Yellow-fleshed watermelon varieties result from a natural genetic variation affecting lycopene production, the pigment responsible for the typical red color. Instead of lycopene, these varieties accumulate other carotenoids, resulting in hues ranging from pale yellow to vibrant gold. Exploring the genetic basis of this phenomenon provides valuable insights into carotenoid biosynthesis and its regulation in plants.
Understanding the mechanisms behind yellow watermelon coloration offers potential benefits for nutritional enhancement and diversification of fruit crops. Historically, yellow watermelons predate many common red varieties and represent an important part of agricultural biodiversity. Investigating their unique properties can lead to the development of new cultivars with improved nutritional profiles and adaptability to different growing conditions. This research also contributes to a broader understanding of plant pigment genetics and evolution.
