While ancestral tetraploid wheats were predominantly spring-types with single VRN-A1 gene copies, later mutations in common wheat created winter varieties through altered gene copy numbers and enhanced cold tolerance. An intriguing revelation links regional food preferences to wheat genetics.Grain hardness, controlled by Pina and Pinb genes, determines culinary uses. Mutations in either gene produce harder grains ideal for baked goods, while intact genes yield softer wheat preferred for steamed buns. “This explains why northern China’s wheaten food culture favors hard wheat, while southern regions lean toward softer varieties,” Zhang explained. Liu Xu, an Academician with the Chinese Academy of Engineering, noted the research marks china’s entry into the big-data era of wheat germplasm studies, accelerating the discovery of vital agricultural genes.
Unveiling Wheat’s Secrets: how Genomics Is Shaping China’s harvest

Recent groundbreaking research in China is revolutionizing our understanding of wheat, revealing the genetic basis for its adaptation to diverse environments and its role in shaping regional culinary traditions. In this interview, Dr. Mei Zhang, a leading expert in wheat genomics, discusses these fascinating findings and their implications for agriculture in the future.
wheat Genomes: Progress and Challenges
Senior Editor:
dr. Zhang, recent studies have made meaningful strides in mapping the wheat genome. Can you tell us about the progress made and the challenges that remain?
Dr. zhang:
yes, there has been remarkable progress. We now have near-complete assemblies of several wheat genomes, including the Chuanmai 104 genome, which stands out for its high quality. Though, even with these advancements, there are still thousands of gaps in published wheat genomes. The complexity of the wheat genome, with its multiple sets of chromosomes, makes this a challenging task.
Chinese Spring: A Crucial Cultivar
Senior Editor:
What is the significance of the Chinese Spring cultivar in wheat research?
Dr. Zhang:
Chinese Spring, or CS, is a landrace from China that has been instrumental in genetic studies of wheat worldwide. It’s a very valuable resource for researchers due to its well-characterized genetic makeup and its susceptibility to various diseases.
Wheat Evolution and Food Culture
Senior Editor:
How has this research connected wheat genetics to regional food cultures?
Dr. Zhang:
That’s one of the most fascinating findings! the hardness of wheat grains, controlled by genes called Pina and Pinb, determines its culinary uses. Northern China, for instance, favors hard wheat, ideal for baking, while southern regions prefer softer wheat for steamed buns. This genetic variation aligns perfectly with regional food traditions.
Deciphering Winter and Spring Wheat
Senior Editor:
The research shed light on the evolution of winter and spring wheat varieties. Could you elaborate on that?
Dr. zhang:
It turns out that ancestral tetraploid wheats were primarily spring-type, with a single copy of the VRN-A1 gene. Later, mutations in common wheat led to the development of winter wheat. These mutations involve changes in gene copy number and enhanced cold tolerance.
Big Data and the Future of Wheat Breeding
Senior Editor:
What are the implications of this research for the future of wheat breeding?
Dr. Zhang:
This research marks a significant step forward for wheat breeding. By understanding the genetic basis of crucial traits like grain hardness and cold tolerance, we can develop more resilient and adaptable wheat varieties. It also paves the way for more efficient breeding practices using big data analysis and genomic selection.
This groundbreaking research is yielding remarkable insights into the genetics of wheat, its adaptation to diverse environments, and its connection to food culture. By unlocking these secrets, scientists are paving the way for a more lasting and resilient future for global food security.
