Ua ʻike ka poʻe noiʻi i kahi archaeon hou i ka pilina symbiotic i loko o kahi ʻōnaehana microbial moana e hōʻike ana i ka hōʻemi nui ʻana o ka genome i ka loaʻa ʻana o kahi genome i kāʻili ʻia he 238 kbp wale nō a loaʻa iā ia kahi hana koʻikoʻi e pili ana i ka hoʻoili ʻike genetic. Hoʻopili mua kāna genome i ka mīkini no ka hoʻopili hou ʻana o DNA, ka unuhi ʻana, a me ka unuhi. Loaʻa ʻole ia i nā ala metabolic āpau no laila e hōʻike i ka hilinaʻi metabolic āpau i ka host. Ua kapa ʻia ʻo Candidatus Sukunaarchaeum mirabile, ʻo ia ke ʻano he mea kelepona e mālama wale ana i kāna kumu hoʻohālikelike a ua ulu aʻe e hoʻokokoke i ke ʻano o ke ola. Me ka Sukunaarchaeum mirabile e ʻike ʻia ma ke ʻano he loulou ma waena o nā mea kelepona a me nā maʻi virus, ua koi kēia ʻike i kekahi e noʻonoʻo e pili ana i nā koi liʻiliʻi o ke ola kelepona.
ʻO nā Dinoflagellates he pūʻulu o nā algae eukaryotic single-celled e lawe ana i ʻelua flagella like ʻole. ʻO lākou ka hapa nui o ka plankton moana a ʻike ʻia e mālama i nā kaiāulu microbial symbiotic.
Ma kahi noiʻi hou, hoʻonui ʻia ka genome hoʻokahi-cell o ka bacteria pili me ka dinoflagellate Citharistes regius hōʻike ʻia ka loaʻa ʻana o kahi kaʻina pōʻai like ʻole o 238 kbp me kahi haʻahaʻa haʻahaʻa GC (guanine-cytosine) o 28.9%. Ua ʻike ʻia ua hōʻike ke kaʻina i ka genome piha o kahi prokaryote. Ua hōʻike hou ʻia ka nānā ʻana he archaeon ka mea e lawe ana i kēia genome. Aia a hiki i kēia manawa, ʻo ka genome archaeal piha loa i ʻike ʻia ʻo ia ka genome 490 kbp o Nanoarchaeum equitans. ʻO ka genome archaeon i ʻike ʻia ma kēia haʻawina ʻaʻole ia ma mua o ka hapalua o kēia nui, akā ʻike ʻia ua piha loa. Ua hōʻoia ʻia ka hoʻokolokolo hou ʻana he hōʻike maoli ia i kahi genome archaeon piha a ua kapa ʻia ʻo ia Candidatus Sukunaarchaeum mirabile.
ʻO ka archaeon hou i ʻike ʻia ʻO Ca. Sukunaarchaeum mirabile hōʻike i ka hōʻemi nui loa o ka genome i ka loaʻa ʻana o kahi genome i kāʻili ʻia he 238 kbp wale nō (no ka hoʻohālikelike ʻana, ʻo ka nui genome o archaea maʻamau ma kahi o 0.5 a 5.8 Mbp aʻo ka nui genome o nā maʻi ma waena o 2 kb a ʻoi aku ka 1 Mbp). Eia kekahi, ua ʻike ʻia ka loaʻa ʻana o ka hana koʻikoʻi i ka hoʻoili ʻana i ka ʻike genetic. Hoʻopili mua ia i ka mīkini no ka hoʻopili hou ʻana o DNA, ka unuhi ʻana, a me ka unuhi. Loaʻa ʻole ia i nā ala metabolic āpau no laila e hōʻike i ka hilinaʻi metabolic āpau i ka host.
ʻO Ca. Sukunaarchaeum mirabile Ua like ia me nā maʻi maʻi i ka loaʻa ʻana o kahi genome liʻiliʻi i hoʻolaʻa ʻia no ka hoʻomau ʻana i ka genetic self-perpetuation a me ka hilinaʻi piha ʻana o ka host e koi ʻia e ka hoʻemi metabolic. Eia naʻe, ʻaʻole like me nā maʻi virus, Sukunaarchaeum mirabile Loaʻa iā ia kāna mau mea pono unuhi a me nā ribosomes. ʻAʻole nele ia i nā genes mīkini hana hou a ʻaʻole hilinaʻi i ka mea hoʻokipa no kēia. ʻO kēia ka ʻokoʻa nui ma waena o nā mea kelepona a me nā virus. Sukunaarchaeum mirabile ʻO ke kumu, he mea cellular e mālama wale ana i kāna kumu hoʻohālikelike i ulu a hoʻokokoke i ke ʻano viral o ke ola.
me Sukunaarchaeum mirabile ʻike ʻia ma ke ʻano he loulou ma waena o nā mea kelepona a me nā maʻi virus, ua koi kēia ʻike i kekahi e noʻonoʻo e pili ana i nā koi liʻiliʻi o ke ola kelepona.
