Dataset for transcriptomic profiles associated with development of sexual structures in Aspergillus flavus

Area of Science:

• Mycology
• Genomics
• Molecular Biology

Background:

• Transcriptomic data on Aspergillus flavus sexual cycle is limited.
• Understanding A. flavus sexual reproduction is crucial for developing biocontrol strategies against aflatoxigenic strains.

Purpose of the Study:

• To present transcriptomic datasets from A. flavus sclerotia during sexual reproduction.
• To identify genes and gene clusters involved in A. flavus sexual reproduction and fertilization.
• To provide data for further investigation into sclerotia fertility and sexual reproduction in A. flavus.

Main Methods:

• RNA extraction from mated and unmated A. flavus sclerotia at various time points.
• Transcriptomic sequencing using Illumina NovaSeq 6000.
• Bioinformatic analyses including read mapping, differential gene expression, and co-expression network analysis.

Main Results:

• Transcriptomic profiles were generated for A. flavus sclerotia under different fertility conditions and time points.
• Differential gene expression and co-expression networks were analyzed to identify genes related to sexual reproduction.
• Datasets are publicly available for further research and comparison.

Conclusions:

• The study provides valuable transcriptomic data on A. flavus sexual development.
• These data can inform the development of non-toxigenic A. flavus strains for biocontrol.
• Further research can utilize this data to explore the molecular mechanisms of A. flavus sexual reproduction.
