Sex Determination in the Honeybee
Sex determination in honeybees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females. In this issue of Cell, report the cloning of the sex-determining gene, csd. It codes for an SR protein, and different alleles have very different amino-acid sequences. Inactivating csd leads to development as a male.

متن کاملContrasting Sex-and Caste-Dependent piRNA Profiles in the Transposon Depleted Haplodiploid Honeybee Apis mellifera
Protecting genome integrity against transposable elements is achieved by intricate molecular mechanisms involving PIWI proteins, their associated small RNAs (piRNAs), and epigenetic modifiers such as DNA methylation. Eusocial bees, in particular the Western honeybee, Apis mellifera, have one of the lowest contents of transposable elements in the animal kingdom, and, unlike other animals with a ...
متن کاملThe Therapeutic Effects of Bioactive Compounds in Honeybee Products
Honey, royal jelly, propolis, and bee pollen are potentially beneficial to humans due to their bioactive agents. Different molecules of these honeybee products have been extracted and pharmacologically characterized. Phenolic acid, Major Royal Jelly Proteins (MRJPs), and oligosaccharides are major bioactive substances of these products. Propolis, especially Brazilian type, contains caffeic acid...
