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.     

Wickens, G.E. Economic botany: principles and practices

This book is a compendium of information on plants (and somemicro-organisms) that are, or could be, useful to humans. Someidea of its vast scope can be gained from the list of chapterheadings: Plant collecting, taxonomy and nomenclature; Environmentalconsiderations; Plant conservation; Ecophysiology and allieddisciplines; Plant breeding and propagation;     

Enhancement of rhizosphere citric acid and decrease of NO3−/NH4+ ratio by root interactions facilitate N fixation and transfer

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。
