Article Synopsis
- The order Rickettsiales includes a variety of bacteria that interact with hosts in different ways, such as causing diseases or benefiting the host.
- Researchers created a comprehensive dataset to explore how these bacteria became dependent on their hosts and whether that dependence evolved independently across different lineages.
- The study found that various Rickettsiales lineages evolved their host associations through similar but distinct pathways, involving the loss of certain metabolic functions and the development of specific mechanisms for interacting with host cells.
Paramecium (Ciliophora, Oligohymenophorea) is a good model to study ciliate biogeography. Extensive sampling mainly in northern hemisphere has led to 16 valid morphological species description thus far. However, a majority of hard-to-reach regions, including South East Asia, are underinvestigated.

In the present study, these bacteria were investigated using morphological and molecular methods. For "Ca.

The redundancy created by WGDs typically results in a phase of massive gene loss. However, some WGD-derived paralogs are maintained over long evolutionary periods, and the relative contributions of different selective pressures to their maintenance are still debated.
