the sugarcane mosaic virus (SCMV).
(A)Mosaic on young leaves of corn
plant. (B) Mosaic, yellowing-
reddening and stunting of corn plant.

SCMV-infected plant. (D) Electron

3. Researchers in Boyce
Thompson Institute for Plant
Research and partners reported
the use of sugarcane mosaic
virus (SCMV) vector for rapid
screening of proteins that block
the growth of insect herbivores.
The results are published in
the Plant Biotechnology
Journal.
5. Symptoms:
• Blotchy or streaky patterns of yellow and green color.
• Grasses showing mosaic symptoms tend to have broken yellow
streaks running between veins on an otherwise green blade.
• There are many irregular yellow and green inlays, stripes, or
mottles alternate with parallel veins on symptomatic leaves,
more clearly visible against the sunlight.
• The tips of new leaves are abnormally twisted.
6. Host
All three viruses infect sugarcane:
sorghum (Sorghum bicolor L. )
corn (Zea mays L.)
panicum (Panicum miliaceum L.)
millet (Setaria italica L.)
green bristlegrass (Setaria viridis L.)
Johnson grass (Sorghum halepense L.)
Sudan grass [Sorghum sudanense)
Gramineae family.

disease

leaves. (a). healthy leaves; (b). infected leaves; (c).
severely infected leaves; (d). abnormally twisted top
leaves of infected plant.
9. Multitrophic interactions
in sugarcane. In the
Virus-Aphid Complex,
viral pathogens such as
sugarcane mosaic virus
(SCMV) and yellow leaf
virus (ScYLV) are
transmitted through
different molecular
strategies by aphids
feeding on sugarcane
leaves.
