The National Center for Biotechnology Information (NCBI) maintains a globally recognized and authoritative genetic database. As of August 10, the database had recorded 7,538 peanut ESTs (Expressed Sequence Tags) and 479 peanut gene sequences. However, nearly 60% of these entries originated from the Shandong Academy of Agricultural Sciences in China, highlighting its significant contribution to the field.
Recently, the High-tech Research Center at the Shandong Academy of Agricultural Sciences made a major breakthrough by submitting 4,406 peanut ESTs and 270 peanut genes to the NCBI in one go. This achievement represents a key milestone in the study of peanut functional genomics and places the research among the top globally.
Genomics is one of the most advanced areas in biological research and plays a crucial role in a country’s long-term technological and economic development. Building full-length cDNA libraries, conducting large-scale sequencing, and performing functional predictions are essential for understanding gene expression and discovering new genes.
Since 2003, Bi Yuping, director of the High-tech Research Center and a doctoral supervisor, has led a team of over 10 experts from within and outside the United Nations. The team has leveraged the high-level genomics platform of the Shandong Provincial Key Laboratory of Crop and Livestock Breeds Improvement Biotechnology. Over the past three years, they successfully constructed a full-length cDNA library from immature seeds of the main cultivar "Luhua 14" and conducted extensive sequencing.
To date, more than 11,000 cDNA sequences have been sequenced, with over 5,500 of them undergoing BLAST analysis. The project has yielded 2,100 single-copy sequences and more than 600 sequence clustering results, providing valuable insights into peanut genetics.
Peanuts are vital grain, oil, and energy crops. China currently leads the world in both total peanut production and exports. In 2005, China accounted for 42% of the global peanut market. Shandong, as a leading peanut-producing province, ranks first nationally in terms of sown area, yield, total output, processing, and exports.
The Shandong Academy of Agricultural Sciences has focused on cutting-edge international research topics, conducting large-scale studies on peanut functional genomics. Their work has significantly contributed to the genetic improvement of peanuts and the development of high-yield, high-quality varieties, strengthening China's position in agricultural biotechnology.
