An interesting aspect of transcriptomics on plant-pathogen interactions. The data exists to say that plant hormones don't have synergistic or antagonistic interactions, instead it is a property of the output gene. For example, there are lots of genes in the datasets showing SA-JA synergism. #MPMI

STT3A Is Required for Recognition of Pathogen-Derived Sphingolipids in Arabidopsis | Molecular Plant-Microbe Interactions®
Plants recognize pathogen-associated molecular patterns (PAMPs) via pattern recognition receptors, leading to the activation of pattern-triggered immunity in response to pathogen attack. Phytophthora infestans ceramide D (Pi-Cer D) is a sphingolipid fro...

MPMI Terminology question - What simple phrasing would you use differentiate a plant response that happens to all members of a pathogen species versus the same plants response that is limited to one or a few pathogen genotypes in the species.

Crops often lack diverse resistance genes, making them vulnerable to rapidly evolving pathogens. Xiaoxiao Zhang et al. used DNA shuffling on barley Mla7 and Mla13 genes to create MLA variants, some gaining the ability to recognize the powdery mildew effector AVRA13: doi.org/10.1094/MPMI...

The closing talk is being delivered by Maria Harrison. Maybe showing my Cornell bias, but her work is amazing as is her mentorship (so I’ve heard).
Maria summarizes the progress and current state of the field of arbuscular mycorrhizal fungi: “the most important symbiosis in the world”.

Luis Rubio moves us from thinking about engineering against pathogens to engineering for nitrogen fixation.
They moved Nif genes into yeast mitochondria! But can this work in plants? Insolubiluty is the issue.
Screened variants by expressing in N benth - found one. Works in rice too!

The answer: Yes! New “mamp-ml”does pretty well.

Reiner van der Hoorn is first up on the last day of #2025ISMPMI.
Clever use of blue/white screening to identify a bacterial inhibitor of plant beta-galactosidase. Pseudomonas-produced glycoserin mimics galactose!
Also found that glycoserin production stems from purine biosynthesis.
