Cytological studies in the Musae; meiosis in some diploid clones.

HE banana breeding program currently being carried out in Jamaica T is largely based on the progeny of the triploid (zn=33) Gros Michel crossed with a number of naturally occurring diploids. The bulk of such progeny have been found to be tetraploid (LARTER 1935 and unpublished; CHEESMAN and DODDS 1942), which suggests that Gros Michel has a tendency to throw a majority of triploids among its vi...

Cytological studies of recombination in rhesus males.

An immunofluorescence approach was used to directly examine meiotic recombination events in 483 pachytene spermatocytes from 11 male rhesus monkeys. Specifically, we examined the nuclear localization patterns of the DNA mismatch repair protein MLH1, known from analyses of other mammalian species to be a useful marker of meiotic cross-overs. Our results indicated that rhesus pachytene spermatocy...

Cytological Studies of the Nematocysts of Hydra

Entire hydras or tentacles were fixed in OsO(4) or in KMnO(4) and thereafter washed, dehydrated, and embedded in a methacrylate mixture. Ultrathin sections were cut on an experimental model, thermal expansion type ultramicrotome or on a Porter-Blume microtome. The sections were examined in an RCA electron microscope. Type EMU-2 D. "Squash preparations" for light microscopy, were made from the h...

Some cultural and cytological characteristics of human tumors in vitro.

The present study was undertaken to determine both the general growth patterns and some of the cytological details of frequently occurring human tumors. For this purpose the roller tube method, which provides good nutritional conditions, and the hanging drop method, which, less favorable nutritionally, provides optimal conditions for cytological investigation, were used. The cultural behavior o...
