Mycorrhizal signals promote root development dependent …
As for the OsMYR1-OE lines, the overexpression of OsMYR1 may have already sufficiently promoted root development, rendering CO4 treatment redundant in further enhancing lateral root formation. In line with this interpretation, the number of lateral roots observed in OsMYR1 -OE plants was akin to that in the wild-type subjected to CO4 treatment.
