Such observations led to the hypothesis that regulated expression of PL3 in transgenic potatoes could contribute to enhanced tissue disintegration during storage or thermal treatment. This report addresses the properties of several independent transgenic potato plant lines that express PL3, either constitutively or tuber-specific. We also describe the results obtained following application of Erwinia bacteria to wounded potato tubers. 

Conclusion. We have shown that PL3 induces plant responses against maceration caused by attacking Erwinia bacteria. It remains to be elucidated whether this is caused by an enforcement of host cell walls and/or the production of compounds directed against the invading bacteria and their enzymes.

Among the family of Enterobacteriaceae, two species of the genus Erwinia define the soft rot group E. chrysanthemi and E. carotovora. The main characteristic of the soft rot bacteria is their ability to produce large quantities of plant cell wall degrading enzymes. The maceration of plant tissue resulting from... 

Synthesis of New Methyl Esters of 3-Deoxy-D- ry /rro-2-hexulosonic acid (KDG) analogs, inducers of the Expression of Pectinase Genes in Bacteria Erwinia chrysanthemi... 

Fom- title compounds, 5-deoxy KDG Me estw, 5-epi KDG Me ester, 4-0-Me KDG Me ester and 4-deoxy KDG Me ester were prepared either from D-glucono-l,5-lactone or from 1,2 5,6 di-O-isopropylidene-D-mannitol. Biological tests perfcHined rat these molecules have shown that the compounds modified on the C-5 position (5-deoxy KDG Me ester and 5-epi KDG Me ester) are gratuitous inducers of the e>q>ression of pectinase genes in the phytopathogenic bacteria Erwinia Chrysanthemi when the C-4 modified molecules (4-0-Me KDG Me ester and 4-deoxy KDG Me ester) are not inducers. 

Studies focused on the determination of SAR have revealed that the different enantiomeric form of catechins apparently affects their antibacterial activity. Bais et al. [101] found that (-i-)-catechin inhibited soil-borne bacteria of the species Xanthomonas campestris, R fluorescens, and Erwinia caro-...

Erwinia spp. are commonly present on vegetables at harvest. This bacterium has the characteristic of producing extracellular enzymes that degrade plant cell walls. Moreover, many Erwinia spp. such as E. carotovora are capable of using compounds as energy that are normally not utilized by most common bacteria (Jay 1992). Moreover, these species produce many enzymes (such as pectate lyase, polygacturonase,...
