许多宿主与共生体的关系是通过垂直传播来维持的。虽然母体共生体传播很常见，但双亲传播相对罕见。原生生物依赖性白蚁是真社会性昆虫，在其后肠中具有专性的、分解纤维素的原生生物。原生生物通过有翅生殖动物（有翅动物）垂直传播，它们分散开来，以双亲方式建立新的殖民地。原生生物依赖的白蚁的垂直传播是不完美的，因为原生生物的有翅类群落往往是不完整的。原生生物的双亲传播可能使有翅类没有必要拥有完整的群落，因为殖民地将从创始的国王和王后那里获得共生体，它们一起可能拥有足够的接种物。为了验证这一假说，对土白蚁Coptotermes gestroian和C.使用18 S rRNA扩增子测序来检查福莫沙坦酸盐和菌落。这些乳白蚁种的原生生物群落均由5种副基白蚁组成。而有翅类往往窝藏1-3原生物种，几乎所有的殖民地窝藏4-5种，这意味着双亲传递。每个原生生物物种存在于至少一个创始有翅的概率被用来确定预期的原生生物发生在殖民地。对于大多数原生生物，预期和观察到的发生没有显着差异，这表明每个原生生物物种只需要窝藏一个创始翅被收购的殖民地。我们的研究结果意味着，双亲传输允许建立繁殖传递足够的共生体社区的殖民地，尽管他们的个人社区是不完整的。我们讨论的背景下，其他bipartally传播的共生体中的原生生物依赖的白蚁的双亲传输。
Many host-symbiont relationships are maintained through vertical transmission. While maternal symbiont transmission is common, biparental transmission is relatively rare. Protist-dependent termites are eusocial insects that harbor obligate, cellulolytic protists in their hindguts. Protists are vertically transmitted by winged reproductives (alates), which disperse to biparentally establish new colonies. Vertical transmission in protist-dependent termites is imperfect, as the protist communities of alates are often incomplete. Biparental transmission of protists may make it unnecessary for alates to harbor complete communities, as colonies would acquire symbionts from both founding kings and queens, which together may harbor sufficient inoculums. To investigate this hypothesis, the protist communities ofCoptotermes gestroiandC. formosanusalates and colonies were examined using 18S rRNA amplicon sequencing. The complete protist communities of theseCoptotermesspecies are composed of five parabasalid species each. Whereas alates often harbored 1–3 protist species, nearly all colonies harbored 4–5 species, implying biparental transmission. The probability of each protist species being present in at least one founding alate was used to determine expected protist occurrence in colonies. For most protists, expected and observed occurrence did not significantly differ, suggesting that each protist species only needs to be harbored by one founding alate to be acquired by colonies. Our results imply that biparental transmission allows founding reproductives to transmit adequate symbiont communities to colonies despite their individual communities being incomplete. We discuss biparental transmission in protist-dependent termites in the context of other biparentally transmitted symbioses.
