A group of researchers from the John Innes Centre in the United Kingdom has discovered the gene that controls the shape and size of wheat spikelets. The researchers revealed that a gene called TEOSINTE BRANCHED1 (TB1) regulates wheat floral architecture, promoting paired spikelets.
The study focused on the genetics behind a specific mutant trait in bread wheat known as paired spikelets, where a wheat inflorescence is formed of two spikelets instead of the usual one. This trait, which bears resemblance to flower production in corn and rice, is a variation that could lead to increase in yield.
