The fungal elicitor cryptogein is a sterol carrier protein.
TLDR
The results show that cryptogein has one binding site with strong affinity for dehydroergosterol, and this protein catalyzes the transfer of sterols between phospholipidic artificial membranes, the first evidence for the existence of an extracellular sterol carrier protein and for a molecular activity of Cryptogein.About:

A Catalogue of the Effector Secretome of Plant Pathogenic Oomycetes
TL;DR: This review classifies and catalogues the effector secretome of oomycetes, a phylogenetically distinct group of eukaryotic microorganisms that includes some of the most notorious pathogens of plants.
Journal ArticleDOI
Molecular basis of recognition between phytophthora pathogens and their hosts
TL;DR: Recognition is the earliest step in any direct plant-microbe interaction and both host-specific and host-nonspecific factors influence zoospore taxis, encystment, cyst germination, and hyphal chemotropism in guiding the pathogen to potential infection sites.

Elicitation: A Tool for Enriching the Bioactive Composition of Foods
TL;DR: Understanding how plant tissues and their specific secondary metabolic pathways respond to specific treatments with elicitors would be the basis for designing protocols to enhance the production of secondary metabolites, in order to produce quality and healthy fresh foods.

TL;DR: It is proposed that elicitins could interact with regulating cell wall proteins before they reach the plasma membrane, and the plant reactivity or nonreactivity status could result from the equilibrium reached during this interaction.

Initial assessment of gene diversity for the oomycete pathogen Phytophthora infestans based on expressed sequences.
TL;DR: Four novel cDNAs containing sequences related to elicitins, a family of structurally related proteins that induce the hypersensitive response and condition avirulence of P. infestans on Nicotiana plants, were among the most notable genes identified.

TL;DR: Fungi constitute a highly versatile group of eukaryotic carbonheterotrophic organisms that have successfully occupied most natural habitats but what mechanisms control the degree of virulence on the host once pathogenicity has been established?

TL;DR: Both cryptogein and capsicein protect tobacco against invasion by the pathogen Phytophthora nicotianac, the agent of the tobacco black shank, that is unable to produce such an elicitor.

TL;DR: Results suggest that protein phosphorylation followed by Ca2+ influx might be involved in the initial steps of cryptogein signal transduction, since ethyleneglycol-bis([beta]-amino-ethyl ether)-N,N[prime]-tetraacetic acid or La3+, which block Ca2+.

Sterols in Growth and Reproduction of Fungi
TL;DR: The elegant study by McCorkindale and co-workers shows that species of the Sapro legniales· and Leptomitales may be expected to contain cholesterol, desmos terol, 24-methylenecholesterol, or fucosterol rather than compounds such as ergosterol which have a pair of conjugated double bonds in ring B.
