The nuclear body appears surrounded by a membrane that is a single layer in some places (arrowheads) and a double membrane in others (arrows). Top panel scale bar = 1Β΅m, bottom panel scale bar = 500nm. 651:-dependent, likely receptor-mediated import of extracellular proteins has been observed under laboratory conditions, although it is of unknown functional significance. This may suggest that Planctomycetota and eukaryote endocytosis mechanism share a common evolutionary origin, that the two processes may be an example of 481:
It has been reported that the budding process involves transfer of naked DNA to the daughter cell, after which it is then surrounded by a nucleoid membrane. However, three-dimensional reconstructions indicate that DNA is never surrounded by a closed membrane in a newly created bud, but instead is
