# Innovative Genetic Markers University of California Scientists Present RUBY, a Vivid Red Pigment By Kalin Ned | Published 2025-05-26 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/genetic-marker References: [zhaolab.biosci.ucsd.edu](https://zhaolab.biosci.ucsd.edu/ruby/)  A team of scientists at the [University of California](https://www.trendhunter.com/trends/color-olo), [Riverside](https://www.trendhunter.com/trends/holiday-maruchan-ramen-cottage-party) has engineered an innovative genetic marker called RUBY. It produces a vivid red pigment identical to the betalain compounds found naturally in beets. This breakthrough development offers a safer, more visually apparent alternative to conventional antibiotic or herbicide resistance markers currently used in genetic modification research. Unlike traditional markers that can damage test cells, RUBY functions as a non-destructive visual indicator. When successfully incorporated into plant DNA, the genetic marker causes transformed cells to turn a distinctive red color detectable without specialized laboratory equipment. The researchers demonstrated RUBY's practical application by creating genetically modified mustard plants that change color when exposed to the pesticide azinphos-ethyl. The food industry might utilize RUBY-modified plants as [natural biosensors for detecting pesticide residues](https://www.trendhunter.com/trends/biotechnology-platform) or other chemical contaminants in food production systems.
