Transcriptional divergence among different mating-type strains and their cross of Morchella sextelata during the asexual stage.
Transcriptional divergence reveals that MAT1-2 exhibits greater dynamism during conidiation, while MAT1-1 gains influence in crosses of Morchella sextelata.
- Why it matters: Understanding mating-type gene regulation in fungi like M. sextelata is crucial for insights into their reproductive biology and potential cryptic sexual processes during asexual stages.
- What they did: The study analyzed genome-wide transcriptomes of MAT1-1, MAT1-2, and their cross during conidiation, identifying significant transcriptional differences and interactions among MAT genes.
- The result: Findings show divergent transcriptional capacities between MAT types and activation of additional MAT genes in crosses, suggesting hidden sexual elements during asexual development.
