摘要
充分利用研究的比较多的模式作物所获得的分子遗传学信息,进而作为较复杂生物基因组研究的基础,是现代分子遗传学常用的手段之一。在此,重点介绍了模式作物拟南芥、玉米和水稻在种子发芽方面的分子遗传学研究进展;概述了小麦穗发芽的分子遗传学研究进展;分析了根据小麦与模式生物在基因组上的共线性,利用比较分子遗传学手段,将拟南芥的ABI3和玉米的VP-1基因作为小麦抗穗发芽的候选基因的可行性。
Using the molecular genetics information from model crops as the foundation of the complicated organism genomes is the regular method for modern molecular genetics. We have introduced the developments of the seed sprouting of some model organism, such as arabidopsis, maize and rice. We also summarized the molecular genetic researches of pre-harvest sprouting for wheat. And then we analyzed that it is feasible to use ABI3 gene from arabidopsis and Vp-1 gene from maize as the candidate genes of pre-harvest sprouting in wheat using method of comparative molecular genetics. This analysis was based on the colinearity of the genomes between wheat and some model organisms.
