Reduction of bacterial leaf spot severity on radish, lettuce, and tomato plants grown in compost-amended potting mixes

J.H. Aldahmani; P.A. Abbasi; F. Sahin; et al. Canadian Journal of Plant Pathology 2005. doi:10.1080/07060660509507215

Other claims from this paper (12)

Intervention effect FCPB grown radish had less severe bacterial leaf spot than peat or vermiculite grown plants.
Intervention effect FCPB grown lettuce had less severe bacterial leaf spot than peat or vermiculite grown plants.
Intervention effect FCPB grown tomato had less severe bacterial leaf spot than peat or vermiculite grown plants.
Intervention effect Composted cow manure mix reduced disease severity in some tested plants.
Intervention effect Steam treated compost amended greenhouse soil reduced disease severity in some tested plants.
Intervention effect Infected tomato in compost amended substrate harbored smaller Xanthomonas campestris pv. vesicatoria populations.
Intervention effect Autoclaving removed FCPB disease suppression.
Intervention effect Reinoculating autoclaved FCPB with untreated FCPB restored disease suppression.
Observation Disease suppression varied among FCPB batches.
Observation Vermiculite consistently failed to suppress the diseases.
Observation Highly decomposed sphagnum peat consistently failed to suppress the diseases.
Recommendation The authors suggest FCPB or compost substrates may initially protect vegetable seedlings against bacterial leaf spot.

Characterization of AvrBs3-Like Effectors from a Brassicaceae Pathogen Reveals Virulence and Avirulence Activities and a Protein with a Novel Repeat Architecture

Sabine Kay; Jens Boch; Ulla Bonas Molecular Plant-Microbe Interactions 2005. doi:10.1094/mpmi-18-0838

Other claims from this paper (10)

Observation The isolated effector genes were designated hax2, hax3 and hax4.
Mechanism All three Hax proteins are translocated into plant cells through the type III secretion system.
Observation Hax3 and Hax4 have typical AvrBs3-like structure with central 34-amino-acid repeats.
Observation Hax2 has 35-aa repeats with an additional proline residue.
Observation Hax2 contains 21.5 repeats.
Observation Hax3 contains 11.5 repeats.
Observation Hax4 contains 14.5 repeats.
Association Individual genes differ in aggressiveness contribution, with hax2 strongest for chlorosis and necrosis.
Mechanism hax3 and hax4, but not hax2, confer Bs4-dependent avirulence in tomato.
Mechanism hax3 and hax4, but not hax2, confer avirulence in transgenic Nicotiana benthamiana expressing Bs4.
