Sources of black Sigatoka resistance in wild banana diploids [PDF]

Revista Brasileira de Fruticultura, 2020
Black Sigatoka (black leaf streak disease) is caused by the fungus Mycosphaerella fijiensisMorelet. This phytopathogen colonizes banana leaves, resulting in reduced photosynthesis and decreased productivity.

Cercospora beticola: The intoxicating lifestyle of the leaf spot pathogen of sugar beet

Molecular Plant Pathology, Volume 21, Issue 8, Page 1020-1041, August 2020., 2020
The hemibiotrophic fungus Cercospora beticola applies various virulence strategies to infect sugar beet and is currently only managed in‐field through integrated practices. Abstract Cercospora leaf spot, caused by the fungal pathogen Cercospora beticola, is the most destructive foliar disease of sugar beet worldwide. This review discusses C.

The AVR4 effector is involved in cercosporin biosynthesis and likely affects the virulence of Cercospora cf. flagellaris on soybean

Molecular Plant Pathology, Volume 21, Issue 1, Page 53-65, January 2020., 2020
Summary One of the most devastating fungal diseases of soybean in the southern USA is Cercospora leaf blight (CLB), which is caused mainly by Cercospora cf. flagellaris. Recent studies found that the fungal effector AVR4, originally identified in Cladosporium fulvum as a chitin‐binding protein, is highly conserved among other Cercospora species.
