Reprogramming trees: Hairy root-mediated transformation unlocks genetic engineering in poplar
Plant Science Research WeeklyAgrobacterium tumefaciens, through its natural capacity to deliver foreign DNA into plant genomes, has enabled efficient transformation across many plant species and cultivars. Despite these advancements, persistent challenges remain, including genotype-dependent recalcitrance, potential off-target DNA…
