Plant biotrophic fungal pathogen usually loss its original host after gainning new one. what kind of molecular marker can be us for check it?
The best example is from oomycete evolution:
Orthologous protease inhibitor effectors from the Irish potato famine pathogen, Phytophthora infestans, and its sister species, Phytophthora mirabilis, which is responsible for infection of Mirabilis jalapa, are adapted to protease targets unique to their respective host plants. Amino acid polymorphisms in both the inhibitors and their target proteases underpin this biochemical specialization. The recent results link effector specialization to diversification and speciation of this plant pathogen. (Science 31 January 2014: Vol. 343 no. 6170 pp. 552-555 DOI: 10.1126/science.1246300)
Thank you very much for your interesting and informative response. This mean different targets leading to variation of genes, finally specialization.
Fungi are well known for such types of unfaithful behaviour. Well the primary reason is the host defense mechanisms which forces them to jump host. Ultimately, they will attack host where they have to spend minimum amount of energy to overpower the defense mechanisms of the host.
The very interesting thing many fungi give up their original host after infecting new host, mechanisms underlying which is less understand.
