Phytic acid, myo-inositol (1, 2, 3, 4, 5, 6)-hexakisphosphate, is a material that plants store phosphorus in seeds. Phytic acid is classified as an antinutrient because of indigestibility. Non-ruminant animals, such as human and swine, excrete unavailable phytic acid. The unavailable phytic acid run off to ground water, river, sea, causing eutrophication as a factor. Accordingly, low-phytic acid crops draw the attention due to both nutritional and environmental reasons. Using more than 900 Glycine accessions including G. max, G. soja and G. gracillis, colormetric method was applied for detecting low-phytic acid mutant. Two hundred fifty accessions were screened by the colormetric method so far, but no mutant was identified. Screening of mutants with the rest 710 accessions is in progress. MIPS1 (D-myo-inositol 3-phosphate synthase) is considered as gene related to phytic acid content in soybean. Also, lpa1 (Zea mays low phytic acid 1) known as controlling phytic acid content in maize was recently reported that homologs of lpa1 were responsible for phytic acid content in soybean and located on linkage groups L and N (Chromosomes 19 and 3). After primers were designed from these three candidate genes for phytic acid content, identification of genes responsible for low phytic acid and investigation of genetic variation among 960 accessions will be performed as further study.

A single recessive gene, rxp, controls bacterial leaf pustule (BLP) resistance in a soybean. The Rxp locus appears to be linked to the malate dehydrogenase (Mdh) locus and Satt372 on linkage group (LG) D2. Around the Rxp locus, four bacterial artificial chromosome (BAC) clones are anchored by Satt486, Satt498, BARC-022037-04263, and BARC-040963-07870. Using these BAC clone sequences, possible orthologous region of Rxp locus was identified: Medicago truncatula contig 962 at chromosome 3 and contig 283 and contig 1108 at chromosome 8. Sequence analysis of contig 962 had revealed microsynteny with three soybean BAC clones on LG A1, which are duplicated with other two soybean BAC clones anchored by Satt486 and Satt498. After BLAST search was performed with M. truncatula contig 962 against soybean ESTs, several soybean ESTs were identified. With developed single nucleotide polymorphism (SNP) markers and the RIL population from the cross of Pureunkong and Jinpumkong 2, SNP genotyping was able to locate twos oybean ESTs: CO979743 at 1 cM away from Satt195 on LG C1 and BE021935 at 5 cM away from Satt363 on LG C2. Thus, our results indicate that structure of soybean genome around Rxp locus is very complicated.
