Zeocin is a trade name for a formulation of phleomycin D1, a glycopeptide antibiotic and one of the phleomycins from Streptomyces verticillus belonging to the bleomycin family of antibiotics. [1] It is a broad-spectrum antibiotic that is effective against most aerobic organisms including bacteria, filamentous fungi, yeast, plant, and animal cells.
In plant immunology, the hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
Adult plant resistance (APR) is a specialist term referring to quantitative resistance that is not effective in the seedling stage but is effective throughout many remaining plant growth stages. [ 43 ] [ 44 ] [ 42 ] The difference between adult plant resistance and seedling resistance is especially important in annual crops . [ 45 ]
The quality of G418 is not based on just the potency, but more on the selectivity defined by the killing curve of the sensitive cells vs the resistant cells. A good G418 product has the lowest LD 50 for sensitive cells (such as NIH 3T3) and the highest LD 50 (can be up to 5,000 μg/ml) for resistant cells (NIH 3T3 transfected with resistant ...
Over the past decade, the study of induced system resistance has become a very active field of research. [12] Methods to artificially activate the ISR pathway is an active area of research. [13] The research and application of inducing plant system resistance have been encouraging but are not yet a major factor in controlling plant pathogens.
Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen. SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution. [ 1 ]
One is a plant gene called the resistance gene. The other is a parasite gene called the avirulence (Avr) gene. Plants producing a specific R gene product are resistant towards a pathogen that produces the corresponding Avr gene product. [5] Gene-for-gene relationships are a widespread and very important aspect of plant disease resistance.
Plant disease resistance is the ability of a plant to prevent and terminate infections from plant pathogens. Structures that help plants prevent pathogens from entering are the cuticular layer, cell walls, and stomata guard cells.
