Piece de resistance: novel classes of plant disease resistance genes

Article Abstract:

Cloning of four new plant resistant (R) genes gives an insight into the molecular components of plant-pathogen interactions. The four R genes are RPS2 from Arabidopsis, N from tobacco, Cf-9 from tomato and L6 from flax. The diversity in R genes can be attributed to structural differences in genome organization at the loci of R genes. Recombination is mediated by R gene sequences, which might give rise to novel, altered or aberrently regulated R genes due to intragenic recombination or unequal crossing over.

Recognition of the bacterial avirulence protein AvrBs3 occurs inside the host plant cell

Article Abstract:

The role of the avrBs3 avirulence gene of Xanthomonas campestris pv. versicatoria in the recognition of resistant host plants was analyzed in pepper plant cells with Bs3 resistance genes. The pepper plant cells with BS3 genes exhibited hypersensitive apoptosis after the induction of avrBS3 genes. AVRBs3-mediated hypersensitive reaction on BS3 pepper plant cells also involved the activity of functional nuclear localization signals from the C-terminal region of the protein.

Eukaryotic fatty acylation drives plasma membrane targeting and enhances function of several type III effector proteins from Pseudomonas syringae

Article Abstract:

Several type III effector proteins from Pseudomonas syringae have been shown to be targeted to the host plasma membrane. In the same study it was shown that efficient membrane association enhances function. Plant innate immune systems evolved disease resistance genes to recognize some type III effectors, Avirulence (Avr) proteins.
