Bittner-Eddy, P.D., Grenville-Briggs, L.J., Meitz, J.C., Rehmany, A.P., Rose,
L.E., and Beynon, J.L. (2004). Host-parasite coevolutionary conflict between
Arabidopsis and downy mildew. Science 306, 1957-1960.
This paper
reported the cloning of the avirulence gene, ATR13, that triggers
RPP13-mediated resistance. The authors showed that diversifying selection acts
on both the R and the cognate Avr gene, providing the first piece of molecular evidence
for coevolution of R and Avr.

Arabidopsis innate immunity. Nature 415, 977-983.
This paper
identified the first complete MAPK signaling cascade that function downstream
of the flagellin receptor FLS2, a leucine-rich-repeat (LRR) receptor kinase involved
in plant innate immunity.

Ausubel, F.M.
(2005). Are innate immune signaling pathways in plants and animals conserved?
Nat Immunol 6, 973-979.
A nice recent
review on plant innate immunity in which the author suggests that the analogous
regulatory modules used by plants and animals may be a consequence of
convergent evolution rather than an ancient common origin.

of brassinosteroids by the extracellular domain of the receptor kinase BRI1.
Science 288, 2360-2363.
A well-conceived
domain-swapping experiment to test the hypothesis that it is the LRR domain
that determines the ligand-binding specificity.

Kim, M.G., da
Cunha, L., McFall, A.J., Belkhadir, Y., DebRoy, S., Dangl, J.L., and Mackey, D.
(2005). Two Pseudomonas syringae type III effectors inhibit RIN4-regulated
basal defense in Arabidopsis. Cell 121, 749-759.
This paper
provided evidence to suggest that there is mechanistic link between basal
resistance and R gene-mediated resistance.
·
** Moffett, P.,
Farnham, G., Peart, J., and
An elegant
analysis to show that there is intra-molecular interaction between different
domains in the CC-NBS-LRR protein Rx.
A breakthrough in understanding how R
proteins may work.
·
** Mou, Z., Fan,
W., and Dong, X. (2003). Inducers of plant systemic acquired resistance
regulate NPR1 function through redox changes. Cell 113, 935-944.
This paper
filled the gap from the central regulatory protein NPR1 to activation of
defense genes. It showed that upon pathogen infection, NPR1 changes from
oligomer to monomer and enters to the nucleus where it binds to TGA
transcription factor to enhance PR gene expression.
·
** Rooney, H.C.,
Van't Klooster, J.W., van der Hoorn, R.A., Joosten, M.H., Jones, J.D., and de
Wit, P.J. (2005). Cladosporium Avr2 inhibits tomato Rcr3 protease required for
Cf-2-dependent disease resistance. Science 308, 1783-1786.
An excellent paper
reporting that the Rcr3 is the host target of Avr2 and Cf2 may “guard” Rcr3,
providing strong evidence for “the guard hypothesis”.

the above paper but in a different context.

An elegant study that identified the
bacterium type III effectors avrPto and avrPtoB suppress nonhost defense
signaling upstream of a MAPK cascade, revealing a fundamental role of MAMP

P. (2006). Nuclear Activity of MLA Immune Receptors Links Isolate-Specific and
Basal Disease-Resistance Responses. Science.
This work demonstrated that the coiled-coil
domain of a group of barley CC-NBS-LRR proteins interacts with two WRKY
transcription factors in the nucleus upon R-Avr recognition and de-repress
their function in negative regulation of basal resistance, thus linking the
R-gene specific resistance to basal
resistance.
