Mechanism of Photosynthesis Decrease by Verticillium dahliae in Potato

Robert L. Bowden; Douglas I. Rouse; Thomas D. Sharkey PLANT PHYSIOLOGY 1990. doi:10.1104/pp.94.3.1048

Other claims from this paper (7)

Intervention effect Infected symptomless potato leaves had reduced carbon assimilation, stomatal conductance and intercellular CO(2).
Intervention effect Infection did not increase dark respiration.
Intervention effect Infection did not change light use efficiency at constant intercellular CO(2).
Mechanism The authors attribute the initial photosynthetic decrease to stomatal closure.
Observation Patchiness in carbon assimilation was found at low frequency.
Association Low stomatal conductance correlated with low leaf water potentials.
Intervention effect Infection did not affect leaf osmotic potential.

Other claims from this paper (9)

Intervention effect Rhinanthus parasitism significantly decreased Phleum host biomass.
Intervention effect Parasitized Plantago had reduced maximum quantum yield versus controls.
Intervention effect Parasitized Phleum did not show reduced maximum quantum yield.
Association Rhinanthus on Phleum had significantly lower F(v)/F(m) than on Plantago.
Intervention effect Parasitism significantly depressed Phleum steady-state quantum yield.
Intervention effect Parasitism depressed Plantago steady-state quantum yield only at low irradiance.
Association Rhinanthus grown on Plantago had very low Phi(PSII), unlike Rhinanthus on Phleum.
Observation Authors interpreted Plantago as having apparent chemical and physical defenses against parasitism.
Mechanism Authors proposed electron transport rate as the limiting factor for biomass accumulation.

A Eukaryotic-Acquired Gene by a Biotrophic Phytopathogen Allows Prolonged Survival on the Host by Counteracting the Shut-Down of Plant Photosynthesis

Betiana S. Garavaglia; Ludivine Thomas; Natalia Gottig; et al. PLoS ONE 2010. doi:10.1371/journal.pone.0008950

Other claims from this paper (6)

Observation Both bacterial types downregulated photosynthesis enzymes and chloroplast ribosomal proteins in citrus.
Observation Both bacterial types upregulated defense-response proteins.
Intervention effect The XacPNP deletion mutant caused a more pronounced loss of photosynthetic proteins than the wild type.
Intervention effect The XacPNP deletion mutant did not reduce defense proteins relative to wild type.
Intervention effect Chlorophyll fluorescence showed a greater photosynthetic reduction with the mutant.
Mechanism The authors conclude that XacPNP counteracts host photosynthesis shutdown and prolongs bacterial survival.
