Nanopore long-read transcriptome data of fungal pathogen of chalkbrood disease, Ascosphaera apis

Ascosphaera apis is a fungal pathogen that exclusively infects honeybee larvae, leading to chalkbrood disease, which damages the number of adult honeybees and colony productivity. In this article, A. apis mecylia and spores were respectively purified followed by Oxford Nanopore sequencing via PromethION platform. In total, 6,321,704 and 6,259,727 raw reads were generated from Aam and Aas, with a length distribution among 1 kb~10 kb. The quality (Q) scores of majority of raw reads were Q9 (Aam) and Q11 (Aas).

Additionally, 5,669,436 and 6,233,159 clean reads were gained, among them 79.32% and 79.62% were identified as being full-length. The lengths of redundant reads-removed full-length transcripts were among 1 kb~8 kb and 1 kb~9 kb, and most abundant length for both was 1 kb. Furthermore, the length of redundant transcripts-removed clean reads was ranged from 1 kb~7 kb, with the largest group of 1 kb.

The data reported here provides a beneficial genetic resource for improving genome and transcriptome annotations of A. apis and for exploring alternative splicing and polyadenylation of A. apis mRNAs.
