Modern roses, famous for their colors and ability to bloom again and again, owe much of their genetics to Chinese old garden roses. Until recently, it was unclear which wild species contributed to modern roses and where did the key gene for repeat flowering come from. Now, a new study published in Annals of Botany identified the wild ancestors of Chinese old garden roses and traced the origins of the key gene responsible for continuous flowering…
