- ... Lethal yellowing (LY) group phytoplasma was detected in members of the Cedusa species of Derbids from Jamaica by nested PCR assay employing the rRNA primer pairs P1/P7 and LY16Sf/LY16Sr. A 1400-bp product was obtained from 13/43 Derbids that were analysed. Restriction fragment length polymorphism analysis of the nested PCR product revealed variations in 6/13 Derbids analysed, suggesting that the p ...

- ... Symptoms of leaf and stem chlorosis and plant stunting were common in sweetpotato plants (Ipomoea batatas) in farmers' fields in two widely separated locations, Kununurra and Broome, in the tropical Kimberley region in the state of Western Australia in 2003 and 2004. In the glasshouse, progeny plants developed similar symptoms characteristic of phytoplasma infection, consisting of chlorosis and a ...
