Trichoderma reesei is an economically important enzyme producer with several unique meiotic features. spo11, the initiator of meiotic double-strand breaks (DSBs) in most sexual eukaryotes, is dispensable for T. reesei meiosis.

Plants respond to elevated temperatures by changing gene expression, mediated by transcription factors (TFs) functioning to enhance HS tolerance. The involvement of Group I bZIP TFs in the heat stress response (HSR) is not known.

- Pollen tube growth in flowering plants is guided by secrets from female gametophytes, specifically cysteine-rich proteins (CRPs) that attract pollen tubes through receptor-like kinases.
- Researchers have identified that the Pre-mRNA PROCESSING factor 8 paralogs, PRP8A and PRP8B, play a crucial role in regulating this attraction; mutants lacking these factors fail to properly attract pollen tubes.
- Analysis shows that the PRP8A/PRP8B module is involved in splicing and transcription regulation of key genes necessary for pollen tube attraction, suggesting a complex mechanism of communication between plant cells.
Meiotic double-strand breaks (DSBs) are generated by the evolutionarily conserved SPO11 complex in the context of chromatin loops that are organized along axial elements (AEs) of chromosomes. However, how DSBs are formed with respect to chromosome axes and the SPO11 complex remains unclear in plants. Here, we confirm that DSB and bivalent formation are defective in maize spo11-1 mutants.
