Authors: S.R. N�³brega, A.L.F. Coelho, C.F. Verola, I.R. Costa, R. Vila�§a, F.J.F. Luz and W.F. Ara�ºjo
Studies addressing chromosome variations have elucidated many points regarding the taxonomy of the Orchidaceae. Epidendrum L. besides being one the largest orchid genera, present remarkable morphological, and inter- and intraspecific chromosome variations. Thus, based on a previous report on flower color variation in individua.. Read More»

Microsatellite in Aeschynomene falcata (Leguminosae): diversity, cross-amplification, and chromosome localization
Authors: C.A. Polido1,3, C.C. Mantello2, A.P. Moraes1,4, A.P. Souza1,2 and E.R. Forni-Martins1
Aeschynomene falcata is an important forage species; however, because of low seed production, it is underutilized as forage species. Aeschynomene is a polyphyletic genus with a challenging taxonomic position. Two subgenera have been proposed, and it is suggested that Aeschynomene can be split in 2 genera... Read More»

Cloning and expression analysis of the 37-kDa laminin receptor precursor gene from Hyriopsis cumingii
Authors: X.Z. Chang1, J.L. Li1,2, Z.Y. Bai1 and X.L. Li1
Hyriopsis cumingii is an economically important freshwater pearl mussel with high pearl quality that is endemic in China. Investigation of genes relevant to shell formation is important for increased pearl output. The substances that form mollusk shells are secreted by epithelial cells in the mantle, the proliferation of which influences secretion ability.. Read More»

DNA elimination in embryogenic development of Pennisetum glaucum x Pennisetum purpureum (Poaceae) hybrids
Authors: J.D. Nunes1, A.L.S. Azevedo1, A.V. Pereira1, C.M.P. Paula2, J.M.S. Campos3, F.J.S. L�©do1 and V.B. Santos4
Interspecific hybridization between Napier grass (Pennisetum purpureum), which is widely grown in Brazil for cattle forage, and pearl millet (Pennisetum glaucum) has been used as a breeding strategy for the development of improved cultivars. However, the hybrid between these two species is sterile due to its triploid condition (2n = 3x = 21 chromosomes), .. Read More»

Microsporogenesis in Paspalum conspersum Schrad. (Virgata group) with different ploidy levels
Authors: L. Janke1, F.H.D. Souza2, J.F.M. Valls3 and M.S. Pagliarini1
Knowledge about the cytology and reproductive behavior of a species is indispensable for hybridization programs. This is especially true for species belonging to the genus Paspalum, among which apomixis and a wide range of ploidy levels are frequently found. Paspalum conspersum Schrad. is a robust and warm-season perennial bunchgrass native to South Ameri.. Read More»

Changes of gene expression profiles across different phases of vascular calcification in rats
Authors: Z.M. Jiang, X.J. Wu, Y. Liu, X.H. Du, S.J. Shen, L.Y. Xu,W.X. Sun
This study investigated the alteration of gene expression profiles in order to gain a deeper understanding into the molecular mechanism involved in different processes of vascular calcification (VC). Sprague Dawley (SD) rats were injected with 300,000 μg/kg vitamin D3 and gavaged with 25 mg/kg nicotine for 8 or 16 weeks to .. Read More»

Different timing and spatial separation of parental chromosomes in intergeneric somatic hybrids between Brassica napus and Orychophragmus violaceus
Authors: L. Ding, Z.G. Zhao, X.H. Ge and Z.Y. Li
Experimental and newly formed hybrids and polyploids generated by wide crosses usually show varying degrees of cytological instability. The spatial separation of parental genomes and uniparental chromosome elimination in hybrid cells has been reported in many hybrids from plants and animals. Herein, the behavior of parental ge..

Molecular cytogenetic identification of a wheat (Triticum aestivum)-American dune grass (Leymus mollis) translocation line resistant to stripe rust
Authors: Y. Bao, J. Wang, F. He, H. Ma and H. Wang
Leymus mollis, a perennial allotetraploid (2n = 4x = 28), known as American dune grass, is a wild relative of wheat that could be useful for cultivar improvement. Shannong0096, developed from interspecific hybridization between common wheat cv. Yannong15 and L. mollis, was analyzed with cytological procedures, genomic in situ .. Read More»
