Israel: Researchers develop a transgenic potato that emits fluorescent light in response to stress

Tridge summary

Researchers from the Hebrew University of Jerusalem have developed a new method for early detection of abiotic stress in potato crops by creating a fluorescent potato variety. This method, which involves expressing a redox-sensitive fluorescent protein in response to reactive chemical molecules produced by the tubers under stress, can alert growers to potential problems and allow them to take corrective action in time. The research, published in Plant Physiology, also showed that the accumulation of reactive oxygen species occurs in the early stages of a plant's response to stress, and suggested that whole-plant redox imaging could be a valuable tool for understanding plant stress responses and enhancing phenotyping in plant breeding programs.

A group of scientists from the Hebrew University of Jerusalem has found a new method for the early detection of abiotic stress in plants in potato crops, by developing a variety that emits fluorescent light in the early stages of stress. This method can help alert growers of this issue and provide them with enough time to address problems before they lose the crop to this issue. The research, published in Plant Physiology, details that the scientists chose to implement in the potato (Solanum tuberosum) a gene with a redox-sensitive fluorescent protein - targeting chloroplast 2 (roGFP2) - which is expressed in the presence of reactive chemical molecules of oxygen produced by tubers when they experience stress. Thus, fluorescence becomes an indicator of abiotic stress, since the more stress a plant experiences, the more fluorescent protein it will produce and the more intense its brightness will be. The potato's fluorescence cannot be observed with the naked eye, but it is ...
