How do plant-associated microbiota regulate plant hormones, affecting their growth and development? This study reveals that bacterial isolates associated with the roots of Arabidopsis and rice can degrade the auxin indole-3-acetic acid (IAA), mitigat…
Tools "Here, we engineered tobacco rattle virus to carry the compact RNA-guided TnpB enzyme ISYmu1 and its guide RNA. This innovation allowed transgene-free editing of #Arabidopsis thaliana in a single step, with edits inherited in the subsequent generation.

Genome editing is transforming plant biology by enabling precise DNA modifications. However, delivery of editing systems into plants remains challenging, often requiring slow, genotype-specific methods such as tissue culture or transformation.
