Annotated Information
Function
EUI gene is a recessive gene which was first reported by Rutger and Carnahan [1], which is characterized by the near doubling length of the uppermost internode, excess panicle exsertion and an increased panicle length in comparison with the wild type.The EUI mutant shows notably rapid elongation of the uppermost internode at the heading stage. Because of its prospective application to amend panicle enclosure in the male-sterile lines, this recessive trait, along with male sterility, maintainer and restorer, was referred to as the fourth genetic element of hybrid rice production [1].
The EUI1 gene was mapped on the central part of the long arm of chromosome 5, and located within two overlapping bacterial artificial chromosome (BAC) clones, OSJNBa0018K15 and OSJNBa0095J22, in an interval of 98 kb between markers M0387 and M01 [2].The EUI1 gene encodes a putative cytochrome P450 protein, CYP714D1. It can control the elongation of internodes and determines the plant height and underlies the grain yield (Luo et al., 2006).EUI1 plays a negative role in gibberellinmediated regulation of cell elongation in the uppermost internode of rice [3] [4].
