The disorder can cause heart abnormalities and seizures if the amount of methemoglobin in the blood exceeds 20 percent, but at levels between 10 and 20 percent it can cause blue skin without other symptoms. Most of the Fugates lived long and healthy lives. The "bluest" of the blue Fugates, Luna Stacy, had 13 children and lived to age 84. [6]
Blue stain fungi (also known as sap stain fungi) is a vague term including various fungi that cause dark staining in sapwood. [1] The staining is most often blue, but could also be grey or black. Because the grouping is based solely on symptomatics, it is not a monophyletic grouping.
The fungus can also cause cavities in wood and plants via an erosion-type attack. [23] The ability of the fungus to degrade the wood of Populus tremuloides (trembling aspen) has been noted to limit the sale of aspen, which represents 54% of commercial timber. [24] P. fastigiata also commonly causes blue staining
Grosmannia clavigera is a species of sac fungus that causes blue stain in wood. It spreads to lodgepole pine, ponderosa pine, Douglas-fir, and whitebark pine trees from the body and a special structure in the heads of mountain pine beetles.
Penicillium spp. commonly grow on plant and animal debris on soil, and in senescing plant tissues. [6] In garlic, it is thought that the pathogen survives in infected cloves rather than the soil. [6] Initial infection usually occurs through wounded plant tissue caused by bruising, sun-scald, freezing injury or mechanical damage to the plant. [6]
The Fugates, a family that lived in the hills of Kentucky in the US, had the hereditary form. They are known as the "Blue Fugates". [ 30 ] Martin Fugate and Elizabeth Smith, who had married and settled near Hazard, Kentucky , around 1800, were both carriers of the recessive methemoglobinemia (met-H) gene, as was a nearby clan with whom the ...
It is known that acidification of soil can cause change of the hydrangea flower colour from red/pink to blue/violet. Explanation of this phenomenon we can find in the molar ratio of co-pigment (acylquninic acid) to anthocyanin, which is much higher in the blue cells, also the level of Al3+ ions is higher in the blue flowers.
Penicillium expansum can be identified by its morphological characteristics and secondary metabolites in fruit or in axenic culture. [8] The presence of the secondary metabolite patulin can suggest P. expansum infection, but this method is not species-specific as a number of different Penicillium species and their allies produce patulin.
