Burkholderia glumae. [Descriptions of Fungi and Bacteria].
A description is provided for Burkholderia glumae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Oryza sativa. Andropogon virginicus, Arundinella hirta, Beckmannia syzigachne, Chloris gayana, Coix lacryma-jobi, Eleusine coracana, E. indica, Eragrotis curvula, E. multicaulis, Lolium multiflorum, Panicum coloratum, P. dichotomiflorum, P. maximum, Paspalum distichum, P. dilatatum, Pennisetum alopecuroides, Phleum pratense, Phragmites communis and Setaria viridis var. minor have all been recognised as new hosts (68, 4324). DISEASE: Bacterial grain and seedling rot of rice. The grains rot in the pannicles after 'heading'. Severely diseased pannicles may form infection foci for disease dissemination (Tsushima & Naito, 1991). The bacteria are thought to enter through the stoma on the inner surface of the rice husk and then multiply in the intercellular space of parenchyma (69, 1652). There is some evidence to suggest that degradative enzymes (72, 6749) and toxin production may also have a role in phytopathogenicity (69, 2349). GEOGRAPHICAL DISTRIBUTION: Sri Lanka (69, 4949), China, Japan, Taiwan (63, 3360), Colombia (70, 2670), Latin America in general (69, 1080; 70, 827). TRANSMISSION: Latent infection of rice seeds (70, 7648).
