Fungal pathogen,Fusarium solani, was also
reported as a model pathogen ofL. japonicus
(Takeuchi et al. 2007 ). A fungal isolate,
MAFF240020 (deposited in GenBank, National
Institute of Agrobiological Sciences), causes the
wilt disease by root rot inL. japonicusaccession
Gifu B-129. In addition, MAFF240020 also
causes chlorotic to necrotic lesions on leaves
after wound inoculation. Thus, F. solani
MAFF240020 is suitable for studying pathogenic
interactions inL. japonicus.
15.6 Conclusion
As discussed above, our knowledge about the
Lotusdefense mechanism largely relies on the
study of symbiosis and mainly restricted to MTI.
Even so, these studies revealed the presence of
close relationship between defense and symbiosis
and thus highlight strongly the importance of the
study ofLotus–pathogen interactions. Investiga-
tions of the defense mechanisms inL. japonicus,
especially about ETI, will contribute to the
understanding of not only legume defense
mechanisms but also the true nature of symbiosis.
