Bacterial wilt of carnations is a bacterial disease caused by the plant pathogen Paraburkholderia caryophylli (often referred to as Burkholderia caryophylli). [1] Previously named Pseudomonas caryophilli, [ 2 ] the pathogen is an aerobic gram negative bacteria known for only being capable of entering its host through wounds.
Its exact natural range is uncertain due to extensive cultivation over the last 2,000 years. Carnations are prized for their vibrant colors, delicate fringed petals, and fragrance. The scent of carnations is often described as spicy, clove-like, or reminiscent of a combination of cinnamon and nutmeg, hence the common name "clove pink".
The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
In general, carotenoids absorb wavelengths ranging from 400 to 550 nanometers (violet to green light). This causes the compounds to be deeply colored yellow, orange, or red. Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species, [3] but many plant colors, especially reds and purples, are due to polyphenols.

A carcinogen (/ k ɑːr ˈ s ɪ n ə dʒ ən /) is any agent that promotes the development of cancer. [1] Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and biologic agents such as viruses and bacteria. [2]
Residents of the rural West Virginia town at the heart of "Dark Waters" may (or may not) have been an extreme case, but their decades-long consumption of contaminated water was found to be the ...
