Plant J. 19:1999;163-171. The authors report that a phytoalexin-deficient mutant of Arabidopsis was more susceptible to one necrotrophic fungal pathogen than another. The work provides rare proof that a nonspecific defense mechanism can act as a resistance mechanism in vivo, and that it acts differentially on different pathogens.

Eur J Biochem. 265:1999;556-563. authors show that modifying different amino acids of the cysteine protease inhibitor independently abolished or enhanced the anti-fungal or protease inhibitory activity of the protein. This observation supports the concept that single nonspecific plant defenses may have a multiplicity of defensive functions and be subject to multiple selective pressures.

Biochemical characterization, radiation inactivation experiments, and covalent binding of elicitin to binding sites on plasma membranes were used to identify a glycoprotein-binding site on the plasma membranes of tobacco plants that were sensitive to the elicitor. They were also used to demonstrate elicitor-binding sites on the plasma membranes of Acerand Arabidopsis cells that were insensitive to the elicitor. These results suggest that binding sites for elicitors may be conserved among different plant species, irrespective of whether the plant cell shows a typical defense response.

This paper reports that an elicitor from yeast and several commercial cellulolytic enzymes contain components that cause transmembrane ion fluxes in artificial lipid bilayers. The authors raise the possibility that some nonspecific elicitors may not require a receptor-based mechanism for their activity.

EMBO J. 18:1999;4689-4699. Using in situ RNA hybridizations and transient expression studies, the parsley transcriptional activator WRKY1 was shown to mediate fungal elicitor-induced gene expression by binding to W-box elements, as well as binding to a specific arrangement of W-box elements in the WRKY1 promotor itself. This is the first in vivo functional characterization of the regulation of part of a nonspecific elicitor-induced gene activation cascade.

Synthetic peptides comprising 15-22 amino acids of the most highly conserved domain within the amino terminus of eubacterial flagellin were shown to act as elicitors of defense responses in the cells of several plant species when present in nanomolar concentrations. This is the first report of a general bacterial component acting as a nonspecific elicitor of defense responses in plants.

Crosses between Arabidopsis ecotypes that are, or are not, sensitive to peptides corresponding to a conserved domain of eubacterial flagellin revealed that a dominant locus is responsible for sensitivity to this peptide. This locus maps to a chromosome region that contains a cluster of R genes, raising the possibility that nonspecific elicitors can be perceived by a recognition process similar to that involved in host resistance.

Transgenic tobacco plants with reduced capability to detoxify reactive oxygen intermediates are hyperresponsive to pathogen infection. Proc Natl Acad Sci USA. 96:1999;14165-14170. Ion leakage was examined in plants treated with high oxygen pressure and in transgenic tobacco plants expressing antisense RNA for ascorbate peroxidase or catalase; plants were inoculated with a bacterial pathogen of beans. This is one of the few in planta demonstrations of a role for ROS in the expression of a nonhost hypersensitive response.

25. L and Ced-9 inhibit cell death in tobacco plants. Curr Biol. 9:1999;775-778. The authors report that the expression of a mammalian or a nematode suppressor of programmed cell death in tobacco plants results in reduced cell death in response to UV-B irradiation, paraquat treatment, or virus infection. This is one of a number of reports published in 1999 suggesting that components of the programmed cell death in animals may function in plant cells. These reports also suggest that the hypersensitive response seen in examples of both host and nonhost resistance to microbial pathogens may be regulated in a similar manner to death caused by abiotic stresses.
26. Lacomme C., Santa Cruz S. Bax-induced cell death in tobacco is similar to the hypersensitive response. Proc Natl Acad Sci USA. 96:1999;7956-7961. It is shown that the expression of a death-promoting mammalian gene triggers cell death and the accumulation of the defense-associated protein PR1 when expressed in tobacco from a virus vector. The hypothesis that the gene activates an endogenous cell-death program is supported by the fact that this death is blocked by a protein phosphatase inhibitor, as is virus-induced hypersensitive cell death.

Mol Plant Microbe Interact. 12:1999;479-489. The authors report that the accumulation of transcripts of a putative pathogenesis-related protein, and an enzyme involved in phytoalexin synthesis, was delayed when sorghum was inoculated with a fungus for which it was a host compared with a fungus for which it was a nonhost. In the latter, rapid accumulation of both transcripts occurred prior to the fungus entering the cell lumen. As well as being one of relatively few direct studies of nonhost resistance, this paper provides evidence of the importance of plant responses during the earliest stages of cell-wall penetration in nonhost resistance to fungal pathogens.

Plant J. 17:1999;523-534. Autofluorescent phenolic compounds were identified that accumulate on and in the cell wall at sites of attempted, but unsuccessful, fungal penetration in association with increased peroxidase activity and a rearrangement of the actin cytoskeleton. This paper provides rare biochemical detail to our knowledge of non-specific wall-associated defense responses to fungal pathogens.
