A novel anther-specific chalcone synthase-like gene, TaCHSL1, was isolated and characterized. The TaCHSL1 transcript was detected only within the tapetum during the “free” and early vacuolated microspore stages in both wheat and triticale. Sequence analysis indicated that the 41.8 kDa TaCHSL1 deduced protein belongs to a small distinct group of type III polyketide synthases that includes angiosperm and gymnosperm orthologs shown to be anther-specific. TaCHSL1 sequence characteristics and conservation, as well as its restricted expression pattern, point to a distinct and important biochemical role in developing anthers.
