Evidence of heterokaryosis in streptomyces coelicolor A3(2)

Hyphae from mixed cultures of complementary auxotrophs of Streptomyces coelicolor A3(2) did not grow on minimal media (MM) when fertility plasmids ( SCP1 and SCP2) were missing in both strains. The addition of one part per cent of complete medium (CM) to MM allowed growth of vigorous colonies among the tiny colonies of the parental types. The former, amounting to 1%-10% of the total population, turned out to be heterokaryons. They could be propagated on the same medium by plating of hyphal fragments. When five parts per cent of CM were added to MM, beside the heterokaryotic colonies, vigorous 'spindles' of aerial mycelium were formed whenever complementary colonies overlapped. When the SCP1 and SCP2 plasmids were present in one or both parents a clear constraint on the outburst of heterokaryotic aerial mycelium was observed.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
