How Plants Shut out Bacteria
Unlike animals, which breathe through airways lined with pathogen-trapping defenses, plants get air through tiny pores in their leaves that all but invite bacteria to sneak in. How, then, do plants keep them out? They slam their pores, or stomata, shut. Stomata are flanked by guard cells that swell when triggered by bacteria, thus closing the pores. Besides being fascinating in its own right, t...
متن کاملOxalate-degrading bacteria can protect Arabidopsis thaliana and crop plants against botrytis cinerea.
Botrytis cinerea and Sclerotinia sclerotiorum secrete oxalic acid as a pathogenicity factor with a broad action. Consequently, it should be possible to interfere with the infection process by degrading oxalic acid during the interaction of these pathogens with their hosts. We have evaluated the potential of oxalate-degrading bacteria to protect plants against pathogenic fungi. Such bacteria wer...
متن کاملPhishing: How an Organization can Protect Itself
The objective of this paper is to report on research to construct a model, which should provide guidance to an organization on how to address all dimensions associated with phishing and assist in solving the problem holistically. The emphasis will be placed on the human and organizational dimensions. Most research in this area has shown that only certain dimensions used to combat phishing attac...
متن کاملHow Bacteria in Our Bodies Protect Our Health
Biologists once thought that human beings were physiological islands, entirely capable of regulating their own internal workings. Our bodies made all the enzymes needed for breaking down food and using its nutrients to power and repair our tissues and organs. Signals from our own tissues dictated body states such as hunger or satiety. The specialized cells of our immune system taught themselves...
متن کاملHow bacteria protect themselves against channel-forming colicins.
Here we review the mechanisms that bacterial cells use to protect themselves against channel-forming colicins. Four mechanisms are examined: immunity, resistance, tolerance and PacB character. Immunity confers protection to colicinogenic cells against the colicin they produce, since the colicinogenic plasmid bears the genetic determinant for such immunity protein. Resistance is provided by modi...
