General Information

General Information	Comment	Organism
malfunction	single spe-sdh mutants are isolated after sexual recombination in planta with a compatible wild-type strain. Mutants are auxotrophic for lysine and spermidine, but not for putrescine, and contain putrescine and spermidine, but not spermine. spe-sdh are were sensitive to stress, unable to carry out the yeast-to-mycelium dimorphic transition, and show attenuated virulence to maize. These phenotypic alterations are reverted by complementation with the wild-type gene	Ustilago maydis
