Summary The function of a 1.1-kb transcript of WAG, a wheat AGAMOUS homolog, has not been clarified. To analyze its function, it was fused with the cauliflower mosaic virus 35S promoter and introduced into torenia (Torenia fournieri). Torenia transformants grew normally with regular plant height, size and shape of leaves, and development of inflorescence. However, the corolla was significantly smaller in 10 transformants out of 21. Generally, the vertical and horizontal diameters of the lip part of the corolla, as well as the length of the corolla (including the tube part), were all reduced in the smaller flowers, suggesting that the size of the corolla was reduced equally in all dimensions. Southern blot analysis showed the existence of the WAG gene in the genomes of these plants. We report that WAG reduces the size of the corolla in torenia.
