Two nearly complete genomes reveal the molecular mechanism underlying the significant fruit quality differences caused by bud sport between yellow and white‐fleshed loquat (Eriobotrya japonica L.)

The Plant Journal, Volume 128, Issue 3, November 2026.
SUMMARY Bud sport is a common and stable somatic variation in perennial fruit trees. Loquat (Eriobotrya japonica L.) is an evergreen fruit tree that can be categorized into yellow‐fleshed and white‐fleshed types based on the flesh color. To uncover the genetic basis, we herein assembled two nearly complete genomes for a yellow‐fleshed ‘Dongting’ loquat
