construction of KASII knockout mutants by T-DNA disruption, knockout alleles fab1-1 and fab1-2, strong seed-specific hairpin-RNAi reductions in FAB1 expression resulted in abortion of about 1/4 of the embryos in an apparent phenocopy of fab1-2 homozygosity, in less severe FAB1 hairpin-RNAi individuals, embryos developed normally and exhibited a 1:2:1 segregation ratio for palmitate accumulation, thus, early embryo development appears sensitive to elevated 16:0, whereas at later stages, up to 53% of 16:0, i.e. a 7-fold increase over wild-type levels, is tolerated, Fab1-1 mutant plants show about 60% of wild-type enzyme activity and about 17% palm-like oil accumulation compared to the wild-type plants, phenotypes, overview |
