Does cancer affect plants?
Please be more specific. If you mean, can plants catch cancer from animals, the
answer is no. Plants do not catch animal diseases. As a matter of fact, animals, including people, do not catch cancer from each other, unless it is caused by a retrovirus, & even then, contagion is extremely rare. If you mean, do plants get cancer, in general, there are no diseases I know of in plants where cell division runs amok and spreads throughout the plant. Occasionally, a plant will exhibit some excessive callous proliferation at the site of a specific wound, but I never heard of it spreading to another part of the plant. Sometimes plants get galls caused by a disease or insect, but it is not really the same as cancer. There is a condition in plants called fasciation, where the growing point becomes a line, or monstrose growth, where the growing point becomes totally confused. The resulting plant is a curiosity, but it is not a sickness & does not affect the plant's health.

If you mean, do plants get cancer,
Yes. I meant to ask if plants can get cancer on their own. Just like humans and animals. Virus infection? In theory, any cell [plant, animal, fungi, algae etc.] constantly irritated by viral enzymes could undergoes some mutation. Right? BTW, I have notice some abnormally bright green spots in my tulip petals. They are supposed to be yellow, not green. Could this be due to viral infection of chloroplasts in cells of the "blood green" region's of the tulip's petals? |

They are supposed to be yellow, not green. I would have to see them to hazard a guess. it does not sound like a virus. In tulips, a virus may cause streaks in the flowers, or no other symptom besides general decline. A virus infection in a plant is rarely localized that I know of. Sooner or later it spreads to the entire plant. Iris, Central NY, Zone 5a, Sunset Zone 40 "If we see light at the end of the tunnel, It's the light of the oncoming train." Robert Lowell (1917-1977) |

In theory, any cell [plant, animal, fungi, algae etc.] constantly irritated by viral enzymes could undergoes some mutation. Right? Look up Agrobacterium tumifaciens (I probably spelled that wrong). It causes plant tumors, and the tumor producing genes get incorporated into the chromosomes of the host. There are a number of other organisms that cause plants to produce "tumors", including some insects that induce galls. Fungi and nematodes induce lumpos on roots in "root knot" disease, and notrogen fixing bacteria induce similar root nodules. Often it's done by secreting plant hormones. It's hard to decide what a cancer would be like in a plant. Plants don't have fixed forms like most animals do, and they normally have embryonic cells all the time. They also lack a circulatory system that can transport cells. BTW, I have notice some abnormally bright green spots in my tulip petals. They are supposed to be yellow, not green. Could this be due to viral infection of chloroplasts in cells of the "blood green" region's of the tulip's petals? It could be. Or it could be from fungal or insect damage. The petals are green to start with, and local damage might prevent a patch of tissue from maturing properly. There's a group of tulip cultivars called viridifloras that retain green color in parts of the petals as a genetic trait. You sound like an observant person with an inquiring mind. There are all kinds of interesting things to be observed with plants. Every year or two I find an orange in the store with a somatic mutation that makes the skin much thinner or thicker over a quarter section of the surface. I once found an onion plant among the normal ones that had longitudinal yellow stripes on the leaves. This was probably due to the kind of viral infection you are thinking of (the yellow stripes, not the green ones). I wanted to see if it might be genetic instead, but the plant was quite weak and didn't survive to set seed. |
