Description
Xiurong Xu and Shiming Cheng catalogue the HDZ gene family in Chinese chestnut and test how its members react to stress. These transcription factor genes help plants weather hard conditions. A genome scan found twenty-five of them, spread over twelve chromosomes and split into four subfamilies, the largest holding thirteen.
All carry the family's conserved homeodomain, and most are predicted to work in the nucleus, with one targeted to the chloroplast. Their control regions hold hormone and stress response elements. Expression shifted by tissue and stress type, and one gene, CmHDZ15, swung strongly under shade and heat or cold. The set gives breeders targets for hardier chestnuts.
