极端高温和持续中等高温对小菜蛾耐热性的影响

气候变化频率的增加和持续时间的延长,导致具有较短生活史的大部分农业害虫的某一个或某几个生命阶段都可经历热浪的胁迫。热浪对小型昆虫的生态学效应取决于不同生命阶段的耐热性,因而解析特定龄期下昆虫生命阶段的耐热性对理解气候变暖热浪频发的生态学影响具有重要意义。本研究以世界重要蔬菜害虫小菜蛾为研究对象,试验了小菜蛾4龄幼虫、成虫的基底耐热性和诱导耐热性,以及1龄幼虫和3龄幼虫置于不同高温[(31±1)、33±1)、35±1)℃]和暴露时间(3、6、9、12d)组合的持续中等高温耐热性。试验发现幼虫和成虫具有不同的基底和诱导耐热性,具有较弱基底耐热性的幼虫反而具有更强的诱导耐热性。不同生命阶段在持续数天的中等高温胁迫下具有不同的存活表现,早期生命阶段存活率较后期阶段的低,而且这种差异在较强高温下表现得尤为明显。昆虫不同阶段耐热性的差异,对种群的维持具有重要的生态学意义。大多数农业害虫田间种群具有混合年龄结构,热浪后耐热的发育阶段的存活,保证种群可以一直生存和繁衍下去。

基因编辑技术的发展及其在农业生产中的应用

对动植物和人类基因组的测序为功能基因组研究提供了基础数据。然而,核苷酸序列信息并不足以帮助我们了解特定的基因组元件的功能及其在表型形成中的作用。基因编辑技术能够在很大程度上解决这一问题,帮助人们快速获得新的基因组突变模式,从而以更便捷高效的方式进行功能基因组研究。对基因编辑的基本原理及常见的锌指核酸酶(ZFN)、转录激活因子样效应因子核酸酶(TALEN)和2013年出现的CRISPR/Cas9系统进行了回顾,讨论了基因编辑技术的应用历史,特别在农业应用方面,重点关注了CRISPR/Cas9系统在水稻基因编辑中的应用,阐述了CRISPR/Cas9在基因组编辑领域的问题和其他应用方面的困难,探讨了基因编辑工具在作物改良方面所面临的主要挑战和未来发展趋势。

The Plant Ontology Consortium and plant ontologies

The goal of the Plant Ontology Consortium is to produce structured controlled vocabularies, arranged in ontologies, that can be applied to plant-based database information even as knowledge of the biology of the relevant plant taxa (e.g. development, anatomy, morphology, genomics, proteomics) is accumulating and changing. The collaborators of the Plant Ontology Consortium (POC) represent a number of core participant database groups. The Plant Ontology Consortium is expanding the paradigm of the Gene Ontology Consortium (http://www.geneontology.org). Various trait ontologies (agronomic traits, mutant phenotypes, phenotypes, traits, and QTL) and plant ontologies (plant development, anatomy [incl. morphology]) for several taxa (Arabidopsis, maize/corn/Zea mays and rice/Oryza) are under development. The products of the Plant Ontology Consortium will be open-source.
