A single amino-acid substitution in the iron-sulphur protein subunit of succinate dehydrogenase determines resistance to carboxin in Mycosphaerella graminicola.
A gene encoding the iron-sulphur protein (Ip) subunit of succinate dehydrogenase (Sdh, EC 18.104.22.168) from Mycosphaerella graminicola (Septoria tritici) has been cloned andsequenced. The deduced amino-acid sequence exhibited a high degree of homology to Ip subunits of Sdh from other organisms; three cysteine-rich clusters associated with the iron-sulphur centres involved in electron transport were particularly conserved. Expression studies using a synthetic green fluorescent protein (SGFP) expr...Expand abstract
