We describe a novel class of vicilin gene in Pisum corresponding to a precursor polypeptide of Mr 68000. The mRNA corresponding to this polypeptide accumulates during seed development in a pattern similar to that of convicilin. Hybridization and sequence analyses show that this vicilin gene class is less homologous to other Pisum vicilin gene classes than these last are to each other. Gene-copy-number estimates and decreased stringency hybridizations of the gene class described here show that the Pisum vicilin gene family is bigger and more complex than hitherto reported.
我们描述了豌豆中一种新型的豆球蛋白基因，它对应于 Mr 68000 的前体多肽。在种子发育过程中，与这种多肽相对应的 mRNA 积累模式与 convicilin 相似。杂交和序列分析表明，与其他豌豆豆球蛋白基因家族相比，这个豆球蛋白基因家族的同源性较低。基因拷贝数估计和这里描述的基因类别的降低杂交严格性表明，豌豆豆球蛋白基因家族比以前报道的更大、更复杂。
