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]
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.
Ipomoea indica flowers change from bright blue to a faded purple by the end of the day. [2] Hibiscus mutabilis flowers changing colors during a day. Floral color change occurs in flowers in a wide range of angiosperm taxa that undergo a color change associated with their age, or after successful pollination. [3] [4]
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
Variegated plants have long been valued by gardeners, as the usually lighter-coloured variegation can 'lift' what would otherwise be blocks of solid green foliage. Many gardening societies have specialist variegated plants groups, such as the Hardy Plant Society's Variegated Plant Special Interest Group in the UK.
It causes Blue Mold of apples, one of the most prevalent and economically damaging post-harvest diseases of apples. Though primarily known as a disease of apples, this plant pathogen can infect a wide range of hosts, including pears, strawberries, tomatoes, corn, and rice.
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]
