POWRE: Genetic Linkage Map & Quantitative Trait Loci Analysis for Clarkia lingulata and C. bilboba ssp. australis

Clarkia lingulata（默塞德Clarkia）是一个最近从C.二叶种australis（马里波萨克拉基亚属），并且经常被引用为植物中快速物种形成的“经典”例子。 然而，除了原始的染色体描述和种群水平分析（为这些物种之间的关系提供了间接证据）之外，这些物种没有进一步的遗传特征。 本文的工作将建立与舌形克拉克藻的物种形成相关的遗传事件和性状的染色体定位。二叶种澳大利亚。 利用分子生物学方法，在原始物种描述的时候，将提供分析的基础，特别是确定与生殖隔离的C。lingulata和C.二叶种澳大利亚。 从这项研究中获得的信息对于理解染色体变化在适应和物种形成中的重要性非常重要。这项研究建立在首席研究员现有知识的基础上，并扩大了她在生态遗传学方面的广度。 来自这个POWRE奖的资金将使PI能够在本土和非本土入侵物种之间的物种形成和杂交研究中寻求新的问题。

Schierenbeck 9973734Clarkia lingulata (Merced Clarkia) is an example of recent speciation from C. biloba ssp. australis (Mariposa Clarkia) and is often cited as a "classic" example of rapid speciation in plants. However, beyond the original chromosomal description and a population level analysis that provides indirect evidence for the relationship between these species, there has been no further genetic characterization of these species. The work proposed here will establish the specific chromosomal location of the genetic event and traits associated with the speciation of Clarkia lingulata from C. biloba ssp. australis. The use of molecular methods unavailable at the time of the original species description will provide the basis for analyses specifically to identify those traits associated with the reproductive isolation of C. lingulata and C. biloba ssp. australis. The information resulting from this research is important in understanding the importance of chromosomal change in adaptation and speciation.The research builds on the existing knowledge of the principal investigator and expands her breadth in ecological genetics. Funding from this POWRE award will enable the PI to pursue new questions in the study of speciation and hybridization between native and non-native invasive species.
