Chromosome stickiness impairs meiosis and influences reproductive success in Panicum maximum (Poaceae) hybrid plants

C. Pessim, Pagliarini, M. S., Silva, N., and Jank, L., Chromosome stickiness impairs meiosis and influences reproductive success in Panicum maximum (Poaceae) hybrid plants, vol. 14, pp. 4195-4202, 2015.

Chromosome stickiness has been studied in several species of higher plants and is characterized by sticky clumps of chromatin resulting in sterility. Chromosome stickiness was recorded in Panicum maximum hybrid plants that were cultivated in the field. In the meiocytes affected, chromosomes clumped into amorphous masses that did not orient themselves on the equatorial plate, and anaphase I disjunction failed to occur. After a normal cytokinesis, the masses of chromatin were divided between both daughter cells.

Body color development and genetic analysis of hybrid transparent crucian carp (Carassius auratus)

W. Xu, Tong, G. X., Geng, L. W., and Jiang, H. F., Body color development and genetic analysis of hybrid transparent crucian carp (Carassius auratus), vol. 14, pp. 4399-4407, 2015.

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern at approximately 54 days post-hatching.

Analysis of DNA methylation patterns and levels in maize hybrids and their parents

T. J. Liu, Sun, L. F., Shan, X. H., Wu, Y., Su, S. Z., Li, S. P., Liu, H. K., Han, J. Y., and Yuan, Y. P., Analysis of DNA methylation patterns and levels in maize hybrids and their parents, vol. 13, pp. 8458-8468, 2014.

Heterosis is the superior performance of heterozygous individuals and has been widely exploited in plant breeding, although the underlying regulatory mechanisms still remain largely elusive. To understand the molecular basis of heterosis in maize, in this study, roots and leaves at the seedling stage and embryos and endosperm tissues 15 days after fertilization of 2 elite hybrids and their parental lines were used to estimate the levels and patterns of cytosine methylation by the methylation-sensitive amplification polymorphism method.

Microsatellite analysis as a tool for discriminating an interfamily hybrid between olive flounder and starry flounder

J. - H. Kang, Kim, Y. - K., Park, J. - Y., An, C. - M., Nam, M. - M., Byun, S. G., Lee, B. I., Lee, J. H., and Choi, T. - J., Microsatellite analysis as a tool for discriminating an interfamily hybrid between olive flounder and starry flounder, vol. 10, pp. 2786-2794, 2011.

An interspecific artificial hybrid was produced between two economically important aquaculture flatfish: olive flounder (Paralichthys olivaceus) and starry flounder (P. stellatus). This hybrid displays the rapid growth characteristic of the former and tolerance to low temperatures and low salinity of the latter, but the genetics of inheritance in this hybrid have not been elucidated. Polymorphic microsatellite markers developed for P. olivaceus and P.

Evidence for a natural hybrid of peacock bass (Cichlamonoculus vs Cichla temensis) based on esterase electrophoretic patterns

A. Saturnino Teixeira and de Oliveira, Sda Silva, Evidence for a natural hybrid of peacock bass (Cichlamonoculus vs Cichla temensis) based on esterase electrophoretic patterns, vol. 4, pp. 74-83, 2005.

Esterase (Est) and esterase-D (Est-D) electrophoretic patterns identified by starch gel electrophoresis of skeletal muscle protein extracts of 184 specimens of three species of peacock bass, locally known as tucunarés (Cichla monoculus, C. temensis and Cichla sp), plus four specimens of a supposed hybrid (C. monoculus vs C. temensis), collected from the Central Amazon, were examined to determine if they could aid in identifying a supposed hybrid between C. monoculus and C. temensis.
