As the only truly domesticated insect, the silkworm not only has great economic value, but it also has value as a model for genetics and molecular biology research. Genomics and proteomics have recently shown vast potential to be essential tools in domesticated silkworm research, especially after the completion of the Bombyx mori genome sequence. This paper reviews the progress of the domestica...

After the identification of 5-10% of trans-unsaturated acids, mainly elaidic (trans-octadec-9-enoic) and vaccenic (trans-octadec-11-enoic), in ox fat (Swern, Knight & Eddy, 1952), it has been shown in this Laboratory (Hartman, Shorland & McDonald, 1954, 1955) that substantial amounts of these acids appear in the depot fats of other ruminants (3-5-11-2 %) and in certain marsupials (18-1-21-0 %),...

Citron (Citrus medica L.) is a medicinally important species of citrus native to India and occurs in natural forests and home gardens in the foothills of the eastern Himalayan region of northeast India. The wild populations of citron in the region have undergone rapid decline due to natural and anthropogenic disturbances and most of the remaining individuals of citron are found in fragmented na...

The biological antagonism between copper and molybdenum was discovered when cattle grazing pastures high in Mo were found to develop a syndrome characterized by diarrhoea, growth retardation, anaemia and achromotrichia, which could be prevented by administering Cu. This syndrome was subsequently reproduced in non-ruminants, but further studies revealed important differences in the nature of the...

We have investigated the phylogenetic relationships among six wild and six domesticated taxa of Cucurbita using as a marker an intron region from the mitochondrial nad1 gene. Our study represents one of the first successful uses of a mtDNA gene in resolving inter- and intraspecific taxonomic relationships in Angiosperms and yields several important insights into the origins of domesticated Cucu...

Although sunflower was long thought to be the product of a single domestication in what is now the east-central United States, recent archaeological and genetic evidence have suggested the possibility of an independent origin of domestication, perhaps in Mexico. We therefore used hypervariable chloroplast simple-sequence repeat markers to search for evidence of a possible Mexican origin of dome...
