Genome-Wide Analysis Identified a Set of Conserved lncRNAs Associated with Domestication-Related Traits in Rice

Crop domestication, which gives rise to a number of desirable agronomic traits, represents a typical model system of plant evolution. Numerous genomic evidence has proven that noncoding RNAs such as microRNAs and phasiRNAs, as well as protein-coding genes, are selected during crop domestication. However, limited data shows plant long noncoding RNAs (lncRNAs) are also involved in this biological process. In this study, we performed strand-specific RNA sequencing of cultivated rice Oryza sativa ssp. japonica and O. sativa ssp. indica, and their wild progenitor O. rufipogon. We identified a total of 8528 lncRNAs, including 4072 lncRNAs in O. rufipogon, 2091 lncRNAs in japonica rice, and 2365 lncRNAs in indica rice. The lncRNAs expressed in wild rice were revealed to be shorter in length and had fewer exon numbers when compared with lncRNAs from cultivated rice. We also identified a number of conserved lncRNAs in the wild and cultivated rice. The functional study demonstrated that several of these conserved lncRNAs are associated with domestication-related traits in rice. Our findings revealed the feature and conservation of lncRNAs during rice domestication and will further promote functional studies of lncRNAs in rice.     

基于功能语境视角下的非物质文化遗产外宣归化异化翻译——以扬州大运河外宣翻译为例

非物质文化遗产的外宣翻译和国家当前提出的"文化走出去战略"不谋而合。归化异化翻译理论更适合于翻译中文化因素的处理已得到了翻译界的认可。文章以扬州大运河非物质文化遗产外宣翻译为研究对象,针对非遗外宣翻译的目的及特点,以功能语境理论为指导方针,以归化异化翻译为手段,来探讨非物质文化遗产的外宣翻译。     

归化与异化之融合

翻译中跨文化因素是令译者感到棘手的一个问题.从归化与异化的内涵出发,针对当前对待归化与异化翻译法中出现一些偏激现象,以翻译实例为论证,提出应将归化与异化结合起来灵活使用,从而解决跨文化因素的翻译困难.     

翻译中的"异国情调"--兼谈鲁迅翻译理论的现实意义

从文化与翻译的关系入手,论述处理文本中文化内涵的两种方法,即:归化策略和异化策略。指出从文化传真的目标看,翻译应有“异国情调”。     

归化与异化--翻译策略原则的选择及其度的把握

关于“归化与异化”的问题,是翻译界争论的焦点之一。翻译策略的选择与目的语文化地位、译者的文化态度、翻译的目的、文本类型、功能、读者群等因素有直接关系。“归化”与“异化”各有其长,二者在翻译中应相辅相成、互相补充。所以,对“归化”与“异化”的运用,应把握好“度”的问题。     

Reduced acetaldehyde production by genome shuffling of an industrial brewing yeast strain

High levels of acetaldehyde produced by yeast during fermentation can be of concern to product quality. A novel approach, based on genome shuffling, was applied to reduce the production of acetaldehyde by industrial brewing strain YS86. Four isolates with different impacts of acetaldehyde concentration were obtained from populations generated by ultraviolet irradiation and nitrosoguanidine mutagenesis. These yeast strains were then subjected to recursive pool‐wise protoplast fusion. A strain library that was likely to yield positive colonies was created by fusing the lethal protoplasts obtained from both UV irradiation and heat treatments. After two rounds of genome shuffling, a recombinant YSF2–9 strain produced less acetaldehyde than wild‐type strain YS86, by 64.5 and 66.2% in laboratory and pilot plant fermentations, respectively. The shuffled yeast strain YSF2–9 was genetically stable and may have a potential application in brewing industry for managing acetaldehyde in beer.
