A lectin gene family is located on linkage group 7 in pea. The lectin genes are arranged as a cluster, with no recombination observed within the multigene family. A lectin-like cDNA clone, pEA207, and eight DNA fragments generated by random priming also were mapped in the region of the lectin genes. None of the known pea mutants altering Rhizobium leguminosarum strain specificity map to this region of the genome, and therefore their altered specificities appear not to be directly produced by mutations in the lectin genes.
一个凝集素基因家族位于豌豆的第7连锁群上。凝集素基因排列成簇，在这个多基因家族中未观察到重组现象。一个类凝集素cDNA克隆pEA207以及通过随机引物产生的8个DNA片段也被定位在凝集素基因区域。已知的改变豌豆根瘤菌菌株特异性的豌豆突变体均未定位到基因组的这个区域，因此它们改变的特异性似乎不是由凝集素基因中的突变直接产生的。
