Description
An Yang and co-authors map a gene family in apple trees in a 2026 study. The family, called HD-Zip IV, helps build outer cell layers, waxy coatings, and fat stores in plants. It had never been fully cataloged in apple, a major fruit crop.
The team found seventeen family genes spread unevenly over eight chromosomes. All carry the same core parts seen in relatives from other plants, and family trees place them in five groups shared with two model species. Duplicated pairs show signs of purifying selection, which keeps their roles stable. Gene activity varied by tissue, in leaf, fruit skin, and bark. One gene, switched on hard under dry-like stress, made lab-grown apple tissue tougher when boosted.
