Dynamic QTL Analysis of Rice Protein Content and Protein Index Using Recombinant Inbred Lines
Leina Zheng,Wenwei Zhang,Xingang Chen,Jing Ma,Weiwei Chen,Zhigang Zhao,Huqu Zhai,Jianmin Wan 한국식물학회 2011 Journal of Plant Biology Vol.54 No.5
Protein content (PC) and protein index (PI) play important roles in determining nutritional quality in rice (Oryza sativa L.). We used 71 lines derived from “Asominori/IR24” to analyze the developmental behavior of PC and PI through unconditional and conditional QTL mapping methods. In all, 10 unconditional QTLs and 6conditional QTLs for PC, and 11 unconditional QTLs and 9conditional QTLs for PI, were identified at four stages of grain filling. More were identified in the first three stages than at the final stage. Temporal patterns of gene expression for PC and PI differed over time, with several QTLs being expressed across two or three stages but many being expressed at only one stage. Some of these QTLs were closely linked with maturity QTLs reported previously. Many QTLs for PC and PI were co-localized, supporting the significant correlation found between PC and PI. Our results suggest that dynamic QTL mapping might be a valid means for revealing more genetic information about protein accumulations during seed development.

Key Technology Development and Application of High-Security UHF RFID Systems
Pan Tiejun,Zheng Leina,Wang Ming,Zhu Xiaodong 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.10
Threats in Internet of things are ubiquitous such as counterfeiting, product piracy and product recall. China is no exception to this trend. The reader SoC (system on chip) chip of Ultra high frequency (UHF) Radio Frequency Identification is the key technology to solve these threats. Due to RF technology, tag data is read and written through wireless transmission directly in the air. In order to avoid tag theft and related backstage database attack, we provide UHF High Security System (UHS-HSS) to prevent the tag data monitoring in third party equipment. UHF-HSS regard UHF RFID reader SoC chip technology as the technology foundation provides chip level security solutions, system level information security service and industry level security applications for the IOT. This paper introduces a complete set of software platforms based on UHF RFID sensors including the underlying Linux operating system and related device driver, IOT platform technology, RFID middle-ware technology and software platform application. It solves the critical problem of security and reliability of UHF RFID applications for the national economy, which is of a great significance for the development of China's Internet of Things technology.
