The ®ssion yeasts are members of the fungal order Schizosaccharomycetales, a candidate deepdiverging group within Ascomycota. Although a great deal of molecular information is available from Schizosaccharomyces pombe, a model eukaryote, very little is available from other members of this group. In order to better characterize mitochondrial genome evolution in this fungal lineage, the mitochondr...

The 0.F factor is a regulatory protein that is responsible for directing gene expression in the forespore compartment of developing cells of the spore-forming soil bacterium BacMlus subtilis. The cJF factor is encoded by the promoter-distal member of sporulation operon spollA, which consists of cistrons called spoIIAA, spollAB, and spollAC. Genetic evidence indicates that the activity of oF is ...

Adiantum meishanianum is an endemic species distributed only in Meishan village, Kaohsiung, Taiwan. Because its sporangia contain only abortive spores, A. meishanianum has been regarded as having a hybrid origin, presumably with A. caudatum, A. malesianum, and A. philippense as the putative parents. The aim of this study is to confirm the hybrid origin and determine the parental lineages of A. ...

The effect of calcium on saprophytic growth and pathogenicity of Phytophthora cinnamomi Rands was studied as well as the influence of calcium on the resistance of avocado to root rot caused by the pathogen. Saprophytic growth of the pathogen was increased significantly by calcium, although the pathogenicity of the fungus was not influenced significantly. Ungrafted Edranol, Duke 7 and Martin Gra...
