What governs the crucial leptotene-zygotene transition in meiosis? This review explores this pivotal period when homologous chromosomes begin close association, marking a key stage in sexual reproduction. Discussing the bouquet stage, where chromosome ends move into a polarized configuration within the inner nuclear membrane, and the role of chromosome movements, active or passive, also occur. The detailed nature of interhomologue interactions during this period, with special emphasis on the involvement of chromosome ends, and the overall role for meiosis and recombination of chromosome movement and, especially, the bouquet stage are discussed. Interhomologue interactions, particularly those involving chromosome ends, are examined in detail. The review synthesizes current knowledge, offering insights into the intricate orchestration of events driving successful meiotic progression and recombination.
Published in the Annual Review of Genetics, this paper directly addresses a fundamental process within the field of genetics. By synthesizing current knowledge on the leptotene-zygotene transition of meiosis, the review provides a valuable overview of chromosome behavior and interhomologue interactions, aligning with the journal’s focus on genetics and its related molecular mechanisms.
