Rhizoferrin is a novel carboxylate-type siderophore which has recently been isolated from
Rhizopus microsporus and other fungi of the Mucorales (Zygomycetes). The present …

Polyamines are important regulators of growth and differentiation in a variety of cells,
including parasitic protozoa. Promastigotes of Leishmania species have high levels of …

We analyzed the regulation of sterigmatocystin biosynthesis in wild type and mutant strains
