The R locus in maize controls the tissue specificity of anthocyanin formation. Recombination between two different R-locus alleles with unique pigmentation domains has resulted in the generation of a nonparental allelic type that displays a third kind of tissue specificity. These novel changes in tissue specificity occurred in very low frequency (1 x 10(-5)). In light of this finding and of recent results concerning the regulation by R of the enzyme UDPG: flavonoid 3-0-glucosyltransferase, specified by the B(z) locus, a model dealing with the genetic control of tissue-specific functions in multicellular organisms is proposed.
玉米中的 R 基因座控制着花色素形成的组织特异性。具有独特色素结构域的两个不同 R 基因座等位基因之间的重组导致产生了一种非亲本等位基因类型，表现出第三种组织特异性。这些组织特异性的新变化发生的频率非常低（1x10(-5)）。鉴于这一发现以及最近关于 R 对由 B(z)基因座决定的酶 UDPG:类黄酮 3-O-葡萄糖基转移酶的调控的结果，提出了一个关于多细胞生物组织特异性功能的遗传控制的模型。
