WebApr 13, 2024 · The RNA polymerase II degradation factor Degradation Factor 1 (Def1) is important for DNA damage repair and plays various roles in eukaryotes; however, the biological role in plant pathogenic fungi is still unknown. In this study, we investigated the role of Def1 during the development and infection of the rice blast fungus Magnaporthe … WebDonor cells typically act as donors because they have a chunk of DNA called the fertility factor (or F factor). This chunk of DNA codes for the proteins that make up the sex pilus. …
The episome that harbors the F factor can exist as an independent plasmid or integrate into the bacterial cell's genome. There are several names for the possible states: • Hfr bacteria possess the entire F episome integrated into the bacterial genome. • F bacteria possess F factor as a plasmid independent of the bacterial genome. The F plasmid contains only F factor DNA and no DNA from the bacterial genome. WebOne cell, the donor cell (F +), gives up DNA; and another cell, the recipient cell (F −), receives the DNA. The transfer is nonreciprocal, and a special pilus called the sex …
