This invention discloses a Zmhppd1
gene for detecting gamma-
tocotrienol content in sweet corn kernels and its application. The locus is the
InDel site at position 86086906 on
chromosome 5 of the sweet corn
genome, with a polymorphism of - / TAGAACAAGG. This locus is positively correlated with the expression of the 4-hydroxyphenylpyruvate
dioxygenase gene, thus affecting gamma-
tocotrienol content. This invention utilizes a
molecular marker developed based on the 4-hydroxyphenylpyruvate
dioxygenase gene (Zmhppd1) locus, employing
agarose gel electrophoresis technology.
Genotyping can be rapidly performed, offering advantages such as low cost, ease of operation, and suitability for high-
throughput detection. This locus will greatly promote
biofortification breeding of sweet corn with high gamma-
tocotrienol content. This invention, based on the 4-hydroxyphenylpyruvate
dioxygenase gene locus, allows for rapid
genotyping, offering advantages such as low cost, ease of operation, suitability for high-
throughput detection, and promotion of
biofortification breeding of sweet corn with high gamma-tocotrienol content.
