Identification of a micropeptide and multiple secondary cell genes that modulate Drosophila male reproductive success

C Immarigeon, Y Frei, SYN Delbare… - Proceedings of the …, 2021 - National Acad Sciences
Even in well-characterized genomes, many transcripts are considered noncoding RNAs
(ncRNAs) simply due to the absence of large open reading frames (ORFs). However, it is …

Transcriptional programs are activated and microRNAs are repressed within minutes after mating in the Drosophila melanogaster female reproductive tract

SYN Delbare, AM Jain, AG Clark, MF Wolfner - BMC genomics, 2023 - Springer
Background The female reproductive tract is exposed directly to the male's ejaculate,
making it a hotspot for mating-induced responses. In Drosophila melanogaster, changes in …
