I am not sure whether I should put the Guard Hypothesis in this article or whether it deserves a page of it's own. (a Mentally Efficient Loonies And Nice Insane Elephants creation 13:35, 21 January 2007 (UTC))Reply

I would say that a separate article on the Guard Hypothesis would be a good idea with a comment in this article stating that it is possible explanation of the mechanism for some gene-for-gene relationships. Somanypeople 19:55, 21 January 2007 (UTC)Reply

I have put it in briefly here, and when I have the time I will create a full article (already drawn up some diagrams) with all the proper references and detailed discussion of the evidence. (a Mentally Efficient Loonies And Nice Insane Elephants creation 12:10, 22 January 2007 (UTC))Reply

The guard hypothesis contradicts the gene-for-gene paradigm - One gene is able to confer resistance to multiple elicitors and it is therefore not gene-for-gene. I think it should be moved to a new page personally. Smartse (talk) 15:22, 26 February 2009 (UTC)Reply

Done it - hope people agree! Smartse (talk) 15:22, 1 March 2009 (UTC)Reply

"If a host individual has several of these resistance genes, it is resistant to any parasite individual that lacks one or more of the matching genes for parasite ability. And it is susceptible to any parasite individual that has all (or more than all) of the matching genes"

Avr proteins are called that because they confer avirulence when infecting a plant with the cognate R gene.

Should it not read something more like "If a host individual has a specific R gene, it is resistant to any parasite individual that contains the cognate Avr gene. And will be susceptible to a parasite that lacks any corresponding Avr genes? Molymicro 22:46, 14 April 2007 (UTC)Reply

Plants producing a specific R gene product are resistant towards a pathogen that produces the corresponding Avr gene product. This sentance needs work. It doesn't work as it is.

Pathogens do not produce gene products

As the pathogen page says, it is "an infectious agent such as a virus, bacterium, prion, fungus, viroid, or parasite that causes disease in its host". Most of these produce gene products (prions don't). Sminthopsis84 (talk) 17:05, 7 April 2016 (UTC)Reply
