“…One example is the characterization of the neo-XY body of C. perspicillata by using C. brevicauda probes on meiotic preparations [Noronha et al, 2009]. In the case of the vespertilionid genus Scotophilus , G-band comparison could not resolve the composition of 3 rearranged chromosomal pairs.…”

Chiroptera, the second largest order of mammals, comprises more than 1,000 species in 18 highly morphologically diverse families. Chromosome painting with human probes has been applied to 10 bat species from 8 families. Except for the combination 10/12pq/22q, all syntenic segmental associations proposed for the mammalian ancestor have been found in Chiroptera. Bat-specific painting probes, established from 4 species of 3 families, have been used in whole chromosome painting experiments in 29 species from 8 families. The results show that the prevailing mode of chromosomal evolution in bats is Robertsonian translocation with a large number of convergent events. Given our present knowledge of chiropteran karyotypes, only a few elements of the ancestral chiropteran karyotype can be reconstructed with confidence.

“…The frequent chromatin compaction in the XY body can be modified in species with a multiple (XX/ XY 1 Y 2 ) chromosomal sex determination system (Solari 1994;Noronha et al 2009). There are species with a compound (neo-XX/XY) sex determination system which presents a typical XY body, as in the house musk shrew Suncus murinus and some bats (Solari 1994;Noronha et al 2001).…”

“…BrdU incorporation data confirm that the autosomal segment shows early replication, even when translocated to the latereplicating X (Kasahara and Dutrillaux 1983).

“…Pieczarka et al (2005) produced probes from the karyotypes of two bat species (C. brevicauda and Phyllostomus hastatus), which allowed them to identify the autosomes (PHA2 and 5) involved in the evolution of the sex determination system (XX/ XY 1 Y 2 ). Later, this study was followed by the meiotic analysis in Carollia by Noronha et al (2009). In the present paper, we used these probes to analyze the meiotic behavior of the sex chromosomes of three species of Phyllostomidae, including one with the XY system and two with a compound neo-XX/XY.…”

Meiotic analysis of XX/XY and neo-XX/XY sex chromosomes in Phyllostomidae by cross-species chromosome painting revealing a common chromosome 15-XY rearrangement in Stenodermatinae

et al. 2010

We analyzed the meiotic behavior of the sex chromosomes of the bats Glossophaga soricina (XX/XY), Artibeus cinereus and Uroderma magnirostrum (neo-XX/XY) using multicolor FISH. The X chromosome and pair 15 autosome probes are from Phyllostomus hastatus and the Y from Carollia brevicauda. On both species with the neo-XX/XY system, the autosome translocated to the sex chromosomes is the pair 15 in P. hastatus, a synapomorphy. The analysis of meiosis confirms that the X and Y have a pseudo-autosomal region, with a typical end-to-end pairing. The autosomal regions of the neo-XX/XY shows different levels of condensation when compared to the original XX/XY. The compound system presented a characteristic shape, as if it was a closed ring with a tail. The ring represents the non-paired segments of the X and Y and the small pairing region of the original sex chromosomes. The tail corresponds to the pairing of the 15 P. hastatus autosomal bivalent, which are translocated to the sex chromosomes. Probably the non-pairing is responsible for the meiotic silencing of these segments.

Among species of the Chiroptera, spermatogenesis and the fully differentiated spermatozoa differ in morphological and ultrastructural detail. This study therefore aimed to ultrastructurally characterize the spermatogenesis and the spermatozoa of Carollia perspicillata (Phyllostomidae) and compare the process with other species of bats and mammals. The differentiation of spermatogonia is similar to other bats and to Primates, with three main spermatogonia types: Ad, Ap, and B. Meiotic divisions proceed similarly to those of most mammals and spermiogenesis is clearly divided into 12 steps, in the middle of the range of developmental steps for bats (9-16 steps). The process of acrosome formation is similar to that found in Platyrrhinus lineatus, with the acrosome formed by two different types of proacrosomal vesicles. The ultrastructure of the spermatozoon is similar to other bats already described and resembles the typical mammalian sperm model; however, its morphology differs from other mammals such as marsupials and rodents, on account of a simpler spermatozoon head morphology, which indicates a pattern that is more closely related to the sperm cells of humans and other primates. Our data demonstrated that spermatogenesis in C. perspicillata presents great ultrastructural similarities to P. lineatus. This pattern is not surprising, because both species belong to the same family (Phyllostomidae); however, it is observed that C. perspicillata presents some characteristics that are more closely related to phylogenetically distant species, such as Myotis nigricans (Vespertilionidae), which is a fact that deserves attention.
