This paper identifies BpLAZY1A as a key gene regulating gravitropic signaling and tissue polarity in silver birch branches, linking gene expression asymmetry to biomechanical reinforcement and growth orientation.

The paper shows that increasing polyamine thermospermine transport with cytokinin reprograms xylem identity from woody to fleshy in Arabidopsis.

The paper shows plasmodesmata function as ER-PM tubular membrane contact sites that regulate intercellular molecular exchange in plants through PI4P and MCTP proteins.
