The genetic architecture of quantitative variation in the self-incompatibility response within Phlox drummondii (Polemoniaceae)

Flowering plants display extensive variation in selfing rate, a trait with significant ecological and evolutionary consequences. Many species use genetic mechanisms to recognize and reject self-pollen (termed self-incompatibility or SI), and the loss of SI is one of the most common evolutionary transitions among flowering plants. Despite the ubiquity of transitions to self-compatibility (SC), little is known about the genetic architecture through which SC evolves. Specifically, it is important to determine if SC has a polygenic or simple genetic basis and if variation in compatibility localizes to the genomic locus causing self-pollen recognition (the “S-locus”). Phlox drummondii (Polemoniaceae) has been a model system for exploring mating system evolution and expresses extensive range-wide variation in the SI response. Here we investigate the genetic architecture of SC variants segregating within this otherwise SI species. Using multiple independent crosses, we uncover numerous QTLs as..., , # The genetic architecture of quantitative variation in the self-incompatibility response within Phlox drummondii (Polemoniaceae)

显花植物的自交率存在广泛变异，该性状具有重要的生态与进化效应。许多物种通过遗传机制识别并排斥自身花粉，该机制称为自交不亲和（self-incompatibility, SI）；而自交不亲和的丢失是显花植物中最常见的进化转变之一。尽管向自交亲和（self-compatibility, SC）的演化转变普遍存在，但学界对自交亲和演化背后的遗传结构仍知之甚少。具体而言，明确自交亲和是否具有多基因或单基因简单遗传基础，以及亲和性变异是否定位于调控自身花粉识别的基因组位点（即“S位点”），是至关重要的科学问题。德克萨斯福禄考（Phlox drummondii，花荵科Polemoniaceae）是探究交配系统演化的模式系统，其自交不亲和响应在全分布区内存在广泛变异。本研究针对该原本为自交不亲和的物种内分离的自交亲和变异的遗传结构展开探究。通过多组独立杂交实验，本研究发现了多个数量性状基因座（quantitative trait locus, QTL）……
