与白骨壤属（Avicennia）的大多数红树林树种一样，白骨壤A.阿尔巴广泛分布于世界各地的热带和亚热带海岸。红树林在生态系统动态中发挥着重要作用，但据报告，随着人类对沿海地区的压力增加，红树林正在退化。高变遗传标记可用于群体遗传学研究，以估计影响水平和群体恢复潜力。微卫星标记A.通过筛选富集微卫星二核苷酸重复的部分基因组文库获得alba。在所设计的20对引物中，有6对引物扩增出了多态性微卫星，其变异程度令人满意。
Like most species of mangrove trees of the genus Avicennia , A. alba is widely distributed among tropical and subtropical coasts around the world. Mangroves play an essential role in ecosystem dynamics but are reported to be regressing as human pressure increases on coastal zones. Hypervariable genetic markers are useful for population genetics studies, to estimate the level of impact and the populations potential for recovery. Microsatellite markers for A. alba were obtained by screening a partial genomic library enriched for microsatellite dinucleotide repeats. Among 20 primer pairs defined, six amplified polymorphic microsatellites with a satisfying level of variability.
