Origin and evolution of the slime molds (Mycetozoa)
The Mycetozoa include the cellular (dictyostelid), acellular (myxogastrid), and protostelid slime molds. However, available molecular data are in disagreement on both the monophyly and phylogenetic position of the group. Ribosomal RNA trees show the myxogastrid and dictyostelid slime molds as unrelated early branching lineages, but actin and beta-tubulin trees place them together as a single co...
متن کاملDictyostelid Cellular Slime Molds from Caves
Dictyostelid cellular slime molds (dictyostelids) are singlecelled, eukaryotic, phagotrophic bacterivores usually present and often abundant in terrestrial ecosystems (Raper, 1984). These organisms represent a normal component of the microflora in soils and apparently play a role in maintaining the natural balance that exists between bacteria and other microorganisms in the soil environment. Fo...
متن کاملSlime molds transfer knowledge through fusion.
Animals acquire an understanding of the world through experience and instruction. If we touch a hot stove, we burn ourselves and learn to keep our fingers away from glowing red coils. Alternatively, we can avoid the drama of direct experience by heeding the warnings of our parents. Both options are effective and help to guide our future behaviors. And until now, both were believed to require a ...
متن کاملDo cellular slime molds form intercellular junctions?
Intercellular contact specializations such as gap junctions have been thought to play a role in growth and differentiation in many systems. This idea is based on the observation that small molecules can pass directly between the cytoplasms of adjacent cells and on the strong circumstantial evidence that gap junctions may provide for this intercellular permeability (1). Gap junctions are found i...
متن کاملDictyostelid Cellular Slime Molds from Hawai'i
Soil and litter samples, collected from Hawai'i on the islands of Hawai'i, O'ahu, and Kaua'i, were examined for occurrence and distribution of dictyostelid cellular slime molds. In total, 194 samples, from 20 different sites and representing several plant communities, were collected during June 1995 and processed in the laboratory soon thereafter. A total of 10 species and one variety was recov...
