Map of dimorphic switching‑related signaling pathways in based on its transcriptome.

) induces sporotrichosis, which has gained attention in recent years due to its worldwide prevalence. The dimorphic switching process is essential for the pathogenesis of . Previously, overexpression of several signal transduction genes, including SsDRK1 and SsSte20, was observed during the mycelium‑to‑yeast transition; these were necessary for asexual development, yeast‑phase cell formation, cell wall integrity and melanin synthesis. However, the mechanisms of the signaling pathways during dimorphic switching of remain unclear. In the present study, transcriptome sequencing of the 48‑h induced yeast forms and mycelium of was performed. In total, 24,904,510 high‑quality clean reads were obtained from mycelium samples and 22,814,406 from 48‑h induced yeast form samples. Following assembly, 31,779 unigene sequences were obtained with 52.98% GC content (The proportion of guanine G and cytosine C to all bases in nucleic acid). The results demonstrated that 12,217 genes, including genes involved in signal transduction and chitin synthesis, were expressed differentially between the two stages. According to these results, a map of the signaling pathways, including two‑component and heterotrimeric G‑protein signaling systems, Ras and MAPK cascades associated with the dimorphic switch, was drawn. Taken together, the transcriptome data and analysis performed in the present study lay the foundation for further research into the molecular mechanisms controlling the dimorphic switch of and support the development of anti‑ strategies targeting genes associated with signaling pathways.
