We have isolated about five hundred temperature-sensitive mutants specific for the mitochondrial functions. Their growth on glycerol is defective at 36 degrees C and/or 20 degrees C. While most of the mutations were nuclearly inherited, about thirty were found to be of mitochondrial origin. 1) Four mitochondrial mutations (three cryosensitive, one thermosensitive) were localized close to chloramphenicol and erythromycin resistance loci of the mitochondrial DNA, that is in the region coding for the 23 S ribosomal RNA. One of the mutation interfered with the expression of the chloramphenicol resistance gene. 2) A dozen nuclear mutations were isolated from a strain which is labelled with mitochondrial drug resistance markers (chloramphenicol, erythromycin, and paromomycin). Among the temperature sensitive respiratory deficient mutants, we have selected the mutations that supress the resistant phenotypes. We describe two non allelic such mutations, one being cryosensitive, the other thermosensitive. Both supress the expression of the mitochondrial chloramphenicol resistance gene. The temperature sensitive growth on glycerol and the modified antibiotic phenotype segregated together as a single recessive mutation. A biochemical study...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
