这篇文章试图定义面向对象的数据库系统。它描述了作为一个合格的面向对象的数据库系统所应具备的主要性质和特征。我们把这些特性分成了三组: ·必备的:被称作面向对象的数据库系统所必须满足的特性。它们是复杂对象,对象标识,封装性,类型或类,继承性,结合滞后联编的复载,可扩充性,计算完备性,持久性,辅存管理,并发性,恢复和即席查询功能。·可选的:为了使系统更完善可添加的而非必备的特性。它们是多重继承性,类型检查和推理,分布,设计事务处理和版本。·开放的:设计人员可以选择的特性。它们是程序设计范例,表示系统,类型系统及一致性。我们的立场是,不祇望上述看法成为一个里程碑,以便为进一步的讨论指明方向。

Identification of QTL and underlying genes for root system architecture associated with nitrate nutrition in hexaploid wheat

The root system architecture(RSA) of a crop has a profound effect on the uptake of nutrients and consequently the potential yield. However, little is known about the genetic basis of RSA and resource adaptive responses in wheat(Triticum aestivum L.). Here, a high-throughput germination paper-based plant phenotyping system was used to identify seedling traits in a wheat doubled haploid mapping population, Savannah×Rialto. Significant genotypic and nitrate-N treatment variation was found across the population for seedling traits with distinct trait grouping for root size-related traits and root distribution-related traits. Quantitative trait locus(QTL) analysis identified a total of 59 seedling trait QTLs. Across two nitrate treatments, 27 root QTLs were specific to the nitrate treatment. Transcriptomic analyses for one of the QTLs on chromosome 2 D, which was found under low nitrate conditions, revealed gene enrichment in N-related biological processes and 28 differentially expressed genes with possible involvement in a root angle response. Together, these findings provide genetic insight into root system architecture and plant adaptive responses to nitrate, as well as targets that could help improve N capture in wheat.
