Many fungi have hyphal fusion ability, includ-ing rice blast fungus [Magnaporthe grisea (Hebert) Barr nov. Comb. (Anamorph Pyricularia oryzae Cavara)], and which is one of the major causes to pathogenic variation. Santo H has observed the phenomenon of hy -phal fusion in rice plant under electron micro-scope and isolated some races which were dif-ferent from parental ones.
