The application belongs to the technical field of genetic engineering, and particularly relates to a ten-ploid long-spike Aegilops tauschii introgression gene ThpFBX1 and application thereof in regulating the heading stage of wheat. The amino acid sequence of the ten-ploid long-spike Aegilops tauschii introgression gene ThpFBX1 is shown as SEQ ID No. 1, and the nucleotide sequence is shown as SEQ ID No. 2. The ten-ploid long-spike Aegilops tauschii introgression gene ThpFBX1 is introduced into a recipient plant to obtain a transgenic plant overexpressing the ThpFBX1 gene, and experiments show that the overexpressing wheat exhibits early heading, and the ThpFBX1 gene can significantly advance the heading stage of the wheat.

The application discloses a tetraploid long-spike Aegilops tauschii salt-tolerant 3EL chromosome molecular marker and application thereof, and belongs to the technical field of crop genetic breeding. LTTE3EM-2 and LTTE3EZ-1 ) and a specific molecular marker of a long arm of a 6A chromosome of common wheat ( LTTAE6A-2 ) are combined into two groups of molecular markers ( LTTE3EM-2 and LTTAE6A-2, LTTE3EZ-1 and LTTAE6A-2 ), and a primer pair is designed based on the two groups of molecular markers, and it is found through verification that the designed primer pair can be used for identifying the genotype of a salt-tolerant wheat-tetraploid long-spike Aegilops tauschii 3EL translocation line, that is, whether the tetraploid long-spike Aegilops tauschii salt-tolerant 3EL chromosome is homozygous or not can be identified. The application provides an important way for wheat tribe system evolution, germplasm resource identification and molecular marker assisted selection breeding.
