Dear Editor,The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) system has become a popular and powerful method for manipulating genomes with considerably little effort and high efficiency.It allows for the generation of targeted indels,genomic structure variations,and insertion of foreign fragments.However,increasing conces have been raised about possible off-target effects.Off-target editing might cause unwanted disruptions at regions homologous to the single guide RNA (sgRNA).For application in entomology,off-target editing poses a big conce in the direct observation of mutant phenotypes in somatic tissues,because the sequence-phenotype causation may be confounded (Xu et al.,2015).In addition,it is of particular importance for research and field application of gene drive,an approach used for controlling invasive species and disease-carrying insect vectors (Taning et al.,2017).

摘要：过去的十几年中，中国的房地产市场经历了一系列的变化，由一路上涨，到因经济危机带来的下跌，再到2009年后的持续上涨。房价的问题已经引来了全社会的关注。相关的研究也非常多。本文主要从房价影响因素方面分析这个问题，首先对影响因素理论方面进行分析，接下来用美国大学城周边房价数据进行实例分析并构造模型。 关键词：房价影响因素、大学城房价 一、引言 中国的房价在1998年到2008年这十年间是持
