The authors introduce the ENABLE(R) Gene Editing in planta toolkit, a streamlined two‑step cloning system for creating CRISPR/Cas9 knockout vectors suitable for transient or stable transformation. Validation was performed in Oryza sativa protoplasts and Arabidopsis thaliana plants, and the toolkit includes low‑cost protocols aimed at facilitating adoption in the Global South.

The study demonstrates that ethylene signaling contributes to host resistance against the root parasitic plant Phelipanche aegyptiaca, as both water stress and parasitism activate ethylene responses in Arabidopsis roots. Application of the ethylene precursor ACC reduced parasite attachment, and mutants in ethylene signaling components (ETR1, CTR1) showed altered tolerance, highlighting ethylene-mediated defenses as a potential strategy for crop protection.

The study demonstrates that a beta‑1,3‑glucan‑binding protein from the rice blast fungus Magnaporthe oryzae interacts with the rice thaumatin‑like protein OsPR5, which sequesters the fungal protein to trigger immunity, while the fungus secretes thaumatin‑binding proteins to counteract this defense. Additionally, a rice cell‑surface receptor kinase containing a thaumatin domain has evolved to detect the fungal GBP, highlighting a complex coevolutionary arms race in the rice apoplast.
