Digital gene expression QTL analysisas an efficient gene mapping tool

我们的目标是开发一种新的基于全基因组基因表达分析数据的QTL(QTL)定位方法。在本研究中，发展了定量数字基因表达分析方法，可以分析分离的个体等多个样本中数千个基因的表达。此外，还建立了一种探索DNA多态的新工具，该工具能够同时对多个基因座进行基因分型。这些技术为数字表达QTL分析奠定了基础。

We aimed at developing a novel QTL (quantitative trait locus) mapping procedure based on genome-wide gene expression analysisdata in rice. In the present study, quantitative digital gene expression analysis method was developed, allowed to analyzing expression of thousands of gene in multiple samples, like segregated individuals. Additionally, a novel tool for exploring DNA polymorphisms was also established and it enabled to genotyping many loci at a time. These techniques were basis of digital expression QTL analysis.
