Pre‐oviposition development of the brown anole (Anolis sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Evolution of trans-Andean endemic fishes of the genus Cheirodon (Teleostei: Characidae) are associated with chromosomal rearrangements

Revista Chilena de Historia Natural, 2018
Background Among Neotropical fishes, the family Characidae is highly diverse and speciose and its taxonomy is not completely resolved. In Chile, the family is represented by five species, all within the genus Cheirodon, of which C.

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

Developmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Description of the karyotype of Rhagomys rufescens Thomas, 1886 (Rodentia, Sigmodontinae) from Southern Brazil Atlantic forest

Genetics and Molecular Biology, 2010
Rhagomys rufescens (Rodentia: Sigmodontinae) is an endemic species of the Atlantic forest from Southern and Southeastern Brazil. Some authors consider Rhagomys as part of the tribe Thomasomyini; but its phylogenetic relationships remain unclear ...

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Species and sex comparisons of karyotype and genome size in two Kurixalus tree frogs (Anura, Rhacophoridae)

Acta Herpetologica, 2017
Kurixalus is a rhacophorid genus of tree frogs that are similar in morphology but vary in reproductive behavior. We investigated the cytogenetic features and genome size using conventional G-banding, C-banding and silver-staining techniques, fluorescence

Overexpression of rRNA genes in a patient with intellectual disability and familial 13p+ chromosome

Бюллетень сибирской медицины, 2018
A study of a child with intellectual disability revealed an enlarged p-arm in chromosome 13 and amplified rDNA. qRT-PCR showed an approximately 6-fold increased level of rRNA in the patient’s blood samples.
