当前的实体对齐方法,虽然利用知识图谱中实体间的结构信息取得了不错的对齐效果,但是忽略了实体间包含的大量侧面信息。这些信息具有唯一性特征,可以用于增强对齐效果。分析了实体侧面信息在实体对齐中的可用性,提出了一种无监督实体对齐方法,使用渐进式策略并融合图文信息。该方法通过融合实体的字面量信息和视觉信息,来增强实体的特征表示;采用双向阈值最近邻算法,过滤掉距离度量过高的实体对;引入渐进式策略,来动态增加相似度阈值,以控制对齐实体对的生成质量和生成速度;定义分配算法,以优化渐进式策略得到的结果。为了验证提出的方法,在DBP15K数据集的ZH_EN、ja_EN、FR_EN子数据集上进行实验,并与PSR、EVA、DATTi等10种方法的结果进行了对比分析。实验结果表明,该方法在ZH_EN和ja_EN子数据集的对齐任务上,Hits@1指标分别达到了95.7%和97.4%,在FR_EN上Hits@10指标达到了99.9%,性能表现较佳。

The G-protein α subunit GhGPA positively regulates Gossypium hirsutum resistance to Verticillium dahliae via induction of SA and ja signaling pathways and ROS accumulation

The Crop Journal 2021年第4期9卷 823-833页

Verticillium wilt, a devastating disease in cotton caused by Verticillium dahliae, reduces cotton quality and yield. Heterotrimeric GTP-binding proteins, consisting of Ga, Gb, and Gc subunits, transducers of receptor signaling, function in a wide range of biological events. However, the function of Ga proteins in the regulation of defense responses in plants is largely unexplored, except for a few reports on model species. in the present study, a cotton G-protein a-subunit-encoding gene(GhGPA) was isolated from Verticillium wilt-resistant Gossypium hirsutum(upland cotton) cv. ND601. GhGPA transcription was up-regulated under V. dahliae stress, with higher expression in tolerant than in susceptible cotton *** localization revealed GhGPA to be located in the pla.ma.membrane. GhGPA shows high(85.0%) identity with Arabidopsis AT2 G26300(AtGPA1), and AtGPA1 gpa1-4 mutants displayed susceptibility to V. dahliae. Ectopic expression of GhGPA successfully restored the resistance of Arabidopsis gpa1-4 mutants to Verticillium wilt and made them more resistant than the wild type. Overexpression of GhGPA in Arabidopsis markedly increased the resistance and resulted in dramatic up-regulation of pathogenesis-related(PR) genes and increased in H2 O2 accumulation and salicylic acid(SA) and jasmonic acid(ja) contents. However, suppressing GhGPA expression via virus-induced gene silencing(ViGS)increased susceptibility to Verticillium wilt, down-regulated the expression of PR and marker genes in SA and ja signaling pathways, and reduced H2 O2 content. The contents of SA and ja in Arabidopsis gpa1-4 and ViGS cotton were lower than those in the wild type and empty-vector control. However,GhGPA-overexpressing Arabidopsis contained more SA and ja than the wild type when inoculated with V. dahliae. Thus, GhGPA plays a vital role in Verticillium wilt resistance by inducing SA and ja signaling pathways and regulating the production of reactive oxygen species. These findings

作者： Xiaodong Dai Yaguang Zhan Jiechi Zhang Piqi Zhang Zenghua Han Qingfang ma Xianghui Kong Jianing Liu Yinpeng ma College of Life Science Northeast Forestry University Microbiology institute of Heilongjiang Provincial Academy of Sciences institute of High Technology Heilongjiang Academy of Science

We evaluated the biomass and ergosterol content of Hericium erinaceus mycelium, and extracellular enzyme activities in H. erinaceus liquid culture following salicylic acid（SA） and methyl jasmonic acid（Me ja）supplementation. The optimal SA concentration was100 lmoláL-1, where the highest ergosterol content of 2.33 mgág-1was obtained following 6-day cultivation with100 lmoláL-1SA supplementation, and which was significantly higher than the unsupplemented control（p ／ 0.01）. Following 4-day supplementation with50 lmoláL-1Me ja, the highest ergosterol content obtained was 1.988 mgág-1, which was 25.8 % higher than the unsupplemented control. Our data indicate that SA and Me ja supplementation improves ergosterol content in *** mycelium.
