The epiphytic lichen Lobaria pindarensis is a Himalayan endemic species with little information on distribution, genetic diversity and structural complexity. During an intensive survey in the Nepal Himalayas, we collected 1256 thallus fragments from 45 phorophyte species to study their distribution and population genetics along an elevational gradient. We quantified genetic diversity and population structure of each symbiont at 17 fungus specific and 9 alga specific microsatellite loci. The Bayesian clustering identified three and two distinct gene pools for mycobiont and photobiont. We found that genetic diversity, allelic richness and gene pool composition and distribution were significantly influenced by elevation. We discovered both clonally and sexually reproduced repeated genotypes of the symbionts.

喜马拉雅山附生叶地衣小叶扁豆的遗传多样性和结构取决于海拔

附生的地衣小bLobaria pindarensis是喜马拉雅特有种,几乎没有关于分布,遗传多样性和结构复杂性的信息。在尼泊尔喜马拉雅山进行的一次深入调查中,我们从45个自发植物中收集了1256个th虫片段,以研究它们沿海拔梯度的分布和种群遗传学。我们在17个真菌特异性和9个藻类特异性微卫星基因座处量化了每个共生体的遗传多样性和种群结构。贝叶斯聚类确定了三个和两个不同的基因库为真菌和光生物。我们发现遗传多样性,等位基因丰富度以及基因库组成和分布受海拔高度影响。我们发现了共生体的克隆和性繁殖的重复基因型。
