We found that cytokinin-induced LBDs drive radial (secondary) growth in Arabidopsis root by reshaping primary cell wall pectin, in part through four pectate-lyase-like genes. Huge congrats to the fantastic postdocs who led this work: Lingling Ye and Xin Wang. 1/x www.nature.com/articles/s41...
Cambium LBDs promote radial growth by regulating PLL-mediated pectin metabolism - Nature Plants
This study reveals that LBD transcription factors in the cambium drive radial plant growth by regulating PECTATE LYASE-LIKE (PLL) enzymes that remodel cell wall pectin, promoting cell expansion.

This might be one of the simplest images I captured, but very fascinating nonetheless, as it shows how tight the cytoplasm in a plant cell is. The cytosol and all other organelles are squished between the plasma membrane (magenta) and the central vacuole (its membrane is green)
