Sequences essential for transmission of Spiroplasma citri by its leafhopper vector, Circulifer haematoceps, revealed by plasmid curing and replacement based on incompatibility.

Abstract excerpt

Spiroplasma citri GII3 contains highly related low-copy-number plasmids pSci1 to -6. Despite the strong similarities between their replication regions, these plasmids coexist in the spiroplasma cells, indicating that they are mutually compatible. The pSci1 to -6 plasmids encode the membrane proteins known as S. citri adhesion-related proteins (ScARPs) (pSci1 to -5) and the hydrophilic protein P32 (pSci6), which...
