造礁珊瑚物种正在经历前所未有的减少，原因是海洋热浪的频率和强度越来越高，以及相关的漂白引起的死亡。从theAcropora hyacinthus物种复合体密切相关的物种在耐热性和耐热共生体的协会不同。我们使用了在2015年美属萨摩亚漂白事件中监测的114个菌落的低覆盖率全基因组测序，以确定在这些物种特征中出现分歧的四个神秘物种（称为HA，HC，HD和HE）之间的遗传差异。隐藏物种在基因组中数千个单核苷酸多态性上存在很大差异，这些多态性在耐漂白物种HE中富集了氨基酸变化。此外，HE还显示了两个特别不同的区域，具有强烈的分化信号。一个约220 kb的基因座，HES1，包含了大多数的固定差异在HE。第二个位点，HES2，固定在HE，但在其他神秘的物种多态性。令人惊讶的是，在HES2处具有HE样单倍型的非HE个体更有可能漂白。在这两个位点，他表现出特定的序列相似性的同源物，鹿角珊瑚millepora。总体而言，在第三次全球漂白事件的漂白弹性强结构的主机神秘的物种，这些物种之间的共生体协会的差异所鼓舞。
Reef-building coral species are experiencing an unprecedented decline owing to increasing frequency and intensity of marine heatwaves and associated bleaching-induced mortality. Closely related species from theAcropora hyacinthusspecies complex differ in heat tolerance and in their association with heat-tolerant symbionts. We used low-coverage full genome sequencing of 114 colonies monitored across the 2015 bleaching event in American Samoa to determine the genetic differences among four cryptic species (termed HA, HC, HD and HE) that have diverged in these species traits. Cryptic species differed strongly at thousands of single nucleotide polymorphisms across the genome which are enriched for amino acid changes in the bleaching-resistant species HE. In addition, HE also showed two particularly divergent regions with strong signals of differentiation. One approximately 220 kb locus, HES1, contained the majority of fixed differences in HE. A second locus, HES2, was fixed in HE but polymorphic in the other cryptic species. Surprisingly, non-HE individuals with HE-like haplotypes at HES2 were more likely to bleach. At both loci, HE showed particular sequence similarity to a congener,Acropora millepora. Overall, resilience to bleaching during the third global bleaching event was strongly structured by host cryptic species, buoyed by differences in symbiont associations between these species.
