F. Nakashima The Lewis histo-blood group system is characterized by the expression of the Lea and Leb antigens in the gastrointestinal tract, whose synthesis results in interactions between α2-L-fucosyltransferase (FUTII) and α3/4-L-fucosyltransferase (FUTIII) enzymes coded by the FUT2 (19q.13.3) and FUT3 (19p13.3) genes. FUTII and FUTIII fucosylate the type 1 oligosaccharide precursor (Galβ1→3NAcGlcβ1→3-R) at distinct […]

PenaE-mail: spena@dcc.ufmg.br ABSTRACT Of all DNA markers on the human Y-chromosome, the tetra-local Y-linked microsatellite DYS464 is the most polymorphic. We genotyped DYS464 in 677 male samples collected worldwide, maintained in […]
Gene expression and nutrient utilization in the basideomycete Moniliophthora perniciosa suggest the existence of regulatory mechanisms of catabolite repression
I.S. Ganda Moniliophthora perniciosa, a hemibiotrophic fungus (characterized by biotrophic and saprotrophic phases in its life cycle), is the causal agent of witches’ broom disease (WBD), which negatively affects the Latin American cocoa (Theobroma cacao) production. The southern region of Bahia, in Brazil, had the first occurrence of WBD in 1989, which led to a […]
