Hydra vulgaris, the fresh-water polyp, [3] is a small freshwater hydroid with length from 10 mm to 30 mm and width about 1 mm. [4] Description.
Hydra (/ ˈ h aɪ d r ə / HY-drə) is a genus of small freshwater hydrozoans of the phylum Cnidaria.They are native to the temperate and tropical regions. [2] [3] The genus was named by Linnaeus in 1758 after the Hydra, which was the many-headed beast of myth defeated by Heracles, as when the animal has a part severed, it will regenerate much like the mythical hydra's heads.

For instance, the model organism Hydra and the jellyfish Craspedacusta sowerbii are both exclusively freshwater hydrozoans. [2] Hydra and Craspedacusta sowerbii are distantly related and are not closely related to Polypodium. Also, the obligate parasite Myxobolus cerebralis lives in freshwater. Thus, it appears that in the evolution of ...
H. vulgaris may refer to: Hippuris vulgaris, the common mare's tail, a common aquatic plant species found in Eurasia; Hydra vulgaris, a small freshwater hydroid species; Hydrocotyle vulgaris, the marsh pennywort, a small creeping perennial herb species native to North Africa, Europe, Florida and west to the Caspian region
Hydra viridissima is a species of cnidarian which is commonly found in still or slow-moving freshwater [2] in the Northern temperate zone. Hydra viridissima is commonly called green hydra due to its coloration, which is due to the symbiotic green algae Chlorella vulgaris which live within its body. [ 3 ]
Gal4 is a modular protein consisting broadly of a DNA-binding domain and an activation domain. The UAS to which GAL4 binds is CGG-N 11-CCG, where N can be any base. [6] Although GAL4 is a yeast protein not normally present in other organisms it has been shown to work as a transcription activator in a variety of organisms such as Drosophila, [7] and human cells, highlighting that the same ...
Curvibacter sp. is a gram-negative curved rod-formed bacterium which is the main colonizer of the epithelial cell surfaces of the early branching metazoan Hydra vulgaris. [ 16 ] [ 17 ] Sequencing the complete genome uncovered a circular chromosome (4.37 Mb), a plasmid (16.5 kb), and two operons coding each for an AHL (N-acyl-homoserine lactone ...
