A new member of the Lea B19 gene family from barley, termed B19.1b, has been isolated and characterized. The coding region of B19.1b is highly similar to the other members of the B19 family (Espelund et al., Plant J 2 (1992) 241-252) and contains only one copy of the hydrophilic sequence found as a repeat in two other B19 genes. Like the other B19 genes, B19.1b is only expressed in embryos. The transcript appears during development at 25 days after anthesis and remains at a high level throughout embryogenesis. In immature embryos the B19.1b mRNA can be induced by abscisic acid, salt and mannitol.
已从大麦中分离并鉴定出Lea B19基因家族的一个新成员，命名为B19.1b。B19.1b的编码区与B19家族的其他成员高度相似（埃斯佩伦德等人，《植物杂志》2 (1992) 241 - 252），并且仅包含在其他两个B19基因中作为重复序列发现的亲水性序列的一个拷贝。与其他B19基因一样，B19.1b仅在胚胎中表达。转录本在开花后25天的发育过程中出现，并在整个胚胎发生过程中保持高水平。在未成熟胚中，B19.1b mRNA可被脱落酸、盐和甘露醇诱导。
