Abstract :
Ascosphaera apis, a specialized fungal pathogen, causes lethal infection in honeybee larvae. miRNA-like small RNAs (milRNAs) are fungal small non-coding RNAs similar to miRNAs, which have been shown to regulate fungal hyphal growth, spore formation, and pathogenesis. Based on the transcriptome data, differentially expressed miRNA-like RNAs (DEmilRNAs) in A. apis infecting the Apis cerana cerana worker 4-, 5-, and 6-day-old larvae (Aa-4, Aa-5, and Aa-6) were screened and subjected to trend analysis, followed by target prediction and annotation as well as investigation of regulatory networks, with a focus on sub-networks relative to MAPK signaling pathway, glycerolipid metabolism, superoxide dismutase, and enzymes related to chitin synthesis and degradation. A total of 606 milRNAs, with a length distribution ranging from 18 nt to 25 nt, were identified. The first nucleotide of these milRNAs presented a bias toward U, and the bias patterns across bases of milRNAs were similar in the aforementioned three groups. There were 253 milRNAs, of which 68 up-and 54 down-regulated milRNAs shared by these groups. Additionally, the expression and sequences of three milRNAs were validated by stem-loop RT-PCR and Sanger sequencing. Trend analysis indicated that 79 DEmilRNAs were classified into three significant profiles (Profile4, Profile6, and Profile7). Target mRNAs of DEmilRNAs in these three significant profiles were engaged in 42 GO terms such as localization, antioxidant activity, and nucleoid. These targets were also involved in 120 KEGG pathways including lysine biosynthesis, pyruvate metabolism, and biosynthesis of antibiotics. Further investigation suggested that DEmilRNA-targeted mRNAs were associated with the MAPK signaling pathway, glycerolipid metabolism, superoxide dismutase, and enzymes related to chitin synthesis and degradation. Moreover, the binding relationships between aap-milR10516-x and ChsD as well as between aap-milR-2478-y and mkh1 were confirmed utilizing a combination of dual-luciferase reporter gene assay and RT-qPCR. Our data not only provide new insights into the A. apis proliferation and invasion, but also lay a basis for illustrating the DEmilRNA-modulated mechanisms underlying the A. apis infection.

Abstract :
Apoptosis is a genetically controlled process vital for homeostasis. This study examined the apoptotic response in the gut of Apis mellifera (A. mellifera) larvae to infection by Ascosphaera apis (A. apis) and its impact on host resistance and pathogen virulence. Here, Worker larvae of A. mellifera were inoculated with purified A. apis spores. We then quantified the expression of key apoptosis-related genes (AmCaspase-3, AmBax, and AmBcl-2) in the host gut and detected apoptotic cells via TUNEL assay. To functionally assess the role of apoptosis, larvae were treated with either the apoptosis inhibitor Z-VAD-FMK or the activator PAC-1, after which host survival, expression of apoptosis-associated genes, and the fungal virulence factor gene Ste11-like were analyzed. Our results showed that infection with A. apis significantly upregulated the expression of AmCaspase-3 and AmBax (p < 0.05) at 1-3 days post-inoculation (dpi), while the expression of AmBcl-2 was significantly reduced at 1 and 3 dpi (p < 0.05). Consistent with this, TUNEL assays revealed a markedly stronger green fluorescence signal in the guts of inoculated larvae at 3 dpi compared to uninfected controls, with clear co-localization of TUNEL and nuclear signals, confirming increased apoptosis. Pharmacological inhibition of apoptosis significantly enhanced the survival rate of A. apis-infected larvae, whereas apoptosis activation decreased larval survival. Accordingly, inhibiting apoptosis significantly suppressed the expression of AmCaspase-3 and AmBax (p < 0.001) and upregulated AmBcl-2 (p < 0.001). Conversely, apoptosis activation upregulated AmCaspase-3 (p > 0.05) and AmBax (p < 0.001), while significantly down-regulating AmBcl-2. Furthermore, apoptosis inhibition significantly down-regulated the fungal virulence gene Ste11-like, while its activation had the opposite effect. In summary, A. apis infection induces apoptosis in the larval gut by activating AmCaspase-3 and AmBax and suppressing AmBcl-2. Inhibiting this apoptotic response enhanced host survival by modulating the expression of host apoptosis-related genes and the fungal Ste11-like virulence factor. These findings provide new insights into the host response to A. apis and suggest a potential strategy for controlling chalkbrood disease.
