Continental-scale patterns of pathogen prevalence: a case study on the corncrake [PDF]

open access: yes, 2014
Pathogen infections can represent a substantial threat to wild populations, especially those already limited in size. To determine how much variation in the pathogens observed among fragmented populations is caused by ecological factors, one needs to ...

Use of Prolamin Polymorphism to Describe Genetic Variation in a Collection of Barley Genetic Resources

open access: yesCzech Journal of Genetics and Plant Breeding, 2003
The polymorphism of prolamin storage proteins was studied in seed samples of 20 historical cultivars of spring barley (Hordeum vulgare L.) of Czech and Slovak origin, using polyacrylamide gel electrophoresis (PAGE). Only two samples were uniform.

Genetic Variation of Dacrycarpus Imbricatus in Bromo Tengger Semeru National Park, East Java Based on TrnL (UAA) Intron Region [PDF]

open access: yes, 2013
The conservation of Jamuju Dacrycarpus imbricatus (Blume) de Laub. in Java Island has been considered important. One of the the limitation of such program is related to the viability data on the genetic diversity of species target.

Genetic and Morphological Variation Among Populations of Duckweed Species in Thailand

open access: yesPlants
Duckweeds have emerged as frontier plants in research, food, and bioenergy applications. Consistency in genetic and morphological traits within species is therefore crucial for their effective use.

Genetic variation stimulated by epigenetic modification. [PDF]

open access: yesPLoS ONE, 2008
Homologous recombination is essential for maintaining genomic integrity. A common repair mechanism, it uses a homologous or homeologous donor as a template for repair of a damaged target gene.

Cellular deconvolution of GTEx tissues powers discovery of disease and cell-type associated regulatory variants. [PDF]

open access: yes, 2020
The Genotype-Tissue Expression (GTEx) resource has provided insights into the regulatory impact of genetic variation on gene expression across human tissues; however, thus far has not considered how variation acts at the resolution of the different cell ...

Multiple FLC haplotypes defined by independent cis-regulatory variation underpin life history diversity in Arabidopsis thaliana [PDF]

open access: yes, 2014
Relating molecular variation to phenotypic diversity is a central goal in evolutionary biology. In Arabidopsis thaliana, FLOWERING LOCUS C (FLC) is a major determinant of variation in vernalization—the acceleration of flowering by prolonged cold.

VARIASI GENETIK LOCI STR CODIS (THO1,TPOX) MANUSIA GILIMANUK (PULAU BALI)

open access: yesBerkala Arkeologi, 2013
It is assumed that Mongoloid’s migration came from western and northern part of Indonesia in various waves of migration. The migrant population then mixed with initial inhabitants, which are Australomelanesoid.
