Cytological Identification of Chromosomal Rearrangements in Doritaenopsis and Phalaenopsis
(Journal of International Cooperation (Taiwan) 2(1): 1-11, 2007-09-01)
This study investigated the impact of gross chromosomal rearrangements, specifically translocations and inversions, on the division of pollen mother cells in hybrids Dtps. Queen Beer, Dtps. Sinica Sunday, Dtps. Sweet ...
Meiotic Chromosome Behavior and Capsule Setting in Doritaenopsis Hybrids
(J. AMER. SOC. HORT. SCI. 133(1):107–116. 2008, 2008-10-06)
The development of new cultivars in Doritaenopsis Guillaum. & Lami orchids is often hindered by factors such as low seed count in hybrids. Cytological study may offer the ability to develop new hybrids by revealing cultivars ...
A time- and cost-effective strategy to sequence mammalian Y Chromosomes: an application to the de novo assembly of gorilla Y
(2016-02)
The mammalian Y Chromosome sequence, critical for studying male fertility and dispersal, is enriched in repeats and palindromes, and thus, is the most difficult component of the genome to assemble. Previously, expensive ...
Karyotype of the yellow-bellied sea snake, Pelamis platurus
(1980)
In this paper we describe the karyotype of the yellow-bellied sea snake, Pelamis platurus from Costa Rica. The diploid number is 38 chromosomes, with 20 macrochromosomes and 18 microchromosomes. The pairs 1 and 2 are ...
Protocol for the preparation of Arabiopsis meiotic chromosome spreads and fluorescent in situ hybridization
(Bio-protocol 4(7), e1102, 2014, 2014-04-05)
This protocol is a more detailed version of previous protocols (Yang et al., 2011; Bolaños-Villegas et al., 2013) developed for the examination of meiotic chromosome spreads. Meiotic chromosome spreads are useful to determine ...
Reduced activity of Arabidopsis chromosome-cohesion regulator gene CTF7/ECO1 alters cytosine methylation status and retrotransposon expression
(2015-05-01)
Multicellular organisms such as higher plants require timely regulation of DNA replication and cell division to grow and develop. Recent work in Arabidopsis has shown that chromosome segregation during meiosis and mitosis ...
X-chromosome methylation in manifesting and healthy carriers of dystrophinopathies: concordance of activation ratios among first degree female relatives and skewed inactivation as cause of the affected phenotypes
(1995)
The X-chromosome activity states of 11 manifesting carriers of dystrophinopathies, all with normal karyotypes, were estimated by restriction fragment length polymorphism (RFLP)-methylation analysis with the probes M27I3 ...
Acrylamide: dermal exposure produces genetic damage in male mouse germ cells
(1992)
Acrylamide Is used extensively in sewage and wastewater treatment plants, in the paper and pulp industry, in treatment of potable water, and in research laboratories for chromatography,
eltetrophoresis. and electron ...
Genetic variation of the Y chromosome in Chibcha-Speaking amerindians of Costa Rica and Panama
(Human Biology 77(1): 71-91, 2005)
Genetic variation of the Y chromosome in five Chibchan tribes (Bribri, Cabecar, Guaymi, Huetar, and Teribe) of Costa Rica and Panama was analyzed using six microsatellite loci (DYS 19, DYS389A, DYS389B, DYS390, DYS391, and ...
Chromosomal defects in 34 male homosexuals, half of them with HIV antibodies
(Revista de Biologíaa Tropical 50(1):347-353, 2002, 2002-09)
Most of the research about viral interactions with human chromosomes was done during the sixties
and early seventies and very few was performed after the human immunodeficiency virus (HIV) appearance as
an epidemic in ...
