Sequencing watermelon reveals disease-resistance genes bred out generations ago
Researchers at the Boyce Thompson Institute in Ithaca, New York, have analyzed genomes of watermelon and its ancestors, revealing traits that early breeders may have inadvertently removed in their quest to maximize the red, sweet, watery flesh of the fruit. Their report appears in Plant Biotechnology Journal.

Cucurbit Genetics Cooperative #47 | call for papers
Editors of the Cucurbit Genetics Cooperative are now accepting reports for CGC #47. Reports or manuscripts should be submitted by February 15th, 2024. The CGC committee seeks assistant editors for future CGC reports.
Super-pangenome for watermelon and its wild relatives
“The super-pangenome provides a valuable genetic toolkit for breeders and researchers to improve cultivated watermelon,” said Fei. “By understanding the genetic makeup and evolutionary patterns of watermelons, we can develop varieties with enhanced yield, increased disease resistance, and improved adaptability.”
The “super-pangenome” for watermelon and its wild relatives, the researchers hope, will uncover beneficial genes lost during domestication. Traits of interest affect seeds; rind thickness; fruit size, shape, texture, and sweetness; and improving disease resistance, which might lessen reliance on agrochemicals.
