Gametogenesis in the Genus Hydra

1 Molecular phylogenetic study in genus Hydra

Hydra myc2, a unique pre-bilaterian member of the myc gene family, is activated in cell proliferation and gametogenesis

The myc protooncogene encodes the Myc transcription factor which is the essential part of the Myc-Max network controlling fundamental cellular processes. Deregulation of myc leads to tumorigenesis and is a hallmark of many human cancers. We have recently identified homologs of myc (myc1, myc2) and max in the early diploblastic cnidarian Hydra and have characterized myc1 in detail. Here we show ...

Growth of endosymbiotic algae in the green hydra, Hydra viridissima

Stable endosymbiosis depends upon balanced growth of the symbionts. In green hydra, coincident patterns of host and algal mitotic index suggest that coordinated reproduction provides for balanced growth. However, when hydra shrink during food shortage, the population of endosymbiotic algae in a green hydra must likewise decline in size. Thus far, no mechanism of reducing the size of the endosym...

The genus Helvella in Iran

This study is a review on the genus Helvella (Pezizales, Helvellaceae) in Iran. Study on samples deposited in Iran fungal herbarium along with the fresh materials collected by the author revealed that seven species of Helvella, H. acetabulum, H. atra, H. crispa, H. elastica, H. ephippium, H. lacunosa and H. leucopus (as H. monachella) have already been reported from Iran. Three other species vi...
