Overexpressing a maize lipoxygenase (ZmLOX4) boosts resistance to Fusarium infection.
Glad that our maize Gene editing & transformation platform, at @rdplab.bsky.social, contributed to this research, led by the Lanubile's Lab.

Yes indeed PI(4,5)P2 biosensor is enriched at the peri-germ cell membrane π (another parallel!), See the picture below.
It was published here: doi.org/10.1083/jcb.... but confusingly, the peri-germ cell membrane was called here pollen "endo-PM"...
Super nice images π
Fascinating question about membrane identity on these "specialized" membranes.
In a very different context, the peri-arbuscular and peri-germ cell membrane (in pollen) show some interesting parallels. π€ Lots to think about!...
