Molecular Genetic Typing of Staphylococcus aureus from Cows, Goats, Sheep, Rabbits and Chickens [PDF]

open access: yes, 2006
End of project reportsS. aureus can also cause a number of infections in animals such as tick-associated pyaemia in lambs, staphylococcosis in rabbits, septicaemia, abscesses and chondronecrosis in chickens and pneumonia and osteomyelitis complex in ...

Chromosomal anchoring of linkage groups and identification of wing size QTL using markers and FISH probes derived from microdissected chromosomes in Nasonia(Pteromalidae : Hymenoptera) [PDF]

open access: yes, 2004
Nasonia vitripennis is a small parasitic hymenopteran with a 50-year history of genetic work including linkage mapping with mutant and molecular markers. For the first time we are now able to anchor linkage groups to specific chromosomes.

Assessment of Genetic Diversity in Cultivated Tomato (Solanum Lycopersicum L.) Genotypes Using Rapd Primers

open access: yesJournal of Horticultural Research, 2013
Random Amplified Polymorphic DNA (RAPD) analysis was carried out on 19 Azerbaijan tomato genotypes, both cultivars and local populations. A total of 26 amplified products were revealed by 6 primers. The genetic similarity among evaluated genotypes ranged

Landscape influence on pollinator population genetic connectivity

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 285-302, May 2025.
We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...

Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]

open access: yes, 2001
Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

Karyological and molecular studies between six species of Plantago in the Northern border region at Saudi Arabia

open access: yesJournal of Taibah University for Science, 2019
Karyotype characters, mitotic metaphase chromosomes, and haploid ideograms of six species of Plantago L. species. Analysis of somatic metaphases showed that the chromosome numbers of these species were 2n = 8 for P. ovata, 2n = 10 for P.

Analysis of the genetic diversity of Hepatacodium miconioides at different altitude in Tiantai mountain in Zhejiang Province and its relationship with environmental factors(浙江天台山不同海拔高度七子花种群遗传多样性及其与环境因子的相关性分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2005
采用RAPD技术对浙江天台山3个海拔高度的七子花(Heptatcodium miconioides)天然种群的遗传多样性、遗传分化以及与环境因子的相关性进行了研究.12种随机引物在60株个体中共检测到122个可重复的位点.3个种群多态位点百分率为18.85% ~23.77%,平均为21.86%,表明各种群的遗传多样性水平比较低.3个种群Shannon和Nei指数平均为0.132 9、0.092 5,其值较低.虽然3个种群所分布的地理范围小,但种群间存在明显的遗传分化 ...

Molecular Genetic Diversity Study of Forest Coffee Tree (Coffea arabica L.) Populations in Ethiopia: Implications for Conservation and Breeding [PDF]

open access: yes, 2005
Coffee provides one of the most widely drunk beverages in the world, and is a very important source of foreign exchange income for many countries. Coffea arabica, which contributes over 70 percent of the world's coffee productions, is characterized by a ...

Development of a locus-specific, co-dominant SCAR marker for assisted-selection of the Sw-5 (Tospovirus resistance) gene cluster in a wide range of tomato accessions [PDF]

open access: yes, 2010
The best levels of broad-spectrum Tospovirus resistance reported in tomatoes thus far are conferred by the Sw-5 locus. This locus contains at least five paralogues (denoted Sw-5a through Sw-5e), of which Sw-5b represents the actual resistance gene.
