Gene Details:

• Gene ID: Zm00001eb396990
• Gene Symbol: THP9 asn4 asnB
• Gene Name: asparagine synthetase4
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• THP9-teosinte seems to increase nitrogen-use efficiency, which is important for promoting a high yield under low-nitrogen conditions.
• Here we use trio binning to create a contiguous haplotype DNA sequence of a teosinte (Zea mays subsp. parviglumis) and, through map-based cloning, identify a major high-protein quantitative trait locus, TEOSINTE HIGH PROTEIN 9 (THP9), on chromosome 9.
• THP9 enhances seed protein content and nitrogen-use efficiency in maize.
• THP9 is a major QTL that influences the variation of seed protein content among inbred lines.
• THP9 encodes an asparagine synthetase.
