Arisaema urashima 的蕈蚊授粉:致死诱捕器和互生苗圃的相互作用。
大多数开花植物都与传粉昆虫进行互惠互利的互动,而 Arisaema 物种却采用了一种独特的、看似对立的策略,即囚禁传粉昆虫并使其在孢子囊中死亡。最近的研究发现,蓟马(Arisaema thunbergii)主要依赖真菌蚋(Leia ishitanii),一些个体可能在产卵后逃离雌花吐丝器。我们研究了乌拉岛亚麻(A. urashima)与其授粉真菌蚋之间的相互作用,因为乌拉岛亚麻(A. urashima)与蓟亚麻(A. thunbergii)亲缘关系密切。具体来说,我们测试了腐烂的乌拉岛矢车菊是否可作为某些传粉昆虫的产卵场所,以及这些传粉昆虫是否能逃脱看似致命的花诱捕器。我们取回了A. urashima吐丝以及困在吐丝中的成虫尸体,并对吐丝进行孵化,以观察是否有同种昆虫出现。此外,我们还在实验室条件下观察了横谷蝇的逃逸行为,其下一代成虫最常从腐烂的花盘中出现。我们的研究结果表明,Sciophila yokoyamai 几乎总是在产卵后从雌花佛焰苞中逃脱,同时将花序作为育幼室。与此相反,乌拉岛花的其他传粉昆虫,包括蝇蛆属真菌,则一直被困在佛焰苞内,直至死亡。这项研究表明,乌拉岛花的花盘既能起到致命陷阱的作用,也能起到互惠苗圃的作用,不同传粉昆虫的结果各不相同。我们的研究结果还表明,某些授粉昆虫对乌贼属植物繁殖的贡献被低估,甚至被忽视,因为有关其授粉昆虫群落的信息都是基于被困在花序内的访花昆虫。

期刊介绍: Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.

Permeability of postzygotic barriers: embryology of a partially fertile Epidendrum (Orchidaceae) hybrid. Issue Information Modulatory responses of physiological and biochemical status are related to drought tolerance levels in peanut cultivars. Reduced soil moisture drives leaf anatomical shifts more than chronically elevated temperatures in European temperate trees. Salicylic acid priming before cadmium exposure increases wheat growth but does not uniformly reverse cadmium effects on membrane glycerolipids.
