Objective: In several nations, royal jelly is used in apitherapy, healthful foods, and cosmetics. The production quality of collected from honeybee colonies are being worked on by researchers beekeepers. This study investigated the effect honey pollen substitute feeding efficiency jelly. addition, analyses were conducted to determine differences between fed unfed groups terms 10-hydroxy-2-decon...

In Solanaceae, the S-specific interaction between the pistil S-RNase and the pollen S-Locus F-box protein controls self-incompatibility (SI). Although this interaction defines the specificity of the pollen rejection response, the identification of three pistil essential modifier genes unlinked to the S-locus (HT-B, 120K, and NaStEP) unveils a higher degree of complexity in the pollen rejection ...

Maize (Zea mays) pollen is highly nutritious and can be used by predatory arthropods to supplement or replace a carnivorous diet. We demonstrate that maize pollen can be utilized by larvae of the green lacewing, Chrysoperla carnea (Neuroptera: Chrysopidae) under laboratory conditions. Complete development on maize pollen was not possible, but 25% of neonates reached the third instar. When only ...

The role of heterotrimeric G proteins in pollen germination, tube growth, and signal transduction of extracellular calmodulin (CaM) was examined in lily pollen. Two kinds of antibodies raised against animal Gzalpha, one against an internal sequence and the other against its N terminus, cross-reacted with the same 41-kD protein from lily pollen plasma membrane. This 41-kD protein was also specif...

this research was conducted to evaluate the effects of feeding fermented diets as a protein supplement, using different diets in a completely randomized design with 6 treatments and 7 replications per treatment for 50 days in apiary in karaj area. honey bee colonies were assimilated in terms of honey, population and same age sister queen. experimental treatments included: 1. fermented gluten me...

Higher protein content and greater taxonomic richness of pollen have been noted as beneficial for bee health, but the relationship between well how varies across landscape gradients remain understudied. We assessed correlations plant species composition in collected from honey colonies three states over 2 years. selected sites along an agricultural-grassland gradient to investigate varied with ...

The nutritional composition of food is often complex as resources contain a plethora different chemical compounds, some them more, less meaningful to consumers. Plant pollen, major source for bees, particular importance it comprises nearly all macro- and micronutrients required by bees successful development reproduction. However, perceiving evaluating nutrients may be tedious impair quick fora...

Exhibiting rapid polarized growth, the pollen tube delivers the male gametes into the ovule for fertilization in higher plants. To get an overall picture of gene expression during pollen germination and pollen tube growth, we profiled the transcription patterns of 1,536 pollen cDNAs from lily (Lilium longiflorum) by microarray. Among those that exhibited significant differential expression, a c...

in order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in isfahan region. protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and pollen. results showed that the longevi...

Tobacco mature pollen has extremely desiccated cytoplasm, and is metabolically quiescent. Upon re-hydration it becomes metabolically active and that results in later emergence of rapidly growing pollen tube. These changes in cytoplasm hydration and metabolic activity are accompanied by protein phosphorylation. In this study, we subjected mature pollen, 5-min-activated pollen, and 30-min-activat...
