The morphology of different genera of duckweed differs greatly, ranging from the relatively complex structure of members of the genus Spirodela to the extremely reduced structures found in the genus Wolffia.
Thus the averages of different genera of a taxon may differ completely in predicted solubility.
A number of different genera have been described from Fayum, including Catopithecus, Proteopithecus, Apidium, Qatrania, Propliopithecus, Oligopithecus, Parapithecus, and Aegyptopithecus.
Starting from the maximum number of different genera in the middle part of the Middle Permian Epoch, extinction within these invertebrate faunas significantly reduced the number of different genera by 12 to 70 percent by the beginning of the Capitanian Age (the latest age of the Middle Permian Epoch).
Using the maximum number of different genera in the middle part of the Guadalupian Epoch (about 272.3 million to 259.8 million years ago) as a benchmark, extinction within marine invertebrate faunas significantly reduced the number of different genera by 12 to 70 percent by the beginning of the Capitanian Age some 266 million years ago.
The ability to recognize likeness in things of different genera is said to be the key.
Species of fungi of different genera such as Cladosporium herbarum, Aspergillus niger, Stachybotrys sp. and Alternaria have been found on these supports.
There were no significant differences in parasitism and predation rates between native or exotic plots or between plants of different genera.
Microalgae of different genera and species have been found to exhibit significant antioxidant activity in vitro (Geetha et al. 2010; Rao et al. 2006) and, thus, they are considered as potential natural sources of antioxidants in vivo.
We transferred the cloned SPI-1 type III system into bacterial strains of different genera and found that there is a SPI-1 gene expression defect in these strains.
Macrofossils and megafossils of different genera, which were found in twelve localities in the mountains of northwest Iberia, provide spatially precise evidence of their distribution in the region during the Holocene.
