Transposable elements create distinct genomic niches for effector evolution among Magnaporthe oryzae lineages.

ABSTRACT:

Background

Plant-pathogen interactions are characterized by evolutionary arms races. At the molecular level, fungal effectors can target important plant functions, while plants evolve to improve effector recognition. Rapid evolution in genes encoding effectors can be facilitated by transposable elements (TEs). In Magnaporthe oryzae, the causal agent of blast disease in several cereals and grasses, TEs play important roles in chromosomal evolution as well as the gain or loss of effector genes in host specialized lineages. However, a global understanding of TE dynamics driving effector evolution at population scale and across lineages is lacking.

Results

Here, we focus on 16 AVR effector loci assessed across a global sampling of 11 reference genomes and 447 newly generated dra
