Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Plant genetics is similar in many ways to animal genetics but ...
Autosomal genetic studies have confirmed that Basques share close genetic ties to other Europeans, especially with Spaniards, who have a common genetic identity of over 70 % with Basques, a homogeneity amongst both their Spanish and French populations, according to high-density SNP genotyping study done in May 2010, and a genomic ...
There are a number of Basque breeds and cultivars. These are domesticated animals that have been bred - or plant species cultivated - for particular traits and features by Basque people in the Basque Country. Some, such as the Alano Español, are not originally Basque but have only survived in the Basque Country.
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
The first use of plant genetic resources dates to more than 10,000 years ago, when farmers selected from the genetic variation they found in wild plants to develop their crops. As human populations moved to different climates and ecosystems, taking the crops with them, the crops adapted to the new environments, developing, for example, genetic ...
In the absence of sexual reproduction, the genetic composition of plant material being multiplied remains essentially the same as its source plant. Clones of mother plants can be made with the exact genetic composition of the mother plant. Superior plants are selected and propagated vegetatively; the vegetative propagated offspring are used to ...
Plants display the most obvious examples of ecophenotypic variation. One example are trees growing in the woods developing long straight trunks, with branching crowns high in the canopy, while the same species growing alone in the open develops a spreading form, branching much lower to the ground.
The arrangement of leaves on the plant body is such that the plant can maximally harvest light under the given constraints, and hence, one might expect the trait to be genetically robust. However, it may not be so. In maize, a mutation in only one gene called abphyl (abnormal phyllotaxy) was enough to change the phyllotaxy of the leaves.
