Host of Isolate and Habitat Details
Source of
isolate: Beta vulgaris, Lactuca sativa, Spinacia oleracea.
Natural host and symptoms
Beta vulgaris, Lactuca sativa, Spinacia
oleracea in mixed infections, the virus enhances the symptoms induced
by beet western yellows virus; the outer leaves of infected plants, especially
those of lettuce, develop numerous angular chlorotic spots to produce the
so-called speckles disease. Symptoms of the complex become less conspicuous as
ambient temperatures rise. Comments on host and host range: the host range of
the virus is wider when viruliferous aphids are used to infect plants.

ICTVdB Virus Code: 00.078.0.01.006. Virus accession number: 78001006. Obsolete virus code: 78.0.1.0.005; superceded accession number: 78010005.
ICTV approved acronym: LSMV. Virus is an ICTV approved species. Virus is of the genus 00.078.0.01. Umbravirus; not assigned to a family.
Domain
Viral hosts belong to the Domain
Eucarya.
Domain Eucarya
Kingdom Plantae.
Kingdom Plantae
Phylum Magnoliophyta
(Angiosperms, Class Magnoliopsida (Dicotyledonae).
Class Magnoliopsida (Dicotyledonae)
Subclass
ASTERIDAE; Order Asterales.
General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include chlorosis and development of patterns or markings that are visible in the intercostal regions. Intercostal regions show chlorosis. Leaves with mottle and flecking have blotchy mottle.
Vector Transmission:
Virus is transmitted by arthropods, by insects
of the order Hemiptera, family Aphididae; Acyrthosiphon (Aulacorthum) solani,
Brevicoryne brassicae, Myzus persicae. The principal natural vector(s) are
Myzus persicae. Virus is transmitted in a persistent manner; requires,
for vector transmission, a helper virus (beet western yellows virus).
Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, Compositae, Cruciferae, Solanaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Apium graveolens, Beta macrocarpa, Brassica campestris ssp. pekinensis, Brassica juncea, Chenopodium amaranticolor, Cichorium endiva, Conium maculatum, Coriandrum sativum, Datura stramonium, Daucus carota, Gomphrena globosa, Lycopersicon esculentum, Nicandra physalodes, Nicotiana tabacum, Petunia x hybrida, Raphanus sativus, Sonchus oleraceus.
Beta vulgaris, Spinacia oleracea, Nicotiana glutinosa, Physalis floridana no conspicuous systemic infection.
Chenopodium quinoa local lesions.
Nicotiana clevelandii faint interveinal chlorotic spotting of systemically infected leaves (especially under cool shady conditions). Diagnostic host: insusceptible host species Beta macrocarpa, Chenopodium amaranticolor, Datura stramonium, Nicotiana tabacum, Petunia x hybrida.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
