Two deeply conserved non-coding sequences control PLETHORA1/2 expression and coordinate embryo and root development.

Conserved non-coding sequences (CNSs) are integral elements of transcriptional regulation. Transcriptional tuning of PLETHORA (PLT) genes that encode master regulators of plant development is vital for embryogenesis and meristematic function. However, how the expression of PLT genes is modulated through CNSs remains unclear.

Pioneer Arabidopsis thaliana spans the succession gradient revealing a diverse root-associated microbiome.

Background: Soil microbiomes are increasingly acknowledged to affect plant functioning. Research in molecular model species Arabidopsis thaliana has given detailed insights of such plant-microbiome interactions. However, the circumstances under which natural A.
