The circadian clock regulates receptor-mediated immune responses to an herbivore-associated molecular pattern.

Plants activate induced defenses through the recognition of molecular patterns. Like pathogen-associated molecular patterns (PAMPs), herbivore-associated molecular patterns (HAMPs) can be recognized by cell surface pattern recognition receptors leading to defensive transcriptional changes in host plants. Herbivore-induced defensive outputs are regulated by the circadian clock, but the underlying molecular mechanisms remain unknown.

Signatures of plant defense response specificity mediated by herbivore-associated molecular patterns in legumes.

Chewing herbivores activate plant defense responses through a combination of mechanical wounding and elicitation by herbivore-associated molecular patterns (HAMPs). HAMPs are wound response amplifiers; however, specific defense outputs may also exist that strictly require HAMP-mediated defense signaling. To investigate HAMP-mediated signaling and defense responses, we characterized cowpea (Vigna unguiculata) transcriptome changes following elicitation by inceptin, a peptide HAMP common in Lepidoptera larvae oral secretions.

Comprehensive Time-Series Analysis of the Gene Expression Profile in a Susceptible Cultivar of Tree Tomato () During the Infection of .

is a tree from the Andean region bearing edible fruits, considered an exotic export. Although there has been renewed interest in its commercialization, sustainability, and disease management have been limiting factors. is a recently described species that causes late blight in .

Effector Repertoire of : In Search of Possible Virulence Factors Responsible for Its Host Specificity.

is an oomycete plant pathogen closely related to It infects tree tomato () in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of its sister species . We characterized, and compared the effector repertoires of and other species. To this end, we used approaches to predict and describe the repertoire of secreted proteins in species and determine unique and core effectors.
