Preliminary data on the sex ratio in full-sib families of tambaqui Colossoma macropomum. Author(s): VARELA, E. S.; TORATI, L. S.; SILVA, J. J. T.; MACIEL, R. L.; ALMEIDA, F. L.; MORAIS, I. S.; KIRSCHNIK, L. N. G. This preliminary study aimed to investigate the sex ratio in full sib families of C. macropomum to gain insight into the sex determination system and differential growth related to sex. Repository: BDPA Publication year: 2018
A high-density linkage map and sex-linked markers for the Amazon tambaqui Colossoma macropomum. Author(s): VARELA, E. S.; BEKAERT, M.; KIRSCHNIK, L. N. G.; TORATI, L. S.; SHIOTSUKI, L.; O'SULLIVAN, F. L. A.; VILLELA, L. C. V.; REZENDE, F. P.; BARROSO, A. da S.; FREITAS, L. E. L. de; TAGGART, J. B.; MIGAUD, H. Tambaqui (Colossoma macropomum, Cuvier, 1818) is the most economically important native freshwater fish species in Brazil. It can reach a total length of over 1 m and a weight of over 40 kg. The speci... ... Repository: BDPA Publication year: 2021
Estrogen receptors are sex-differentially expressed in tambaqui (Colossoma macropomum) during sex differentiation. Author(s): PAIXÃO, R. V.; SILVA, G. F.; LOBO, I.; YAMAGISHI, M. E. B.; CAETANO, A. R.; VARELA, E. S.; ALMEIDA, F. L. Here we report, for the first time, the identification and initial characterization of ERs and ERRs transcriptional levels in tambaqui (Colossoma macropomum) during sexual differentiation. Repository: BDPA Publication year: 2018
Phylogenomic and expression analysis of Colossoma macropomum cyp19a1a and cyp19a1b and their non-classical role in tambaqui sex differentiation. Author(s): PAIXÃO, R. V.; SILVA, G. F. da; CAETANO, A. R.; CINTRA, L. C.; VARELA, E. S.; O'SULLIVAN, F. L. A. The genes coding for Cytochrome P450 aromatase (cyp19a1a and cyp19a1b) and estrogen (E2) receptors (esr1, esr2a and esr2b) play a conserved role in ovarian differentiation and development among teleos... ...

The tambaqui (Colossoma macropomum) transcriptome at sex differentiation stage. Author(s): LOBO, I.; NASCIMENTO, A.; YAMAGISHI, M.; GUIGUEN, Y.; SILVA, G. F.; ALMEIDA, F. L. As females of tambaqui (Colossoma macropomum) are heavier than males at harvest, farming all-female populations would be more profitable. Unraveling the genetic and physiological mechanisms involved i... ... Repository: BDPA Publication year: 2018
Morphological description of the sex pheromone gland of helicoverpa armigera (Hübner) (Lepidoptera: noctuidae). Author(s): SANTOS, J. S. dos; CORACINI, M. D. A.; KUNZ, R. I.; ROGGIA, S.; BRANCALHÃO, R. M. C. Repository: BDPA Publication year: 2017
An ancient truncated duplication of the anti-Müllerian hormone receptor type 2 gene is a potential conserved master sex determinant in the Pangasiidae catfish family.

F.; ROBINSON-RECHAVI, M.; BOBE, J.; HERPIN, A.; GUIGUEN, Y. The evolution of sex determination (SD) in teleosts is amazingly dynamic, as reflected by the variety of different master sex-determining genes identified. Pangasiids are economically important catfis... ... Repository: BDPA Publication year: 2022

Chromatin structural changes around satellite repeats on the female sex chromosome in Schistosoma mansoni and their possible role in sex chromosome emergence. Author(s): LEPESANT, J. M. J.; COSSEAU, C.; BOISSIER, J.; FREITAG, M.; PORTELA, J.; CLIMENT, D.; PERRIN, C.; ZERLOTINI, A.; GRUNAU, C. Background: In the leuphotrochozoan parasitic platyhelminth Schistosoma mansoni, male individuals are homogametic (ZZ) whereas females are heterogametic (ZW). To elucidate the mechanisms that led to t... ... Repository: BDPA Publication year: 2012
