T. Makino et al., ULTRAWEAK LUMINESCENCE GENERATED BY SWEET-POTATO AND FUSARIUM-OXYSPORUM INTERACTIONS ASSOCIATED WITH A DEFENSE RESPONSE, Photochemistry and photobiology, 64(6), 1996, pp. 953-956
Ultraweak luminescence generated by sweet potato and nonpathogenic Fus
arium oxysporum interactions associated with a defense response was de
tected by a photon-counting method using ultrahigh-sensitive photodete
ctors, The time-dependent intensity variation, the spectrum and the tw
o-dimensional imaging of the ultraweak luminescence are indicative of
the defense response of the sweet potato to F. oxysporum. The producti
on of ipomeamarone as a phytoalexin means that F. oxysporum induced th
e defense response in the sweet potato.
