Transposable elements are vectors of recurrent transgenerational epigenetic inheritance
DNA methylation loss at transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants and significance of this additional system of inheritan...

How parasitic plants avoid being parasitized | Plantae
It’s not too difficult to envision how a plant recognizes something very different from itself, like a bacterium, oomycete, or fungus. It’s a bit less obvious how a plant recognizes another plant as…

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.

Orobanche cumana in the USA!
The WSDA is on the hunt for a new crop pest, parasitic plant Orobanche cumana (aka 'SBR' or sunflower broomrape).
Thanks, iNaturalist community, O. cumana was ID'ed for the 1st time in North America in Yakima County. O. cumana is an agronomic pest and could destablilize native plant ecosystems.
