This paper gave a brief introduction on the concept of redundancy, its hypothesis and redundancy degree, and briefly reviewed the research advances in redundancy theory and in the methodologies about species redundancy, layer redundancy, gene redundancy, and growth redundancy. 本文扼要介绍了冗余的概念、冗余假说和冗余度的含义,对近年来国内外物种冗余、层次冗余、基因冗余和生长冗余等有关冗余理论和方法的研究进展作了简要回顾和分析。
Ecological redundancy theory studies mainly on redundant species, the relationship between redundant species and the function of ecosystem, growth redundancy and gene redundancy. 生态冗余理论研究主要集中于冗余物种,冗余物种和生态系统功能之间的关系及植物的器官(生长)冗余和基因冗余。
Some Sox gene exhibit a remarkable crosstalk and functional redundancy among each other. 部分Sox基因之间在功能上相互交叉并且是可以相互替代的。
However, wheat is hexaploid that consists of three homologous chromosomes and with a large number of repetitive sequences and gene redundancy, natural mutation rate is very low, genetic base is narrow and resistant starch content is very low. 但普通小麦是六倍体,具有三个同源的染色体组,有大量的重复序列和基因冗余,自然突变率很低,遗传基础较狭窄,抗性淀粉含量很低。
Determination of gene function is particularly problematic when studying large gene families because redundancy limits the ability to experimentally assess the contributions of individual genes. 当研究大的基因家族时基因功能的确定非常困难,这是因为基因家族中基因功能的冗余限制了通过实验来验证单个基因功能的能力。
