Nomenclature

Acronym

BaMV

ICTV decimal code

56.0.1.T.002

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Ten species of bamboo, Bambusa beecheyana, B. beecheyana cv. pubescens, B. edulis, B. multiplex, B. oldhamii, B. vulgaris, B. vulgaris cv. striata, Dendrocalamus latiflorus, D. latiflorus cv. Mei-nung, Phyllostachys nigra - mosaic, necrotic streaks on culms, vascular discoloration.

Transmission

Transmitted by means not involving a vector. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in the Pacific region; the Philippines and Taiwan. Found, but with no evidence of spread, in Brazil.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show mosaics, stunting.

Diagnostically susceptible host species and symptoms

• Gomphrena globosa, Chenopodium amaranticolor - necrotic local lesions; not systemic.
• Bambusa vulgaris cv. Vittatu, Dendrocalamus latiflorus cv. Mei-nung - systemic mosaic.

Diagnostically insusceptible host species

Phaseolus vulgaris, Capsicum annuum, Lycopersicon esculentum, Nicotiana tabacum cv. Turkish, Oryza sativa.

Maintenance and propagation hosts

Bambusa multiplex, B. vulgaris, Dendrocalamus latiflorus.

Assay hosts (Local lesions or Whole plants)

Gomphrena globosa (L), Chenopodium amaranticolor (L), Bambusa vulgaris cv. Vittatu (W), Dendrocalamus latiflorus cv. Mei-nung (W).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm and in cell vacuoles; vacuoles and attached to chloroplasts, as well as occurring abundantly in cytoplasm. Inclusions present in infected cells; are crystals in the cytoplasm and crystals in the nucleus; they do not contain virions.
