| evolution of gc content in the histone gene repeating units from drosophila lutescens, d. takahashii and d. pseudoobscura. | a subset of histone genes (h1, h2a, h2b and h4), which are encoded along with h3 within repeating units, were analyzed in drosophila lutescens, d. takahashii and d. pseudoobscura to investigate the evolutionary mechanisms influencing this multigene family and its gc content. nucleotide divergence among species was more marked in the less functional regions. a strong inverse relationship was observed between the extent of evolutionary divergence and gc content within the repeating units; this fin ... | 2016 | 27021916 |
| [genetic study of ovary development in drosophila lutescens]. | experiments were carried out in order to clarify the genetic mechanism governing the development of ovaries of drosophila lutescens female flies. female flies of two strains obtained from northern (niigata) and southern (tokunoshima) parts of japan, f1, f2, and backcrossed hybrids were examined. female flies, one week after emergence at 14 degrees c, during which time they were kept under a 10 h 30 min light/13 h 30 min dark regimen, were dissected, and they were divided into three classes: thos ... | 1989 | 2601597 |
