thirty five monoconidial isolates of the fungal culture collection pyricularia grisea were examined, to identify the vegetative compatibility groups and characterize the genetic diversity of isolates as through rep-pcr genomic fingerprinting. the isolates were collected from ricefields during 1997-1999. genetic diversity of p. grisea isolates was studied as based on dna fingerprinting through r...

The present article introduces a model based on cognitive consistency principles to predict how new identities become integrated into the self-concept, with consequences for intergroup attitudes. The model specifies four concepts (self-concept, stereotypes, identification, and group compatibility) as associative connections. The model builds on two cognitive principles, balance–congruity and im...

J. H. JONES AND C. RUSSELL (Department of Oral Medicine, University of Manchester) Superficial candidal penetration occurs in some cases of human oral leukoplakia which may progress to carcinoma. The relationship of mycelial penetration to leukoplakic change is not clearly understood and this experiment was designed to test the hypothesis of a direct association. One of two groups each of 60 ra...
