Modulation of host plant immunity by Tobamovirus proteins.

abstract：BACKGROUND AND AIMS:Whole-genome duplication (WGD) events are considered important driving forces of diversification. At least 11 out of 52 Brassicaceae tribes had independent mesopolyploid WGDs followed by diploidization processes. However, the association between mesopolyploidy and subsequent diversification is equiv...
