Plants have veins that transport nutrients through their body. These veins are highly organized. The hormone auxin travels directionally from cell-to-cell and provides cells with positional information, coordinating them during vein formation and regeneration. Scientists now discovered how cells translate auxin signals into forming a complex system of veins. This phenomenon also applies to wound healing and might lead to more mechanically resistant plants and further agricultural implications.
