A P1-derived artificial chromosome, or PAC, is a DNA construct derived from the DNA of P1 bacteriophages and Bacterial artificial chromosome.It can carry large amounts (about 100–300 kilobases) of other sequences for a variety of bioengineering purposes in bacteria.
The rice plants in the strain can be bred to other rice strains or cultivars, and if desirable plants are produced, these are further bred to stabilize the desirable traits; the stabilized plants that can be propagated and "come true" (remain identical to the parent plant) are given a cultivar name and released into production to be used by ...
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
F. oxysporum strains are ubiquitous soil inhabitants that have the ability to exist as saprophytes, and degrade lignin [11] [12] and complex carbohydrates [13] [14] [1] associated with soil debris. They are pervasive plant endophytes that can colonize plant roots [ 15 ] [ 16 ] and may even protect plants or form the basis of disease suppression.
The genetic makeup of a soybean gives it a wide variety of uses, thus keeping it in high demand. First, manufacturers only wanted to use transgenics to be able to grow more soybeans at a minimal cost to meet this demand, and to fix any problems in the growing process, but they eventually found they could modify the soybean to contain healthier components, or even focus on one aspect of the ...
Two strains of the bacterium are associated with the farmer. One strain serves as a food source and the other strain serves as a symbioant that produces beneficial secondary metabolites. The main genetic difference between these two strains is a mutation of the global activator gene called gacA. This gene plays a key role in gene regulation ...
The bacterium can't penetrate the host plant without an entry point such as a wound. Factors leading to wounds in plants include cultural practices, grafting, freezing injury, growth cracks, soil insects, and other animals in the environment causing damage to the plant.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible. To change this template's initial visibility, the |state= parameter may be used:
