Genes (Basel) 2021; 12:1358. [PMID: 34573341 PMCID: PMC8465153 DOI: 10.3390/genes12091358] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 08/16/2021] [Accepted: 08/27/2021] [Indexed: 01/22/2023] Open
Abstract
We analyzed the synapsis and recombination between Z and W chromosomes in the oocytes of nine neognath species: domestic chicken Gallus gallus domesticus, grey goose Anser anser, black tern Chlidonias niger, common tern Sterna hirundo, pale martin Riparia diluta, barn swallow Hirundo rustica, European pied flycatcher Ficedula hypoleuca, great tit Parus major and white wagtail Motacilla alba using immunolocalization of SYCP3, the main protein of the lateral elements of the synaptonemal complex, and MLH1, the mismatch repair protein marking mature recombination nodules. In all species examined, homologous synapsis occurs in a short region of variable size at the ends of Z and W chromosomes, where a single recombination nodule is located. The remaining parts of the sex chromosomes undergo synaptic adjustment and synapse non-homologously. In 25% of ZW bivalents of white wagtail, synapsis and recombination also occur at the secondary pairing region, which probably resulted from autosome-sex chromosome translocation. Using FISH with a paint probe specific to the germline-restricted chromosome (GRC) of the pale martin on the oocytes of the pale martin, barn swallow and great tit, we showed that both maternally inherited songbird chromosomes (GRC and W) share common sequences.

Abstract
In this study, we analyzed 93 whole genomes from Chinese spot-billed ducks (CSB), meat-type ducks (MET), and egg and dual purpose-type ducks (EDT) to characterize the genetic material flowing between the CSB and modern ducks. Using a frequency of shared identical-by-descent method, approximately 10.9 Mb introgression segments containing 140 genes were identified showing the signatures of introgression between CSB and EDT. Meanwhile, nearly 10.6 M introgression regions containing 149 genes were identified between CSB and MET. Based on the haplotypes tree of each segment, we found that the introgression between CSB and domesticated ducks was asymmetric with a high level of gene flow from domestic to CSB and a low level of migration in the opposite direction. Moreover, we identified several genes that were introgressions from CSB and showed the signature of positive selection, which may contribute to the breeding of modern ducks. Our results provide new insight into the evolution and breeding history of domestic ducks and may be useful for the future management of wild and domestic duck populations.

[PMID: 30793238 DOI: 10.1007/s00412-019-00693-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 01/11/2019] [Accepted: 02/11/2019] [Indexed: 12/27/2022]
Abstract
The synaptonemal complex is an evolutionarily conserved, supramolecular structure that holds the homologous chromosomes together during the pachytene stage of the first meiotic prophase. Among vertebrates, synaptonemal complex dynamics has been analyzed in mouse spermatocytes following the assembly of its components from leptotene to pachytene stages. With few exceptions, a detailed study of the disassembly of SCs and the behavior of SC components at recombination sites at the onset of diplotene has not been accomplished. Here, we describe for the first time the progressive disassembly of the SC in chicken oocytes during the initial steps of desynapsis using immunolocalization of specific SC proteins and super-resolution microscopy. We found that transverse filament protein SYCP1 and central element component SYCE3 remain associated with the lateral elements at the beginning of chromosomal axis separation. As the separation between lateral elements widens, these proteins eventually disappear, without any evidence of subsequent association. Our observations support the idea that post-translational modifications of the central region components have a role at the initial phases of the SC disassembly. At the crossover sites, signaled by persistent MLH1 foci, the central region proteins are no longer detected when the SYCP3-positive lateral elements are widely separated. These findings are indicative that SC disassembly follows a general pattern along the desynaptic bivalents. The present work shows that the use of avian oocytes at prophase I provides a valuable model to explore the time course and chromosomal localization of SC proteins and its relationship with local changes along meiotic bivalents.
