Chromatin Looping Drives Nectar-Producing Flower Organs

Researchers at Japan’s Nara Institute of Science and Technology found that CRABS CLAW and MYB proteins help form a DNA loop that promotes the development of nectar-producing flower organs. Using single-nucleus RNA sequencing and spatial transcriptomics in Arabidopsis, the team also identified genes linked to sugar transport and scent-compound production. The findings were published in Nature Communications on October 17, 2026.
