Altemaria solani

A number of investigators have found that reagents that react with sulfhydryl groups can reproduce the symptoms of ozone damage. Dass and Weaver reported this effect in white bean. Tomlinson and Rich reported the same effect in tobacco, and Rich and Tomlinson found that conidiophores of Altemaria solani became more susceptible to ozone if they were pretreated with iodoacetamide. It appears that effects on sulfhydryl content may be quite early events in the toxic reactions initiated by ozone. One should remember, however, that symptoms of ozone and PAN injury are quite different, and one cannot explain the effects of both pollutants as sulfhydryl oxidizers. 

Antimycin A is effective against Altemaria solani spores(42)5 karumin is effective against Rhizoctonia solani ( iD. Nikkomycin is being used to cure trees of Dutch elm disease in Hamden, Connecticut(44). It inhibits the formation of chitin and stops the myceTia of Ceratocy-stis ulmi from growing normally.

Another fungal pathogen Altemaria produces a variety of nonhost-selective phytotoxins291 such as aromatic polyketides (alternariol, zinniol) and reduced polyketides (alternaric acid, solanapyrones). Alternaric acid292 isolated from Altemaria solani shows unique physiological effects on the hypersensitive cell death of potato... 

Consequently, if the postulates of Grasso et al. should be further substantiated, there is the chance that the important group of rust fungi and some other pathogens such as Altemaria solani will not be affected by G143A resistance (Table 11).
