), full name 2,4-diacetylphloroglucinol, is a natural phenol found in specific strains of Gram-negative bacterium Pseudomonas fluorescens. Luckily, after further literature reading and brainstorming, we find this system will bring us more surprise. atroviride will respond to the invasion of pathogens. atroviride through the DAPG-Off/On system, and T. ![]() When our device detected that the plant is infected with pathogens and is in poor condition by analyzing the changes in volatile organic compounds (VOC) released by plants, it will tell our engineered T. We choose the DAPG-Off/On System to serve as the link between our device and engineered organisms for it is supersensitive. Hence it requires us to make our device and our engineered organisms connected. ![]() There may be additional customs charges on your order once it reaches the destination country.This year, we aim to construct a diseases-monitoring system for automatic agriculture in which hardware and organisms can act as a whole.
