Description
Genes that pace the cell cycle multiplied as flowering plants doubled their genomes, and the copies did not all stay equal. Aldrin Cantila and co-authors charted that history in this 2026 study. Cyclin genes govern growth and reproduction across the cabbage family. Ten genomes were compared: four from Arabidopsis relatives and six from Brassica crops.
The sweep found 1,087 cyclin genes in twenty-three types. Nearly two thousand duplication events touched most of them. Whole-genome doubling was the main engine of expansion, above all in the doubled Brassica genomes. Some copies tied to flowering time differences. Knowing which copies matter could help breeders tune when crops bloom.
