A new, detailed breakdown of the modern rose genome should help growers improve traits such as pest and drought resistance, and boost the vase life of cut stems, researchers said Monday.
In a study published in Nature Genetics, a multinational team said a fastidious examination of rose DNA has allowed them to compile “one of the most comprehensive plant genomes to date.”
A major export product, roses are a favourite for Valentine’s Day, weddings, and anniversaries — considered by some to be a symbol of love.
Rose petals are a key ingredient for the multi-billion dollar perfume industry.
Study co-author Mohammed Bendahmane of France’s CNRS research institute said growers are always on the lookout for “blockbuster” roses that combine captivating colouring and alluring scent with pest resistance and low water consumption.
The newly-published rose genome will “allow them to considerably accelerate the process of improving different rose varieties,” he told AFP.
The new DNA map was based largely on the genome of a rose known as “Old Blush” or Rosa chinensis, introduced to Europe from Asia in the 18th century.
With its 36,377 genes, the Old Blush is considered one of the main ancestors of today’s tens of thousands of rose cultivars from some 200 known, wild species.
“Its contribution to the creation of modern varieties is considered major: it is this rose plant from which we get the trait of repeat flowering,” said Bendahmane.
‘He’s misunderstood’: Nikki Haley tells Fox News how Trump is actually a really good listener
Former Ambassador to the U.N. Nikki Haley defended President Donald Trump during a Monday appearance with Fox News personality Sean Hannity.
Hannity asked the former South Carolina governor if Trump was "misunderstood."
"I do think he’s misunderstood," Haley replied.
"I can tell you, from the first day to the last day that I worked for the president, he always listened, he was always conscious of hearing other voices, allowing people to debate out the issues, and then he made his decision," Haley claimed.
She argued that, "I saw a president that was very thoughtful, looked at all of the issues, made decisions, and it was a pleasure and honor to work with him."

Tucker Carlson: accepting more migrants to America would ‘despoil it’ and ‘make it a place you wouldn’t want to live’
During a segment with Justin Haskins, a "research" fellow at the far-right climate denial think tank, the Heartland Institute, Fox News host Tucker Carlson disparaged the idea of "climate migrants" who might need asylum from conditions caused by climate change — and escalated to an extreme, racist rant against accepting migrants at all.
"I thought, according to Bernie Sanders and Elizabeth Warren and everybody else on the socialist left, that human beings are causing climate change, that human CO2 emissions, that that's what's causing climate change, that it's going to be catastrophic" said Haskins. "Well if that's true, then why are we bringing people from all over the world, where they produce CO2 emissions less per person, in places like Mexico and Guatemala, places like that, why are we bringing them to the United States, where we produce CO2 emissions per person at a much higher rate?"
