Gland Development

Royal jelly has many important biological functions, however the molecular mechanism of royal jelly secretion in hypopharyngeal gland (HG) is still not well understood. In our previously study, six genes (SV2C, eIF-4E, PDK1, IMP, cell growth-regulating nucleolar protein and TGF-βR1) have been shown to might be associated with royal jelly secretion. In this study, the relative expression levels of these genes were examined in the hypopharyngeal gland of workers at different developmental stages (nurse, forager and reversed nurse stages). The results indicated that the relative expression levels of SV2C, eIF-4E, IMP, cell growth-regulating nucleolar protein and TGF-βR1 were reversed at reversed nurse stage compared to forager stage. We concluded that these genes are possibly candidates related to hypopharyngeal gland development or royal jelly secretion.

The hypopharyngeal gland (HG), along with the mandibular gland from Apis mellifera workers plays a fundamental role on the development of the hive. The protein based substances produced by the hypopharyngeal and mandibular glands are two important component of the royal jelly, which is responsible for caste differentiation and used to feed larvae, drones and the queen. Several factors may alter the physiology of glandular structures in honeybees and consequently their role within the beehive, and one of the most important factors is their nutritional status. However, few studies have evaluated the development of HG against different diets on Africanized honeybees. Our experiment was composed of four diets (treatments) offered to different groups of workers: (T1) honey, (T2) honey + soybean extract, (T3) honey + pollen and (T4) sucrose solution. The development of the glands was evaluated in two periods: 7 and 10 days of exposure to the diet types. According to the results, an interference of the diet on the acini area of the HG was observed. Bees that were fed with the sucrose solution or soybean extract presented the smallest acini areas as compared to the other treatments. The time of exposure to the different types of diets also had an effect on acini areas. Worker bees fed with honey and soybean extract for 10 days presented smaller acini areas when compared to bees dissected at the 7th day of exposure to those same diet types. Nevertheless, we also observed that factors other than just nutrition are important to the full development of the HG, such as the stimulus promoted by the young breeds.

Hypopharyngeal glands of honeybee are age-dependent structures that change with the size of acini and are correlated with various social behaviors. The histochemical structure ofApis ceranaandA. melliferaworker hypopharyngeal glands in four different developmental stages wes stained with ninhydrin Schiff's and periodic acid Schiff's reagents (PAS) for localization of proteins and carbohydrates, respectively, and examined with light microscopy. Nurse bees of both honeybee species had significantly larger glands as compared to guards and forgers, but there were no statistically significant differences between these two species after accounting for caste. Gland protein concentration increased progressively in nurse bees, and this was correlated with the appearance of enriched protein granules in the cytoplasm. In addition, the hypopharyngeal gland protein concentration ofA. melliferawas higher than that ofA. ceranaeven though gland size was not significantly different between species. However, gland size was shown to have decreased progressively in foragers and guards.
