ALL OF THE SAME FOLKS WHO OPPOSED DDT WILL OPPOSE THIS:

Scientists have modified a plant's genetic sequence to make it produce high levels of a key malaria drug, potentially helping meet the large global demand.

The team identified genes involved in making artemisinin, altering their activity to produce three times more of the drug than "normal" plants make.

The plant-based production of the drug sometimes fails to meet demand.

The shrubs don't produce enough of the chemical in their leaves.

The work appears in the journal Molecular Plant.

"Nearly half of the world's population is at risk of malaria," said co-author Kexuan Tang of Shanghai Jiao Tong University.

"Our strategy for the large-scale production of artemisinin will meet the increasing demand for this medicinal compound and help address this global health problem."

The team produced a high quality draft of the Artemisia annua plant's genome and used this information, along with data on how genes are expressed, to engineer plants that produced high levels of artemisinin.

The World Health Organization (WHO) says malaria affected about 216 million people in 91 countries in 2016, and caused an estimated 445,000 deaths worldwide that year alone.

"Artemisia annua remains the sole source of the World Health Organization recommended treatment for malaria, which continues to be a devastating disease in the developing world," said Prof Ian Graham from the University of York, who was not involved with the study.
