Differential gene expression in filamentous cells of Ustilago maydis.

When fungi interact with plants as pathogens or as symbionts, there are often changes in fungal cell morphology and nuclear state. This study establishes the use of cDNA microarrays to detect gene expression changes in Ustilago maydis cells that differ in structure and nuclear content. Categorizing differentially expressed genes on the basis of function indicated that U.

Gene expression during Ustilago maydis diploid filamentous growth: EST library creation and analyses.

Ustilago maydis is an important model system for the plant pathogenic smut and rust fungi. Critical to the continued development of this model is establishing genomic resources. We have constructed a cDNA library from a forced diploid culture of U.

Thidiazuron-induced plant regeneration from hypocotyl cultures of St. John's wort (Hypericum perforatum. cv 'Anthos').

 St. John's wort (Hypericum perforatum. cv 'Anthos') is a medicinal plant with evidence of efficacy as an anti-depressant.
