Coronatine Facilitates Pseudomonas syringae Infection of Arabidopsis Leaves at Night. [PDF]
, 2016 In many land plants, the stomatal pore opens during the day and closes during the night. Thus, periods of darkness could be effective in decreasing pathogen penetration into leaves through stomata, the primary sites for infection by many pathogens ...

Cloning and Mapping of a Putative Barley NADPH-Dependent HC-Toxin Reductase
Molecular Plant-Microbe Interactions, 1997 The NADPH-dependent HC-toxin reductase (HCTR), encoded by Hm1 in maize, inactivates HC-toxin produced by the fungus Cochliobolus carbonum, and thus confers resistance to the pathogen. The fact that C.

Syringomycin, a Bacterial Phytotoxin, Closes Stomata [PDF]
Plant Physiology, 1989 The effects of the bacterial phytotoxin, syringomycin, on stomata were investigated using detached leaves of Xanthium strumarium and isolated epidermes of Vicia faba. Syringomycin is known to cause K(+) efflux in fungal and higher plant cells. Doses of syringomycin as low as 0.3 unit per square centimeter (about 0.88 pmole per square centimeter ...

The CebE/MsiK transporter is a doorway to the cello-oligosaccharide-mediated induction of Streptomyces scabies pathogenicity [PDF]
, 2016 Streptomyces scabies is an economically important plant pathogen well-known for damaging root and tuber crops by causing scab lesions. Thaxtomin A is the main causative agent responsible for the pathogenicity of S.

Secondary metabolites in fungus-plant interactions [PDF]
, 2015 Fungi and plants are rich sources of thousands of secondary metabolites. The genetically coded possibilities for secondary metabolite production, the stimuli of the production, and the special phytotoxins basically determine the microscopic fungi-host ...

Assessing stomatal response to live bacterial cells using whole leaf imaging. [PDF]
, 2010 Stomata are natural openings in the plant epidermis responsible for gas exchange between plant interior and environment. They are formed by a pair of guard cells, which are able to close the stomatal pore in response to a number of external factors ...
