Interaction between host genotypes and pathogen strains

 

The following biplot is most appropriate for visualizing host by pathogen interactions:

 

 

The biplot is based on model 4 (double-centered) so that the main effects of the host and the pathogens are removed; anything you see is host by pathogen interaction, or specific virulence or vertical resistance.

 

This biplot shows the following:

 

 

 

 

 

 

 

To see the original data for the biplot, follow Functions for host by pathogen data

 

NOTE BUT: The use of the double-centered biplot is not recommended in all cases except for gene expression data. In most cases, G+GE must be considered together to make any sense in terms of entry evaluation or tester evaluation.
