Cloning and phylogenetic analyses of serine/threonine kinase class defense-related genes in a wild fruit crop chestnut rose

摘要

BackgroundChestnut rose (Rosa roxburghii Tratt) is a promising wild fruit crop in Southwest China. However, chestnut rose suffers from several important diseases such as powdery mildew and black spot. Cloning and phylogenetic analysis of plant immunity related genes will strengthen the evolutionary knowledge of plant immune system and will facilitate the utilization of candidate genes in disease resistance breeding programs.
