Evolution of disease-resistance gene in coffee trees (Coffea L.)

Abstract

The ability of plant species to survive over evolutionary time depends to some instance on their capability to maintain and generate useful diversity at resistance loci. Therefore, analysis of diversity and evolution of resistance genes (R) in plant species could be of particular interest in the elaboration of strategies for developing durable resistance mediated by major genes. Molecular analysis of R-gene evolution concern so far mainly plants with short life cycle while perennial plants have retained little attention.
