Other claims from this paper (15)
- Observation Sorghum line Tx2786, grown near sugarcane, was infected with a virus causing mosaic and necrotic symptoms in the 1994 postrainy season at Parbhani, India.
- Observation All sorghum lines, including those resistant to SrMV, SCMV, MDMV and JGMV, were infected by IBS.
- Observation IBS caused necrosis in the sorghum lines Cargill-40, Hegari, PI-35038, RTx09, Tx2786, QL-3 from India and Redlan.
- Observation IBS caused mosaic symptoms in the sorghum lines RTx430, SA-394, Atlas, Martin, BTx3048, Caprock, NM-31, QL-11, SCO-175-14E, Rio and BTx623.
- Observation Sorghum reactions to sorghum and sugarcane virus isolates were similar.
- Observation IBS infected maize (cv. African Tall) by sap transmission.
- Observation IBS infected johnsongrass (cv. 81) with symptomless infection.
- Observation IBS infected sorghum cv. CS-3541.
- Observation IBS was transmitted by the corn leaf aphid in a nonpersistent manner from sorghum and sugarcane to all 18 sorghum lines in a glasshouse.
- Observation IBS was serologically related to SrMV strains SCH and SCI.
- Observation IBS induced cytoplasmic cylindrical inclusions of pinwheels with laminated aggregates in sorghum and sugarcane host cells.
- Observation Leaf-dip electron microscopy of infected sorghum and sugarcane tissues revealed particles of 720 × 12 nm, typical of a potyvirus.
- Observation Purified IBS contained one major polypeptide of 40 kDa.
- Observation Purified IBS contained a ribonucleic acid of 3.0 × 10 6 Da.
- Observation IBS from field-infected sorghum Tx2786 and sugarcane Co.740 is identified as an immunity (QL3) breaking strain of SrMV (SrMV-IBS).
