This paper describes the distribution of highly polymorphic GATA- and GACA-containing DNA regions in tomato. To study the distribution of these polymorphic regions, a mapping experiment was done. The segregation of 32 GATA- and GACA-containing loci was analyzed in a F2 population from a cross between Lycopersicon esculentum and L. pennellii. From these loci, 28 could be mapped to 8 of the 12 tomato chromosomes. Both the GATA- and GACA-containing loci seem to cluster in the same chromosomal regions. To our knowledge, this is the first report on mapping of GATA- and GACA-containing loci in plants.
本文描述了番茄中高度多态的含GATA和GACA的DNA区域的分布。为了研究这些多态区域的分布，进行了一项定位实验。在番茄（Lycopersicon esculentum）和潘那利番茄（L. pennellii）杂交产生的F2群体中，分析了32个含GATA和GACA的位点的分离情况。从这些位点中，有28个可以定位到12条番茄染色体中的8条上。含GATA和含GACA的位点似乎都聚集在相同的染色体区域。据我们所知，这是关于植物中含GATA和GACA位点定位的首次报道。
