new heterothallic species of the genus Sordaria, Sordaria heterothallis ' Ze?ds and Maniotis (FIELDS and MANIOTIS, 1963) and Sordaria thermophila Fields (FIELDS 1968), are the subjects of this study. FIELDS (1963), in a comparative study of the two isolates concluded that they were distinct species on the basis of morphological and cultural studies, and from the results of hybridization experim...

glomerella cingulata is the causal agent of anthracnose disease on citrus that attacks weakened trees. the sexual stage is rare in nature but can be produced in laboratory under certain conditions. sixty-seven single-spore isolates were selected from citrus in mazandaran province to be used in this study. isolates were cultured on ypss for investigating heterothallism and homothallism. to under...

fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

to study the population structure of gibberella fujikuroi species complex, the causal agent of rice foot rot, samples were taken from different rice growing regions of guilan province in 2004. among fourty-one isolates recovered from different cultivars; three isolates did not produce microconidial chain. in order to study the sexual fertility and determine the mating type as well as mating pop...

Septoria musiva Peck is capable of establishing itself on unwounded first-ye ar stems of eastern cottonwood. Natural infections have been observed since 1969 in three forest nurse ries in Mississippi, and inoculations have confirmed that both conidia and ascospores are capable of causing stem infections . This paper offers evide n ce that the fungus Septoria musiva Peck is capable of causing ca...
