Comparative proteomic analysis of the response in resistant and susceptible maize inbred lines to infection by Curvularia lunata

Proteins differentially expressed from maize leaves in response to the infection by Curvularia lunata strain CX-3 were identified through a high-resolution two-dimensional gel electrophoresis (2-DE) method. Two inbred lines, 78599-1 and E28, were used, respectively, as resistant and susceptible lines to CX-3 infection. Proteins were extracted from the fourth leaves of six- or seven-leaf stage plants sampled at 24, 36, 48, 60, and 72 h after inoculation with CX-3. Twenty-seven differentially expressed protein spots resolved on the 2-DE gels were identified by MALDI-TOF MS/MS. The results showed that these proteins are associated with photosynthesis, respiration,oxidative and drought stress tolerance as well as signal transduction in maize. Among stress-related proteins, the 22 kDa drought-inducible protein, putative glutathione peroxidase (GPX), and translation initiation factor (eIF-5A) were up-regulated in the resistant inbred line and were implicated in host defense response to C. lunata infection. It suggests that drought-inducible and oxidation stress-related proteins might directly contribute to maize resistance to C. lunata.

基于文献计量学的胡麻研究领域全景分析

胡麻是我国五大油料作物之一,是古老的韧皮纤维作物和油料作物.胡麻适宜在凉爽、湿润的气候下种植.胡麻原起源于中东、地中海沿岸.后传到中国进行种植,在中国的主要分布区为甘肃、新疆、黑龙江、吉林等省.本文以我国胡麻的研究文献为对象,对文献的年期、作者地区(省市)、作者人数、是否有通讯作者、第一作者年龄、第一作者单位、基金来源、页数、研究类型、作者合作率、合作度、论文数居前10位的机构等情况进行了统计与分析.本论文将为相关研究人员把握胡麻研究现状和为今后研究提供有益参考.
