Lonicera Infectious Variegation
Maize White Line Mosaic
Vein yellowing and variegation on honeysuckle;
graft-transmitted.
On field corn and weed hosts including
Panicum,
Setaria
and
Digitaria
.
Maize Dwarf Mosaic Potyvirus
Malva Vein Clearing Potyvirus
First noted in Ohio in 1962 and since devastating
to corn in many states. Red to purple streaks in
upper leaves, ears usually incomplete; plants
dwarfed with great reduction in yield. Transmis-
sion by corn leaf and peach aphids. Occurs also
on
Sorghum
sp. and
Triticum
sp.
Caused vein clearing and yellow mosaics on
many
Malva
and
Lavatera
species. Virus is
known as Malva Mosaic, Malva Green Mosaic
or Malva Yellow Vein Mosaic Virus.
Melon Leaf Curl Bigeminivirus
Maize Chlorotic Mottle Machlovirus
Caused leaf mottling and chlorosis on Cucurbits.
Usually occurred together with many potyviruses
on infected maize plants showing severe systemic
necrosis and stunting. Plant often dying.
Melon Necrotic Spot Carmovirus
Transmitted by fungus
Olpidium radical
,by
sap, by contact between plants and by seeds.
It caused chlorotic and necrotic spots on
Cucurbits.
Maize Rayado Fino Marafivirus
Initially described as a strain of Corn Stunt Virus
now in the type species of Marafivirus. Virus
frequently occurred in mixed infection with
Phytoplasmas. It is multiplied in the vector,
Dalbulus maydis
, Cocadellidae and is not trans-
mitted by sap, grafting or seeds.
Mimosa Striped Chlorosis Badnavirus
Infected
Albizzia
sp. plant showed
chlorotic stripes along leaf vein and interveinal
chlorosis.
Maize Stripe Tenuivirus
Mint Crinkle Closterovirus
Caused yellow striping and chlorosis on
natural hosts.
Zea mays, Sorghum vulgare,
S. bicolor, Triticum aestivum
and
Hordeum
vulgare
.
On golden ginger mint.
Mirabilis Mosaic Caulimovirus
Maize Stunt
¼
Maize Chlorotic Dwarf
Waikavirus
Genome consists of DNA, virus-transmitted in
semi-persistent manner by aphid,
Myzus persicae
and by sap.
Corn Stunt.
