Nomenclature

Acronym

JMV.

ICTV decimal code

29.0.3.0.021

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Jatropha gossypiifolia, J. podagrica, J. multifida, Croton lobatus, Jacquemontia tamnifolia, Phaseolus vulgaris - yellow mosaics.

Transmission

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae. Transmitted in a semi-persistent manner. Virus lost by the vector when it moults; not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by seed.

Geographical distribution

Spreads in Kenya and Puerto Rico.

Susceptible host species

• Croton lobatus
• Jacquemontia tamnifolia
• Jatropha gossypiifolia
• Jatropha multifida
• Jatropha podagrica
• Phaseolus vulgaris

Families containing susceptible hosts

• Convolvulaceae (1/1)
• Euphorbiaceae (4/4)
• Leguminosae-Papilionoideae (1/1)

Physical and biochemical properties

Particle morphology

Virions geminate; not enveloped; 15-18 nm in diameter; 15 and 30 nm in length; rounded in profile; without a conspicuous capsomere arrangement.

Biochemical properties

Genome consists of DNA; single-stranded.

Replication

Genome replicates in nuclei.

Cytopathology

Virions found in leaves, phloem and companion cells; in nuclei; in sieve tubes. Inclusions present in infected cells; are crystals in the nucleus, or amorphous X-bodies (in cytoplasm), or unusual in shape; fibrillar bodies; they contain virions (in the nuclear inclusions), or they do not contain virions (in the cytoplasmic inclusions). Other cellular changes: the nucleolar segregation of granular and fibrillar components (Kim et al., 1986).

Taxonomy and relationships

bigeminivirus: Geminiviridae
