The newly released study of longan germplasm resources in 2022 showed that longan fruit performance traits are influenced not only by genetic factors but also by environmental factors; the results of principal component analysis and cluster analysis were basically consistent. Moreover, the National Fruit Tree Germplasm Longan Nursery in Fuzhou is the largest resource nursery of high-quality longan in China, with 343 germplasm resources collected from China, Indonesia, Thailand, and the United States.

  Longan, which has both medicinal and nutritional values, contains much higher GABA (γ-aminobutyric acid) content than tomato. Using longan healing tissues as raw material, constructing vectors and gene editing for key genes of its GABA synthesis pathway will greatly increase the GABA content in longan and construct a longan cell line for long-term succession and expand the culture to Establish a high GABA producing longan cell factory to produce high GABA longan healing tissues continuously, and cooperate with downstream companies to extract GABA, which will make a great contribution to the pharmaceutical industry.
