New study has now given a glimpse into the genetics of modern roses, revealing how human intervention shape their development over time. Roses have cherish for centuries as ornamental plants, but much of their genetic background has remain unclear.
Researchers now know how roses from Eastern and Western species combined.
This research has given valuable insights into breeding hardier and more visually striking varieties.
As it highlights the importance of genetic diversity.
This could play a key role in making roses more adaptable to future climate changes.
For many years, roses were grow separately in China and Europe.
When Chinese roses made their way to Europe in the 18th century, it change the course of rose cultivation.
As the ‘Old Blush’ rose from China has often credit with this transformation, scientists are now pointing to Rosa odorata as another significant contributor.
The fusion of Eastern and Western species laid the foundation for modern roses, known for their repeat blooming and varied forms, as we see in gardens today.
Led by Professor Zhangjun Fei at the Boyce Thompson Institute, the research team began by studying the genome of a popular modern rose variety called ‘Samantha®’.
It has four sets of chromosomes, which made the genetic mapping process quite complex.
Due to this information, scientists can now advance the understanding of rose genetics and breeding.
Researchers team also sequence the DNA of 233 other rose varieties, building a comprehensive map that traces the evolution of modern roses.
This work is set to help breeders develop roses that bloom longer, are easier to care for, and resist pests and diseases better.
It also underscores the need to maintain genetic diversity to ensure roses can continue to adapt to the changing environment.
