种子大小是影响农作物产量的主要因素之一，提高种子产量对改善人类生活水平具有重要作用。研究控制种子大小的重要基因，并寻找高产相关的功能基因，对作物高产育种具有重要的理论意义和应用价值。目前，通过基因失活或超量表达分析，已经发现了一些控制种子大小的功能基因。这些功能基因参与胚、胚乳、珠被的发育过程，通过调控细胞的增殖和伸长程度控制种子的大小。本文主要综述现已鉴定的控制种子大小的一些重要基因。

 As a novel type of oil crop in China, tigernut (Cyperus esculentus L.) is planted for its wide adapta⁃
tion, high yield and high oil content in tuber. To investigate genetic basis and to facilitate breeding and molecular bi⁃
ology research, a high quality full-length transcriptome was constructed based on single-molecule real-time
(SMRT) sequencing. The library was derived from mixed sample of tuber, stolon, root, shoot apex, blade, sheath,
flower, and floral axis. After filtering, a total of 23.20 Gb high quality data was obtained, and 319 568 circular con⁃
sensus sequences with an average of 2101 bp and full passes of 43 were extracted. Finally, 57 849 high quality tran⁃
scripts, composing 121.79 Mb, were obtained after clustering, polishing and redundancy removing. The complete⁃
ness of this transcriptome library was established to be 79.58%. And approximately 76.20% of the total transcripts
are full-length. The BLAST search against 7 main databases including NR, Swissprot, GO, KOG, eggNOG, Pfam,
and KEGG resulted in annotation of 52 424 transcripts, amounting for about 90.62% of the total transcripts. Addi⁃
tionally, the analyses also resulted in annotation of 3759 lncRNA, 43 060 SSR, and 2300 transcription factor-encod⁃
ing sequences. These results improved knowledges on genetic information of tigernut, and provided valuable re⁃
source for futher expression profiling and utilization of functional genes.

Introduction of double—stranded RNA(dsRNA)into cells can induce specific mRNA degradation，This process is called RNA interference(RNAi)．During the past 10 years, tremendous progress has been made in revealing the underlying mechanism of RNAi and related silencing responses. RNAi has become a powerful research tool in regulating the expression of target genes for expected or desirable phenotypes． In this article，the mechanism of RNAi has been described and summarized，and the application of RANi in plant functional genomics has also been reviewed。

To explore the MOE (margin of exposure) application in risk assessment of peanut aflatoxins in consumers, data of aflatoxins contamination in post-harvest peanut of China and the data of Chinese peanut consumption were collected. Based on aflatoxins toxicological data, MOE values of different regions from population of different age-groups were evaluated. Results indicated no significant difference between urban and rural regions, but children were at higher risk than other populations. Compared to low-dose extrapolation, MOE was recommended due to its effective performance in posterior analysis.

The volatile compounds in both cold-﹠hot-pressed flaxseed oil samples were extracted using headspace solid phase micro-extraction (HS-SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that main volatile compositions in cold-pressed flavor flaxseed oil were 1-hexanol, 2-butanol, 2-methyl-1-Butanol，1-pentanol, hexanal, 4-hydroxy-butanoic acid，2-ethyl-furan, and the total relative content of alcohols could reach up to 66%. By contrast, the relative content of alcohols in hot-pressed flaxseed oil volatile compounds dropped quickly, and the characteristic volatile compounds were found to be a lot of Maillard reaction products, such as furfurals, pyrazines, pyrroles , pyridines and so on, the relative content of aldehydes (140 ℃, 25.1%) and heterocyclic compounds (140 ℃, 41.68%) increased rapidly. The Maillard reaction Products formed hot-pressed flaxseed oil unique toasting flavor. But according to research these aromatic heterocyclic compounds and their complexes have toxic effects on human physiological function, thus affects the safety of hot-pressed linseed oil, by comparison, cold-pressed linseed oil has the characteristics of higher food safety.
