Release of Floral Fragrance Visualized

Have you ever thought of when flowers emit their scents? KAIST mechanical engineers and organic scientists instantly visualized how typically a lily releases a floral scent utilizing a laser interferometry methodology. These measurement outcomes can present new insights for understanding and additional exploring the biosynthesis and emission mechanisms of floral volatiles. Why is it necessary to know this? It is well-known that the perfume of flowers impacts their interactions with pollinators, microorganisms, and florivores. For occasion, many flowering vegetation can tune their scent emission charges when pollinators are lively for pollination. Petunias and the wild tobacco Nicotiana attenuata emit floral scents at night time to draw night-active pollinators. Thus, visualizing scent emissions will help us perceive the ecological evolution of plant-pollinator interactions. Many teams have been attempting to develop strategies for scent evaluation. Mass spectrometry has been one extensively used methodology for investigating the perfume of flowers. Although mass spectrometry reveals the standard and amount of floral scents, it’s unimaginable to instantly measure the releasing frequency. A laser-based fuel detection system and a smartphone-based detection system utilizing chemo-responsive dyes have additionally been used to measure unstable natural compounds (VOCs) in real-time, however it’s nonetheless arduous to measure the time-dependent emission price of floral scents. However, the KAIST analysis staff co-led by Professor Hyoungsoo Kim from the Department of Mechanical Engineering and Professor Sang-Gyu Kim from the Department of Biological Sciences measured a refractive index distinction between the vapor of the VOCs of lilies and the air to measure the emission frequency. The floral scent vapor was detected and the refractive index of air was 1.0 whereas that of the main floral scent of a linalool lily was 1.46. Professor Hyoungsoo Kim stated, “We count on this expertise to be additional relevant to numerous industrial sectors resembling growing it to detect hazardous substances in an area.” The analysis staff additionally plans to establish the DNA mechanism that controls floral scent secretion.Reference: Kim H, Lee G, Song J, Kim SG.
