🌿 Dicots take a CYP from the herbicide detoxification cup - Danica Goggin 🧬

Fig. 1.Summary of the approach taken to identify tembotrione-metabolizing enzymes in resistant Amaranthus palmeri. A parental resistant population with enhanced tembotrione hydroxylating activity was crossed with a susceptible population to produce pseudo-F2 lines segregating for tembotrione resistance. Candidate resistance genes were identified by RNA-seq and validated by measuring hydroxy-tembotrione production in yeast overexpressing each gene. Polymorphisms in the promoter of the validated gene, CYP72A1182, plus a QTL analysis pinpointing genomic regions associated with resistance, suggest that differential transcriptional regulation of CYP72A1182 is responsible for the differences in hydroxylating capacity between susceptible and resistant plants.

Today the Caspian Sea has dropped to a historic low level due to global warming & it's likely to get much worse. On current emission trajectories, the decline could 10m or more by 2100, with catastrophic consequences for people & nature 🧪🌍🌐🦑🐋🦭.

🧬 Flipped DNA is rewriting evolution
In Lake Malawi, 800+ fish species evolved in record time

– flipped chunks of DNA lock in survival traits and pass them on intact

— humans have them too.
So how your DNA is arranged might matter more than what’s in it

On #BiodiversityDay, we’re celebrating life on an ocean world. Our survival and ability to thrive are inextricably linked with the health of the planet and all of its inhabitants. Over 90% of the habitable space on Earth is in the Ocean, which is home to much of the planet’s biodiversity.

Today I attended a brilliant lecture by Dr. Francesca Morgante on Genetics of Dystonias, at St. George’s.

• Phenotyping matters. Without accurate phenotyping, gene panel testing can yield low diagnostic rates.
• Mitochondrial dysfunction is increasingly recognized

Do you know why we are seeing rising cases of #measles?
Because back before political interference decimated Public Health, we used to close schools when there was a case of #measles. The new pandemic normal is to leave schools open and for reporters to ignore this basic principle. #PublicHealth

“Preventable diseases are making a comeback”

Reading my @bmj.com makes me a mix of angry and sad these days, as well as educating me.

This is another “we humans can’t be trusted to do the right thing” post, I’m afraid.

#MedSky
#VaccinationSavesLives
#PublicHealth
Preventable diseases make "dangerous comeback" Diseases that can be prevented through vaccination, such as measles, meningitis (below), and yellow fever, are re-emerging as millions of children miss vaccinations and funding cuts disrupt programmes and disease surveillance, health leaders have warned. A joint statement from the World Health Organization, Unicef, and Gavi said immunisation efforts were also being threatened by widespread misinformation, population growth, and humanitarian crises. They urged world leaders to strengthen vaccination programmes and to give the problem their "urgent and sustained political attention."
