Does inbreeding depression affect the extinction risk of wild populations of Primula sieboldii?

为了揭示近交衰退的遗传结构，对濒危植物报春花进行了近交衰退的QTL分析。携带GA0343基因座附近共同祖先的等位基因的后代出现白化的概率较高，叶片较小，现蕾较晚，开花较少。这一结果表明，在基因座ga0343附近存在一个有害的隐性等位基因

To reveal the genetic architecture of inbreeding depression, the QTL analysis of inbreeding depression was conducted in a threatened plant, Primula sieboldii. The progeny which have the allele derived from a common ancestry around the locus ga0343, showed high probability of being albino, small leaf, late budding and small number of flowers. This result suggested that there is a deleterious recessive allele around the locus ga0343
