Research Abstract

Plant pathogens can affect individual growth and community structure in wild plants in many area including polar regions. In his study, several plant pathogens in polar regions were characterized on species identification, growth response to temperature, and pathogenicity to moss. It is also documented that one of the major plant pathogens may be increased by the recent frequent rainfall in polar regions.
