The leptotene stage, also known as leptonema, is the first of five substages of prophase I during meiosis, the specialized cell division that reduces the chromosome number by half to produce haploid gametes in sexually reproducing organisms.

The first stage of prophase I is the leptotenestage, also known as leptonema, from Greek words meaning "thin threads".: 27 In this stage of prophase...

identity for each homologous pairs. They appear as dense granules during leptotenestage There are more than 2000 chromomeres on 20 chromosomes of maize. Chromomeres...
quickly complete meiosis I prior to ovulation. In the first stage of prophase I, leptotene (from the Greek for "delicate"), chromosomes begin to condense...
mechanism of DNA repair acting during meiosis. From the leptotene to early pachytene stages of meiosis exogenous damage triggered the massive presence...
whereas DNA repair is not detectable in the pre-dictyate (leptotene, zygotene and pachytene) stages of meiosis. For those primary oocytes that continue to...

diplotene) stage of meiosis actively repairs DNA damage, whereas DNA repair was not detected in the pre-dictyate (leptotene, zygotene and pachytene) stages of...
meiosis initiation; however, they cannot complete the process. Mutations in leptotene spermatocytes can result in premature chromosome condensation. Mutations...

expressed in spermatogonia, pre-leptotene spermatocytes, and in spermatocytes in the leptotene, zygotene and early pachytene stages of meiosis. In synaptonemal...
involved in the expansion of H2AX phosphorylation during the leptotene to pachytene stages of meiosis. HAT domains for this family are approximately 250...
early stages of meiosis (leptotene-early zygotene stages) caused a significant increase in chiasmata frequency when scored at the later stages (diplotene-diakinesis...

spermatogonia, preleptotene spermatocytes, and spermatocytes in the meiotic stages of leptotene, zygotene and early pachytene are enriched for FANC proteins. This...
autosomal chromosomes are transcriptionally active during the leptotene to zygotene stages of meiosis, whereas the X chromosome is inactive throughout meiosis...
