Gene expression patterns in Brassica and other allopolyploid plants
摘要
Abstract
Interspecific hybridization and allopolyploidization lead to the origin of many important crops,and the cultivated Brassica allotetraploids have become one of the most widely used models.During last two decades,it has been popular to study how the allopolyploids regulate and coordinate genetic behavior and gene expression of ge-nomes from different progenitors.By using the constantly developing molecular biological technology,dynamic na-ture of polyploid genomes has been revealed in Brassica and other allopolyploids,with the occurrence of genetic and epigenetic alterations at the initial stage and during evolution process.The obvious changes have been found in gene expressions,including non-additive expression,transgressive expression,expression level dominance,homoeolog expression bias,effects of dosage-balance,etc.These remodulations of genome structure,epigenetic and gene ex-pression patterns have contributed to the evolutionary success of novel allopolyploids into new species in nature.关键词
