The invention discloses an application of a tomato B3-337 transcription factor in improvement of tomato quality, a gene for coding a B3-337 transcription factor protein is named as a B3-337 gene, and the nucleotide sequence is shown as SEQ ID NO.1. The invention also discloses an application of the tomato B3-337 transcription factor in improvement of tomato quality. According to the application, a carrier pFM3100GFP-B3-337 is constructed, so that the B3-337 is proved to be positioned in a cell nucleus. A transcriptional activity detection result proves that B3-337 has transcriptional activation activity. RT-qPCR (real-time quantitative polymerase chain reaction) and GUS (glucuronidase) dyeing show that the transcription factor is expressed in pericarp, seed, placenta and center pillar of each fruit ripening stage. According to the invention, a B3-337 gene overexpression plant is obtained by constructing a B3-337 overexpression vector, and compared with a wild type, the tomato fruit overexpressed with the B3-337 gene has the advantages that the content of soluble solids brix is increased, the fruit becomes larger, and the weight becomes heavier. It is shown that the B3-337 transcription factor plays an important regulation role in positive regulation of tomato fruit quality. The invention lays a good gene genetic resource foundation for the cultivation of new varieties of high-quality tomatoes.
