Abstract
Comparative Analyses between Functional Markers Concerning Yield-related Traits of Rapeseed and Sequences of Rice Genome Database
Highlights
Comparative genomics is the study of the relationship of genome structure and function across different biological species or strains using kinds of classification methods and alignment techniques
The homologous sequences in rice: These 39 different Expressed Sequence Tags (ESTs) or genes linked with the QTLs of agronomic traits in rapeseed were applied to search homogous sequences
The homologous gene of VHSD was found in the region of QTLs for YP, PNN, PH, SBN and SN. These results showed that some QTLs controlling the similar traits were found in the region of the homologous genes in rice and rapeseed and some have pleiotropy effects
Summary
Comparative genomics is the study of the relationship of genome structure and function across different biological species or strains using kinds of classification methods and alignment techniques. The sequence information and genomic resources of the extensively studied model organisms could be used for marker development, map-based gene cloning and candidate gene identification in other plants. In rapeseed (Brassica napus L.), the fine mapping of the blackleg R gene was based on the conserved regions between Arabidopsis and rapeseed (Mayerhofer et al, 2005). Qin et al (2011) saturated the powdery mildew resistance gene, Pm6, in wheat using the collinearity-based markers by extensively exploiting the genomic resources of rice, Brachypodium distachyon and the comprehensive Triticeae ESTs (Expressed Sequence Tags)
