The mechanisms suppressing nitrate assimilation in plants under nitrogen-repleted condition are poorly known, but researchers may have made a breakthrough. They have recently studied the transcription of nitrate assimilating genes in a unicellular red alga and found that deletion of the negative domain of transcription factor CmMYB1 or a previously unknown protein CmNDB1 is responsible…

The latest gene editing technology, prime editing, expands the ‘genetic toolbox’ for more precisely creating disease models and correcting genetic problems, scientists say. In only the second published study of prime editing’s use in a mouse model, Medical College of Georgia scientists report prime editing and traditional CRISPR both successfully shut down a gene involved…

Researchers have found a very high prevalence of Bartonella bacteria in tumors and tissues — but not blood samples — taken from dogs with hemangiosarcoma, a cancer of the blood vessels. Hemangiosarcoma (HSA) is an aggressive, deadly cancer that arises from cells lining the blood vessels. It is responsible for two-thirds of all heart or…
