Plasmodesmata: Channels Under Pressure Annu. Rev. Plant Biol. (IF 23.9) Pub Date : 2024-03-01 Emmanuelle M. Bayer, Yoselin Benitez-Alfonso
Multicellularity has emerged multiple times in evolution, enabling groups of cells to share a living space and reducing the burden of solitary tasks. While unicellular organisms exhibit individuality and independence, cooperation among cells in multicellular organisms brings specialization and flexibility. However, multicellularity also necessitates intercellular dependence and relies on intercellular

Leaf Vein Patterning Annu. Rev. Plant Biol. (IF 23.9) Pub Date : 2024-02-22 Enrico Scarpella
Leaves form veins whose patterns vary from a single vein running the length of the leaf to networks of staggering complexity where huge numbers of veins connect to other veins at both ends. For the longest time, vein formation was thought to be controlled only by the polar, cell-to-cell transport of the plant hormone auxin; recent evidence suggests that is not so. Instead, it turns out that vein patterning
