... to eliminate DNA that was previously amplified during the life cycle. Here we test this hypothesis by comparing the relative copy number of ribosomal DNA and two protein-coding genes with quantitative PCR before and after zerfall in the cultured foraminifer Allogromia laticollaris strain CSH. Our results...

... transformation of distinctive fusiform zygotes into equally distinctive radiate “embryos,” indicate further differences between this foraminiferoidal sarcodinian and such a simple isomorphic foraminifer as Allogromia laticollaris . Culture observations on species of Cibicides , Planorbulina , and agglutinating...

.... sp., genetically matches sequences of undescribed and uncharacterized allogromiids deposited in GenBank from Cyprus and Jamaica. Allogromia arnoldi is genetically and morphologically distinct from A. laticollaris Arnold, A. laticollaris strain CSH, A. sp. NF (Lee & Pierce, 1963), environmental...

... satellite formation are the direct result of motile interactions, and that reticulopodial shape can be altered by modifying cell-substrate adhesion. Allogromia laticollaris was cultured in 26‰ salinity Føyn’s erdschreiber as described previously ( Travis and Allen, 1981 ). Amphistegina leesonii...

... (University of Rennes), focused on the life cycle of Allogromia laticollaris Arnold, a bright orange, organic-walled foraminiferan that he had isolated from shallow-water algal collections made in 1946 near Panama City, Florida, USA ( Arnold, 1948 , 1955). He showed that the life cycle includes three...

... and others, 2002 ; this volume). © 2002 Journal of Foraminiferal Research 2002 Some organic-walled allogromiids are familiar organisms. For example, the easily cultured species Allogromia laticollaris, and its undescribed relative A. laticollaris NF (new form), have been used extensively...

... and phylogenetically primitive among the Foraminifera ( Tappan and Loeblich, 1988 ). In living material viewed at the level of the light microscope, the test or “shell”, when present, may appear clear (e.g., Allogromia laticollaris, Iridia lucida ), translucent with minor or fine agglutinated material (e.g...

... species on sublittoral bottoms. Jahn and Rinaldi (1959) measured pseudopodial streaming velocities of about 8 to 15 μm per second in Allogromia laticollaris under their observational conditions. Unfortunately, they did not specify what these conditions were nor did they examine the effect...

...” their cytoplasm by egesting foreign items, stercomata, and perhaps other materials (e.g., Jepps, 1942 ). Vegetative individuals of many foraminiferans exhibit a distinctively rich cytoplasmic coloration (e.g., Allogromia laticollaris Arnold, Ammonia tepida, Elphidium spp.), and to some extent this varies...
