What is rose rosette virus?
Rose rosette disease, also known as witches’-broom of rose, is caused by a virus (Emaravirus sp.) that is spread by a very small, eriophyid mite. The disease is limited to plants in the genus Rosa but R. … Its main host is the multiflora rose, which is considered a noxious weed throughout much of the United States.

TMV is very easily transmitted when an infected leaf rubs against a leaf of a healthy plant, by contaminated tools, and occasionally by workers whose hands become contaminated with TMV after smoking cigarettes.

Does cucumber mosaic virus live in soil?
Great for the aphid, but really unfortunate for the hundreds of plants it can bite during those few hours. If there’s any good news here it’s that unlike some other mosaics, Cucumber Mosaic Virus can’t be passed along through seeds and won’t persist in plant debris or soil.
What is called Phyllotaxy?
In botany, phyllotaxis or phyllotaxy is the arrangement of leaves on a plant stem (from Ancient Greek phýllon “leaf” and táxis “arrangement”). Phyllotactic spirals form a distinctive class of patterns in nature. The term was coined by Charles Bonnet to describe the arrangement of leaves on a plant.
