2023年6月15日，中国农业大学国家玉米改良中心、玉米生物育种全国重点实验室赖锦盛教授团队以题为“A complete telomere-to-telomere assembly of the maize genome”在国际知名期刊Nature Genetics 上在线发表了玉米全基因组所有染色体端粒到端粒完整无间隙组装结果，在复杂动植物基因组中第一个实现真正意义上的全基因组完...
Presence/absence variation (PAV), a major class of genome structure variation, is pervasive in the maize genome. PAVs present in the B73 but absent from the Mo17 genome have been reported in previous studies. Here, the next-generation sequencing was used to identify the PAVs present in Mo...
(3) there are 267,180 length polymorphism locus in 39,604 genes. (4) Their distributions within the genome in different regions were non-random, and the density followed in a descending order of intron, intergenic, 3’UTR, 5’UTR, promoter, and CDS, with average density of 3.502 Kbp ...
A complete telomere-to-telomere assembly for all chromosomes of maize genome 近期, 我们以Mo17自交系为材料(图1(a)), 完成了玉米基因组 所有染色体的完整无间隙组装,并对其高度重复区域的基因 组结构进行了解析, 相关工作发表于Nature ... J Chen,Z Wang,J Lai - 《Chinese Science Bulletin》 被引量:...
A complete telomere-to-telomere assembly for all chromosomes of maize genome Mo17自交系及 其衍生材料在我国玉米生产中被广泛应用. 之前, 我们通过比 较发现Mo17与B73两个基因组间存在大量的基因顺序及基因 结构变异, 可能与玉米不同自交... J Chen,Z Wang,J Lai - 《Chinese Science Bulletin》 被引量...

The recovered OMA lines represent unique materials for maize genome analysis, genetic, physiological, and morphological studies, and a possible means to transfer maize traits to oat. Descriptions of these materials can be found at http://agronomy.cfans.umn.edu/Maize_Genomics.html ....
This population contains introgressions that cover the majority of the maize genome. The set of NILs displayed an excess of residual heterozygosity relative to the amount expected based on their pedigrees, and this excess residual heterozygosity is enriched in the low-recombination regions near the ...
In addition, these types of populations can be used to address questions regarding genome organization and genetic linkage. The term isogenic line conceptually refers to a pair of inbred lines that differ by a single gene. Near-isogenic lines are not that pure, and contain some proportion of a...
