Fig. 1. Marker analysis of soybean lines possessing novel palmitic acid phenotypes. (A) PCR amplification products using FATB1a- and FATB1b-specific primers. Lines N79-2077 and N93-2008 are homozygous for the fapnc locus. (B) Southern blot analysis of XbaI-digested genomic DNA of the genotypes shown in (A) using GmFATB1a as the hybridization probe. Palmitic acid content for each line is indicated.
