A 500-bp cDNA fragment was amplified via RT-PCR from drought-induced total RNA of the drought-tolerant B. crassifolia Hemsl. using primers based on the sequence of published dehydrin conserved region. By using 5’ RACE, full-length coding region (1 148 bp) of BDN1 gene was produced. It is a new member of the dehydrin gene family. Southern analysis indicated that BDN1 is present in the 6. crassifolia genome as a single-copy gene. Northern analysis revealed that its expression is inducible by drought and cold stresses as well as ABA application.

多重分派是面向对象语言的一个高级特性,是面向对象程序设计中多态性实现的基础。目前的主流面向对象语言Java与C++都不支持动态多重分派。文章介绍了Java语言现有的分派技术,讨论了为Java语言添加动态多重分派特性的几种途径并对它们的利弊进行比较。文章提出并分析了面向对象语言实现多重分派需要解决的若干问题,最后展望了未来的研究方向。
