摘要:

为探究以色列急性麻痹病毒(Israeli acute paralysis virus, IAPV)对意大利蜜蜂(Apis mellifera ligustica)蜂王浆分泌的影响,在确认其偏好感染咽下腺和上颚腺的基础上,对新出房工蜂分别饲喂含3种不同浓度IAPV的蔗糖溶液。通过转录组测序初步分析病毒对工蜂蜂王浆分泌的影响,并采用RT-qPCR和液相色谱法分别检测蜂王浆主蛋白(major royal jelly protein, mrjp)基因的相对表达量和10-羟基-2-癸烯酸(10-HDA)的含量。结果显示:外源接种高浓度病毒显著降低工蜂存活率,其中位生存期仅为16.5 d,并显著影响工蜂头部的蛋白质合成与脂肪酸合成相关通路。RT-qPCR和液相色谱结果进一步表明,在第18天,与对照组相比,接种高浓度病毒的工蜂mrjp1基因相对表达量下降96%,每只工蜂的10-HDA含量降低11.98 μg。以上结果说明,IAPV通过抑制蜂王浆主蛋白与脂肪酸的合成,进而影响蜂王浆的分泌。

Abstract:

To investigate the impact of Israeli acute paralysis virus (IAPV) on royal jelly production in Apis mellifera ligustica, newly emerged worker bees were fed sucrose solutions containing three different concentrations of IAPV, following confirmation of the virus’s preferential infection of the hypopharyngeal and mandibular glands. Transcriptome sequencing was first employed to preliminarily assess the virus’s effects on royal jelly secretion. Subsequently, RT-qPCR and liquid chromatography were used to measure the relative expression levels of major royal jelly protein (mrjp) genes and the content of 10-hydroxy-2-decenoic acid (10-HDA), respectively. The results showed that high-concentration viral inoculation significantly reduced worker bee survival rates, with a median lifespan of only 16.5 days, and markedly disrupted protein and fatty acid synthesis pathways in the bees’ heads. Further analysis by RT-qPCR and liquid chromatography revealed that, by day 18, high-concentration viral infection led to a 96% decrease in mrjp1 gene expression and an 11.98 μg reduction per bee in 10-HDA content. These findings demonstrate that IAPV impairs royal jelly secretion by suppressing the synthesis of major royal jelly proteins and fatty acids.
