Description of bacterial genes referenced in texts.
| Gene Name | Function | Relevant Bacterium | Importance |
|---|---|---|---|
| tolC | Outer membrane component of type I secretion system | X. fastidiosa | Knockout causes avirulence and hypersensitivity to phytoalexins |
| rpf gene cluster | Diffusible signal factor (XfDSF) synthesis and recognition | X. fastidiosa | Expression in grapevine reduces X. fastidiosa spread |
| lesA | Lipase/esterase | X. fastidiosa | Key pathogenicity factor for X. fastidiosa |
| pilA2 & pilC | Type 4 pili proteins | X. fastidiosa | Involved in biofilm formation |
| xadA1 & xadA2 | Afimbrial adhesins | X. fastidiosa | Involved in biofilm formation |
| mopB | X. fastidiosa outer membrane protein | X. fastidiosa | Deletion affects biofilm formation and virulence, eliminates twitching motility |
| luxI | Encodes enzymes that produce acyl-homoserine lactone (AHL) molecules | C. Las | C. Las lacks a luxI gene |
| luxR | AHL-responsive regulatory gene | C. Las | C. Las possesses a luxR gene |
| hxfA | Hemagglutinin-like | X. fastidiosa | Deletion results in hypervirulence; plants expressing the gene had decreased disease development |
| lasAI & lasAII | Type V autotransporters | C. Las | Found in C. Las genome; may target plant mitochondria |
