LITERATURE
evolution
-
SMT2 and SMT3 genes are highly homologous and encode highly similar sterol 24-carbon methyltransferases
malfunction
-
deficiency of SMT2 in the cvp1 mutant results in moderate developmental defects, including aberrant cotyledon vein patterning, serrated floral organs, and reduced stature, but plants are viable, suggesting that SMT3 activity can substitute for the loss of SMT2, overview. Mutation in both SMT2 and SMT3 causes extreme alteration in sterol composition, sterol profiles of smt mutants, overview. Mutants deficient in both SMT1 and SMT2 are embryo lethal.
