During an oomycete survey in December 2015, 10 previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds channels saltmarshes, lagoon ecosystems river estuaries at seven sites along the Algarve coast South Portugal. Phylogenetic analyses LSU ITS datasets, comprising all described species, new relevant distinctive sequences available GenBank, provided u...

Homothallic switching of the mating-type MATa gene in Saccharomyces cerevisiae results from replacement by gene conversion of MAT-Ya DNA with Y(alpha) sequences copied from one of two unexpressed donors. MATa preferentially recombines with HML(alpha), located near the left end of chromosome III, but can use HMR(alpha), near the right chromosome end. MATa donor preference depends on a 700 bp ori...

The Saccharomyces cerevisiae spore wall is a multilaminar coat that surrounds individual spores and protects them from environmental insult. Scanning electron microscopy reveals that the four spores of an ascus are connected by interspore bridges. Transmission electron microscopy of spores indicates that these bridges are continuous with the outer layers of the spore wall. In chs3 mutants, whic...

Neurospora pannonica is homothallic, with 8-spored asci. Immature asci are usually swollen and noncylindrical while the mature asci are narrow and cylindrical. The two meiotic divisions resemble those of other Neurospora species. However, the orientation of third-division mitotic spindles and the distribution of nuclei in the swollen asci are irregular. Ascospores are arranged irregularly at fi...

During extensive surveys of global Phytophthora diversity 14 new species detected in natural ecosystems Chile, Indonesia, USA (Louisiana), Sweden, Ukraine and Vietnam were assigned to major Clade 10 based on a multigene phylogeny nine nuclear three mitochondrial gene regions. now comprises subclades. Subclades 10a 10b contain with nonpapillate sporangia, range breeding systems mainly soil-and w...
