FIG. 4.
Cellular morphology of U. maydis strains carrying mutations at the ras2 locus. Wild-type strain 518 (top left), 001 Δras2 (top right), 001 Δras2 transformed with a vector control (pSat112, second from top left), 001 Δras2 transformed with a plasmid carrying the wild-type ras2 allele (pX696S, second from top right), P6D (third from top left), P6D Δras2 (third from top right), wild-type 518 transformed with a vector control (pHyg101, bottom left), and wild-type 518 transformed with a plasmid carrying the activated ras2Val16 allele (prV16Hyg, bottom right) are shown.
