Heterosis in the Honey Bee (Apis Mellifera L.).
HERE are three castes in the honey bee colony: the drone, queen, and worker. T The latter two are both females. The drone bee is a male, representing a haploid gamete of the queen bee heading his hive. The honey bee colony is composed of two generations of bees. The queen bee is, in effect, a potent egg-laying machine, while the workers are morphologically and functionally fitted for honey and ...
متن کاملCytosine modifications in the honey bee (Apis mellifera) worker genome
Epigenetic changes enable genomes to respond to changes in the environment, such as altered nutrition, activity, or social setting. Epigenetic modifications, thereby, provide a source of phenotypic plasticity in many species. The honey bee (Apis mellifera) uses nutritionally sensitive epigenetic control mechanisms in the development of the royal caste (queens) and the workers. The workers are f...
متن کاملSperm storage and antioxidative enzyme expression in the honey bee, Apis mellifera.
Honey bee (Apis mellifera) sperm remains viable in the spermatheca of mated female honey bees for several years. During this time, the sperm retains respiratory activity, placing it at risk of the damaging effects of reactive oxygen species common to many biological processes. Antioxidative enzymes might help reduce this damage. Here we use quantitative real-time RT-PCR to establish gene-expres...
متن کاملDopamine modulation of honey bee (Apis mellifera) antennal-lobe neurons.
Primary olfactory centers [antennal lobes (ALs)] of the honey bee brain are invaded by dopamine (DA)-immunoreactive neurons early in development (pupal stage 3), immediately before a period of rapid growth and compartmentalization of the AL neuropil. Here we examine the modulatory actions of DA on honey bee AL neurons during this period. Voltage-clamp recordings in whole cell configuration were...
متن کاملP 412 Molecular characterisation of honey-bee (Apis mellifera) opsins
@r~ose. The compound eye of the honey-bee, Apis mellifera (L.), possesses retinular cells maximally sensitive to UV, blue and green wavelengths. Behavioumlly, the honey-bee exhibits trichromatic colour vision when searching for food sources and hive location. We therefore set out to sequence the opsins present in the compound eye of the honey-bee and to relate the amino acid sequences to the ph...
