Recent advances in sequencing technology promoted the blowout discovery of super tiny microbes in the
Diapherotrites
,
Parvarchaeota
,
Aenigmarchaeota
,
Nanoarchaeota
, and
Nanohaloarchaeota
(DPANN) superphylum. However, the unculturable properties of the majority of microbes impeded our investigation of their behavior and symbiotic lifestyle in the corresponding community.
