Endopolyploidy Changes with Age-Related Polyethism in the Honey Bee, Apis mellifera
Honey bees (Apis mellifera) exhibit age polyethism, whereby female workers assume increasingly complex colony tasks as they age. While changes in DNA methylation accompany age polyethism, other DNA modifications accompanying age polyethism are less known. Changes in endopolyploidy (DNA amplification in the absence of cell division) with increased larval age are typical in many insect cells and ...
متن کاملHeterosis 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 کاملOxidative Enzyme Systems of the Honey Bee, Apis Mellifera L
1. Oxidative dissimilation has been studied in enzymes from the honey bee. Using mitochondria isolated from the thoraces, complete oxidation of most of the TCA cycle members has been shown. 2. The presence of the acetate-activating enzyme, citrate-condensing enzyme, isocitric dehydrogenase, alpha-ketoglutarate dehydrogenase, glucose-6-phosphate, and 6-phosphogluconic dehydrogenase has been demo...
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 کاملHygienic behavior in the honey bee (Apis mellifera L.) and the modulatory role of octopamine.
Honey bees, Apis mellifera, which perform hygienic behavior, quickly detect, uncap and remove diseased brood from the nest. This behavior, performed by bees 15-20 days old and prior to foraging, is likely mediated by olfactory cues. Because the neuromodulator octopamine (OA) plays a pivotal role in olfactory-based behaviors of honey bees, we examined whether bees bred for hygienic and nonhygien...
