A new species, Phyllanthus mutisianus, is described on the basis of a collection from Colombia made by the expedition of Jose Mutis. It is distinguishable from all other neotropical species of Phyllanthus by virtue of the distinctive leaf venation and very long fruiting pedicels. The type specimen lacks mature flowers, but the vegetative morphology, inflorescence, and fruiting structures sugges...

Wood-inhabiting macromycete (WIM) communities in the ecosystem of uneven-aged spruce stands growing on former agricultural land were investigated relation to supply wood substrate, degree rot, and selected climatic ecological conditions. Altogether, 58 WIM species detected at research plots during 2016–2018. The abundance fruiting bodies richness increased from youngest oldest forest stands. hi...

During sexual development, filamentous ascomycetes form complex, three-dimensional fruiting bodies for the generation and dispersal of spores. In previous studies, we identified genes with evolutionary conserved expression patterns during fruiting body formation in several fungal species. Here, we present the functional analysis of two developmentally up-regulated genes, chs7 and sec22, in the ...

Inhibition of DNA replication within the first 6 h of development results in a block in the developmental programme in the social soil bacterium Myxococcus xanthus. We have interpreted these data to imply that M. xanthus requires a new round of DNA replication early in the developmental programme. To further understand the role of DNA replication during development in M. xanthus we focused on t...

armillaria root and crown rot is an important disease of woody plants including fruit, forest and ornamental trees in different regions. the disease is common in isfahan and causes economical losses on a broad range of fruit trees. there only a few tolerant varieties to disease, and there is no efficient method in controlling the disease. therefore, detection of the pathogen from soil is necess...

Myxococcus xanthus is a social bacterium that lives in the soil and undergoes spectacular development to form multicellular fruiting bodies. It contains a large family of eukaryote-like serine/threonine protein kinases. We found that a number of inhibitors for eukaryotic protein serine, threonine, and tyrosine kinases could inhibit the development and sporulation of M. xanthus to various degree...

Stachys L. one of the biggest genus of the Lamiaceae family comprises about 200-300 species.  In this research, aerial parts essential oil composition and content of Stachys lavandulifolia Vahl (Lamiaceae)at different stages (vegetative, full flowering and initial fruiting stages) is reported. The oils obtained by water distillation method (Clevenger apparatus) and analyzed by GC and GC/MS. The...

In the model fungus Podospora anserina, the PaYIP3 gene encoding the orthologue of the Saccharomyces cerevisiae YIP3 Rab-GDI complex dissociation factor expresses two polypeptides, one of which, the long form, is produced through a programmed translation frameshift. Inactivation of PaYIP3 results in slightly delayed growth associated with modification in repartition of fruiting body on the thal...
