Abstract

The association between locoweeds (poisonous Astragalus and Oxytropis species) and seed borne fungal endophytes (Undifilum spp.), present in both North America and China, has drawn attention due to their toxicity to livestock. The absence of host specialization and non-mutualistic relationship with the hosts of locoweed endophytes implicated that their evolution history should be different from other endophyte-host associations. Accordingly, the study conducted co-evolutionary analyses based on the non-coding chloroplast KGCB region of 14 examples of locoweeds and the ITS region of the endophytes isolated from them. The results showed that American locoweed endophytes had co-evolution tendency with their hosts, while the Chinese endophytes switched among different hosts, and failed to show a clear co-evolutionary pattern. Horizontal transmission behavior could be applied to explain the absence of co-evolution for Chinese locoweed endophytes, which suggests that Chinese locoweed endophytes might have a different association mechanism from the American locoweed endophytes.
