Abstract excerpt

We have used reverse-genetic analysis to investigate the function of MAP3K epsilon 1 and MAP3K epsilon 2, a pair of closely related Arabidopsis thaliana genes that encode protein kinases. Plants homozygous for either map3k epsilon 1 or map3k epsilon 2 displayed no apparent mutant phenotype, whereas the double-mutant combination caused pollen lethality. Transmission of the double-mutant combination through the...
