Chinese Scientists Unravel the Genome Sequence of Chayote to Improve Its Tuber and Fruit Development

February 10, 2021

Chinese scientists from the Beijing Academy of Agriculture and Forestry Sciences have unraveled the genomic sequence of chayote which will serve as the key for future development and genetic improvement of the fruit.

The scientists used Nanopore third-generation sequencing combined with Hi-C data to create a draft of the chayote genome. The genome size of chayote is large for the Cucurbitaceae family and was found to have the closest genome sequence to snake gourd vegetable. The scientists also found out the genes responsible for the fruit texture, pigment, flavor, flavonoids, antioxidants, and plant hormones for chayote fruit development.

There is no complete genome of chayote available at present. The findings provide a better understanding of the evolution of the Cucurbitaceae family and provide insights for genetic modification and breeding.
