Data point to the existence of at least two separate hormone-dependent defense pathways in Arabidopsis that contribute to resistance against distinct microbial pathogens.
Sclerotinia sclerotiorum (Lib.) de Bary: biology and molecular traits of a cosmopolitan pathogen.
This review summarizes current knowledge of mechanisms employed by the fungus to parasitize its host with emphasis on biology, physiology and molecular aspects of pathogenicity.
Pathogen-induced systemic activation of a plant defensin gene in Arabidopsis follows a salicylic acid-independent pathway.
The results indicate that systemic pathogen-induced expression of the plant defensin gene in Arabidopsis is independent of salicylic acid but requires components of the ethylene and jasmonic acid response.

It is concluded that both the ethylene and jasmonate signaling pathways need to be triggered concomitantly, and not sequentially, to activate PDF1.2 upon pathogen infection.
Of PAMPs and Effectors: The Blurred PTI-ETI Dichotomy[OA]
It is argued that plant resistance is determined by immune receptors that recognize appropriate ligands to activate defense, the amplitude of which is likely determined by the level required for effective immunity.
Genetic Dissection of Verticillium Wilt Resistance Mediated by Tomato Ve11[C][W][OA]
It is shown that Ve1, but not Ve2, provides resistance in tomato against race 1 strains of V. albo-atrum and not against race 2 strains, and Ve1-mediated resistance signaling only partially overlaps with signaling mediated by Cf proteins, type members of the receptor-like protein class of resistance proteins.
Physiology and molecular aspects of Verticillium wilt diseases caused by V. dahliae and V. albo-atrum.
Although genetic resistance has been described in several plant species, only one resistance locus against Verticillium has been cloned to date and the molecular processes underlying this physiology remain largely unknown.
The BRI1-Associated Kinase 1, BAK1, Has a Brassinolide-Independent Role in Plant Cell-Death Control
Analysis of Two in Planta Expressed LysM Effector Homologs from the Fungus Mycosphaerella graminicola Reveals Novel Functional Properties and Varying Contributions to Virulence on Wheat1[W][OA]
Different functions for MgLysM effector homologs during plant infection are highlighted, including novel activities that distinguish these proteins from C. fulvum Ecp6.
Interfamily transfer of a plant pattern-recognition receptor confers broad-spectrum bacterial resistance
The results in controlled laboratory conditions suggest that heterologous expression of PAMP recognition systems could be used to engineer broad-spectrum disease resistance to important bacterial pathogens, potentially enabling more durable and sustainable resistance in the field.
