In May 2025, scientists have created the first 'pangenome' of which crop, an important staple food in Asia?
Rice
A genome is the complete set of DNA of a single individual, but any one reference genome captures only a fraction of the genetic diversity that exists across an entire species.
A pangenome, by contrast, is built by sequencing and combining the genomes of many different varieties, so it records both the 'core' genes shared by all and the 'variable' genes present in only some lines.
In May 2025 scientists reported the first pangenome of rice, assembled from a large panel of cultivated and wild rice varieties grown across Asia.
Rice is the primary staple for a very large share of the Asian population, so a fuller map of its gene pool has direct value for food security in the region.
The pangenome reveals hidden genetic variation that a single reference misses, helping breeders select genes for higher yield, drought and flood tolerance, and disease resistance.
Maize, barley and wheat are all major cereals and each has its own genomic research, but the specific 'first pangenome' milestone reported here was for rice, not for them.
Hence the correct answer is Rice.
