You asked: What is Mosaic in plants?

What is leaf mosaic?

A leaf mosaic can be defined as an arrangement of the leaves of a single plant which tends to decrease the shading of one leaf by another and to fill the space available for light interception.

What is leaf mosaic pattern?

1 : the arrangement of foliage in most plants (as in the common ivy) in such a pattern as to expose the maximum number of leaves to the direct rays of the sun with little loss of intervening space.

How do you know if a plant is Mosaic?

Mosaic symptoms are variable but commonly include irregular leaf mottling (light and dark green or yellow patches or streaks). Leaves are commonly stunted, curled, or puckered; veins may be lighter than normal or banded with dark green or yellow.

Is mosaic virus harmful to humans?

Accordingly, they are not considered harmful for humans. However, a few studies questioned the certainty of this paradigm. Tobacco mosaic virus (TMV) RNA has been detected in human samples and TMV RNA translation has been described in animal cells.

Does mosaic virus stay in soil?

Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.

Which disease is caused for mosaic disease?

This disease is caused by a complex consisting of the monopartite begomovirus Bhendi yellow vein mosaic virus (BYVMV, family: Geminiviridae) and a small satellite DNA beta component. BYVMV can systemically infect bhendi upon agroinoculation but produces only mild leaf curling in this host.

What is leaf rolling?

Leaf rolling is an effective protective mechanism from the effects of high light levels in agricultural fields and protects leaves of unirrigated plants from photodamage. The rolling reduces effective leaf area and transpiration, and thus is a potentially useful drought avoidance mechanism in dry areas.

Can plant viruses be cured?

Management of Plant Virus Diseases

Although there are virtually no antiviral compounds available to cure plants with viral diseases, efficient control measures can greatly mitigate or prevent disease from occurring. Virus identification is a mandatory first step in the management of a disease caused by a virus.
