Markings on the DNA help plant cells ‘remember’. Who they are. In what developmental stage they are. Their environment. Now a new study in Communications Biology by Chinese researchers shows that during the early stages of embryo development these DNA marks shift frequently.

A new regulatory element enables bacterial uptake by plant cells
Plants take up nitrogen fixing bacteria when they start a symbiosis with them. Now new research shows that it is not a specific gene, but a regulatory element of genes that allows plant to do this.
Hijacking flower genes to make galls
You have likely come across them, galls, deformities on leaves or stems. The larvae of various insects induce galls, varying from simple tissue deformities to complex structures. A new paper shows how the larvae inside hijack the plant genes to make those structures.
Regulation from a distance
Plant genomes in contrast to animal genomes don’t contain regulatory elements, or so was I led to believe. Now a new study “Two deeply conserved non-coding sequences control PLETHORA1/2 expression and coordinate embryo and root development” shows that plants also have those gene regulatory elements.
