2010 SFT heterosis for yield in tomato NG.pdf
个人认为,这是关于杂种优势研究最重要的进展,这篇文章宣告对杂种优势的研究由假设水平,进入到了分子水平.
同时这个研究也为这个观点"It has been suggested that heterosis might result from the tuned activities of dosage-dependent regulatory systems controlling signaling cascades and transcriptional networks." 提供了支持证据."Our results provide a notable example of single-gene overdominance for tomato yield and offer empirical evidence that, rather than being caused by allelic interactions,subtle changes in gene dosage can lead to overdominance."简单说:杂合位点导致基因剂量的改变,产生了杂种优势.AA(两拷贝),Aa(1拷贝),aa(0拷贝).
