Proteomic analysis of honey. Identification of unique peptide markers for authentication of NZ mānuka (Leptospermum scoparium) honey.

Bong Jessie J Middleditch Martin M Loomes Kerry M KM Stephens Jonathan M JM

Food chemistry 20201102

Proteomics is an emerging tool in food authentication that has not been optimised for honey analysis. In this study, we present a qualitative proteomic analysis of New Zealand mānuka (Leptospermum scoparium) honey. A total of fifty bee-derived proteins were identified in the honey, the most predominant being major royal jelly proteins (MRJPs). We also demonstrate for the first time the presence of unique nectar-derived proteins in mānuka honey. A total of 17 mānuka plant proteins were identified ...[more]

Characterization of loquat (Eriobotrya japonica Lindl.) honey botanical origin according to its chitinase activity

Project description:Bees make honey from the nectar that they collect from flowers. The characteristics of honey are closely associated to original botanical species. Compare with sugars in honey, proteins are minor components but usually used as an important honey quality evaluation parameters. Flower-origin proteins could be a good marker for the authentication. However, as a minute component in honey proteome, plant origin proteins are hard to be detected in honey by regular proteomic approaches, such as gel-based techniques. In this study, Eriobotrya japonica Lindl. (loquat) nectar and its derivative monofloral honey were systematically compared, especially regarding the proteomes and enzymatic activities. Using two-dimensional electrophoresis and mass spectrometry, only bee-originated proteins were detected in loquat honey which were major royal jelly proteins and two uncharacterized proteins. Xylosidase, thaumatin, and two kinds of chitinases were detected in loquat floral nectar by the gel-based proteomic approach. To our knowledge, it is the first study to analysis nectar-originated enzymes’ activity in honey and we proposed that the zymography of chitinase is a potential marker for honey botanical origin authentication.

Brain transcriptomics of honey bee parasitized by Varroa destructor or Nosema ceranae

Project description:In this study we addressed whether the transcriptome profile in the honey bee brain is similar for two major parasites of honey bee, Varroa destructor and Nosema ceranae. Honey bees parasitized by these two parasites show accelerated behavioral maturation and deficiences in orientation and learning/memory that we hoped to characterized at the transcriptomic level. honey bee adults infested by Varroa destructor or Nosema ceranae compared to control bees, in duplicate

Proteomic comparison of summer and winter Apis mellifera workers shows reduced protein abundance in winter samples

Project description:Apis mellifera workers in temperate climates display two castes; short lived summer bees that engage in nursing, hive maintenance and foraging, and long lived winter bees (diutinus bees) which remain within the hive and are essential for thermoregulation. Label free quantitative proteomic analysis was conducted on A. mellifera workers sampled in June and December to compare the proteomes of summer and winter bees. Proteomic analysis was completed on head, abdominal and venom sac samples which revealed an elevated level of protein abundance in summer bees but and a decrease in protein abundance in winter bees. Head and abdominal samples displayed an increase in cuticular proteins in summer samples whereas an increase in xenobiotic proteins was observed in winter samples. Several carbohydrate metabolism pathways which have been linked to energy production and longevity in insects were observed to be increased in abundance in winter samples in comparison to summer samples. Proteomic analysis of the venom sacs an increased abundance and expression of bee venom associated proteins in comparison to winter workers. These data provides an insight into the adaptions of A. mellifera workers in summer and winter and may aid in future treatment and disease studies on honeybee colonies.

Nutrigenomics in honey bees: the impact of pollen nutrients on bee health

Project description:We studied the molecular mechanisms underlying the impact of pollen nutrients on honey bee (Apis mellifera) health and how those nutrients improve resistance to parasites. Using digital gene expression, we determined the changes in gene expression induced by pollen intake in worker bees parasitized or not by the mites Varroa destructor, known for suppressing immunity and decreasing lifespan of bees. bees with or without verroa, and fed or not fed pollen

Flenniken_BeeArray2_2012

Project description:Flenniken - Honey bee gene expression microarray experimental design<br>To minimize variability between samples all arrayed bees were obtained from a single brood comb from a naturally mated queen, therefore all the bees were age-matched half-sisters. The bees selected for microarray analysis of virus (Sindbis-eGFP) co-injected with either virus-specific-dsRNA (vs-dsRNA) or non-specific dsRNA (ns-dsRNA) exhibited the reduced virus phenotype that was seen in the majority of the bees assayed. The five representative bees from each condition (v, v+vs-dsRNA, v+ns-dsRNA, dsRNA, and mock/injected with buffer) selected for microarray analysis were free of pre-existing conditions (assessed by APM analysis) (Runckel, Flenniken et al., 2011). To facilitate gene expression comparisons between multiple treatment groups we utilized a reference-design strategy in which each Cy5-labeled experimental sample was hybridized with a standardized Cy3-labeled reference sample. A complex RNA mixture representing hundreds of bees of various ages exposed to difference treatment groups, served as the reference RNA sample.

Characterization of a L-Gulono-1,4-Lactone Oxidase Like Protein in the Floral Nectar of Mucuna sempervirens, Fabaceae.

Project description:Floral nectar plays important roles in the interaction between animal-pollinated plants and pollinators. Growing empirical evidence shows that most of the proteins secreted in nectar (nectarins) are enzymes that can tailor nectar chemistry for their animal mutualists or reduce the growth of microorganisms in nectar. However, to date, the function of many nectarins remains unknown, and very few plant species have had their nectar proteome thoroughly investigated. Mucuna sempervirens (Fabaceae) is a perennial woody vine native to China. Nectarins from this species were separated using two-dimensional gel electrophoresis, and analyzed using mass spectrometry. A L-gulonolactone oxidase like protein (MsGulLO) was detected. MsGulLO has high similarity to L-gulonolactone oxidase 5 (AtGulLO5) in Arabidopsis thaliana, which was suggested to be involved in the pathway of ascorbate biosynthesis; however both MsGulLO and AtGulLO5 are divergent from animal L-gulonolactone oxidases. MsGulLO is suggested to function in hydrogen peroxide generation in nectar but not in plant ascorbate biosynthesis.
