... patterning in a non-cell autonomous manner, we generated seedlings with genetic mosaic sectors overproducing individual EPF and EPFL peptides of opposite biological functions: EPF1, which restricts stomatal development, and Stomagen, which promotes stomatal development ( Hara et al., 2007 ; Sugano et al...

... guidance, including those with essential functions during early development, we have devised a strategy for the simple and efficient generation of genetic mosaics in which mutant photoreceptor axons innervate a predominantly wild-type brain. In a large-scale saturation mutagenesis performed using...
