As coral reefs decline, restoring lost coral populations has been hampered due to the paucity of genetic information available for many coral species. In the Caribbean, the symmetrical brain coral Pseudodiploria strigosa, a prominent framework builder of the reef, has experienced an accelerated decline due to stony coral tissue loss disease (SCTLD). Colonies of P. strigosa gene-banked in response to the threat of SCTLD in Florida, USA, were sampled to develop 148 novel single nucleotide polymorphism (SNP) markers using genotyping-by-sequencing (GBS). The observed heterozygosity (Ho) and expected heterozygosity (He) ranged from 0.008 to 0.888 and 0.018 to 0.500, respectively. Deviations from Hardy–Weinberg equilibrium within populations, measured by the inbreeding coefficient index (Fis), ranged from − 0.799 to 0.923. In total, 96 SNPs were found to deviate significantly from Hardy–Weinberg (p < 0.05). These SNPs can be used for genetic population analysis to assist management and restoration of P. strigosa.

随着珊瑚礁的减少，由于缺乏许多珊瑚物种的可用遗传信息，恢复失去的珊瑚种群受到阻碍。在加勒比地区，由于石珊瑚组织损失病 (SCTLD)，对称脑珊瑚Pseudodiploria strigosa是珊瑚礁的主要框架建造者，其数量正在加速下降。P. strigosa的殖民地为了应对美国佛罗里达州 SCTLD 的威胁，我们对基因库进行了采样，以使用基因分型测序 (GBS) 开发 148 个新的单核苷酸多态性 (SNP) 标记。观察到的杂合性 (Ho) 和预期杂合性 (He) 的范围分别为 0.008 至 0.888 和 0.018 至 0.500。通过近亲繁殖系数指数 (Fis) 衡量的种群内哈迪-温伯格平衡的偏差范围为 - 0.799 至 0.923。总共发现 96 个 SNP 显着偏离 Hardy-Weinberg (p < 0.05)。这些 SNP 可用于遗传种群​​分析，以协助管理和恢复P. strigosa。
