Yi-Qiang Cheng; Joong-Hoon Ahn; Jonathan D. Walton Microbiology 1999. doi:10.1099/00221287-145-12-3539

Other claims from this paper (7)

Observation TOXF was identified as a new gene of the TOX2 locus.
Mechanism TOXF is specifically required for HC-toxin production and pathogenicity.
Observation TOXF has two or three copies in toxin producing isolates and is absent in nonproducing strains.
Observation Deduced TOXF sequence had moderate homology with branched chain amino acid transaminases.
Intervention effect Disrupting every TOXF copy eliminated fungal HC-toxin production.
Intervention effect Disrupting every TOXF copy eliminated fungal pathogenicity.
Mechanism The authors propose that TOXF participates in HC-toxin synthesis, perhaps by aminating an Aeo precursor.

Sanjay Swarup Molecular Plant-Microbe Interactions 1992. doi:10.1094/mpmi-5-204

Other claims from this paper (12)

Intervention effect Introducing pthA into X. phaseoli and X. campestris pv. malvacearum left the transconjugants nonpathogenic to citrus.
Intervention effect Introducing pthA into X. phaseoli transconjugants elicited a hypersensitive response on bean.
Intervention effect Introducing pthA into X. campestris pv. malvacearum transconjugants elicited a hypersensitive response on cotton.
Intervention effect In X. c. pv. malvacearum, pthA conferred cultivar-specific avirulence on cotton.
Observation pthA is highly similar in structure to avrBs3 and avrBsP.
Intervention effect The pthA::Tn5-gusA mutant B21.2 of X. citri lost the ability to induce the nonhost HR on bean.
Intervention effect Introduction of cloned pthA restored the ability of B21.2 to elicit an HR on bean.
Mechanism The genetics of the nonhost HR may be the same as in homologous interactions involving specific avr genes.
Intervention effect Elimination of pthA function did not result in water-soaking or moderate growth of X. citri on bean.
Mechanism The nonhost HR may not limit the host range of X. citri on bean.
Mechanism The nonhost HR may not be responsible for the resistance of bean to X. citri.
Mechanism The pleiotropic avirulence function of pthA and the heterologous HR of bean to X. citri are evidently gratuitous.
