Programas de melhoramento florestal são dispendiosos e de longa duração. A falta de semente melhorada, adequada aos requisitos para produção e industrialização de madeira sólida e de resina de pínus motivou a organização de empresas desses segmen- tos em um sistema cooperativo para implementar um projeto com enfoque na conser- vação e melhoramento genético. A base genética já conta com mais de 200 matrizes selecionadas para produção de madeira e mais 2.500 em pré-avaliação para produção de resina. As matrizes selecionadas comporão o banco genético para os cruzamentos controlados. |

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 catfishes in South Asian countries, but little is known about their SD system. Here, we generated novel genomic resources for 12 Pangasiids and characterized their SD system. Based on a Pangasianodon hypophthalmus chromosome-scale genome assembly, we identified an anti-Müllerian hormone receptor type II gene (amhr2) duplication, which was further characterized as being sex-linked in males and expressed only in testes. These results point to a Y chromosome male-specific duplication (amhr2by) of the autosomal amhr2a. Sequence annotation revealed that the P. hypophthalmus Amhr2by is truncated in its N-terminal domain, lacking the cysteine-rich extracellular part of the receptor that is crucial for ligand binding, suggesting a potential route for its neofunctionalization. Reference-guided assembly of 11 additional Pangasiids, along with sex-linkage studies, revealed that this truncated amhr2by duplication is a male-specific conserved gene in Pangasiids. Reconstructions of the amhr2 phylogeny suggested that amhr2by arose from an ancient duplication/insertion event at the root of the Siluroidei radiation that is dated to ~100 million years ago. Together these results bring multiple lines of evidence supporting that amhr2by is an ancient and conserved master sex-determining gene in Pangasiids, a finding that high-lights the recurrent use of the transforming growth factor ? pathway, which is often used for the recruitment of teleost master SD genes, and provides another empirical case towards firther understanding of dynamics of SD systems.
