In our latest study, we took a critical look at #fungal family #Nectriaceae by analyzing 1,530 #genomes! We built a robust #phylogenomic backbone that supports current taxonomy but also reveals gene-tree discordance and unresolved boundaries. More info www.biorxiv.org/content/10.6...

It’s been 14 years since I uploaded a video on YouTube showing that Striga does not infect other members of the Orobanchaceae family.JSPS Fellow Simon came to Japan and carried out mutant screening to find mechanism and it was 10 years ago that the mutant was finally obtained. A long journey.

I am happy to see this out!

Plant-microbe relationship (mutualistic, commensalistic, parasitic) is not fixed, but rather dynamic, depending on the specific context.
We summarize the current knowledge on this.

Hope you enjoy~

I'm very happy that this paper is now published in PNAS!

Isochorismate-based salicylic acid biosynthesis appears to have emerged in the Brassicales after the divergence of C. papaya, likely within the timeframe between the divergence of B. maritima and R. odorata.
