摘要

对大量空气样本的分析表明,休眠的、有活力的真菌孢子大量存在,这表明空气传播对真菌很重要。虽然大多数孢子可能只传播很短的距离,但有迹象表明,有相当数量的孢子可以传播很远的距离。调和是伍德豪斯(1935)创造的一个术语,描述花粉的自然折叠,以适应控制和可逆的水分损失。在这里,我们讨论的证据表明,这一概念也可能适用于空气传播的真菌孢子,它们面临着类似的挑战,必须在干旱和低温时期存活下来,同时在合适的潮湿基质上沉积后保持发芽的活力。事实上,(空气)干燥的分生孢子,看起来塌陷,比液体中的孢子存活的时间长得多,而液体中的孢子会随着时间的推移而变质。这表明,对于某些类型的真菌孢子,真正的休眠是在干燥状态下达到的。对于这些通过空气传播的孢子来说,这可能被认为是一种预适应,它支持活细胞通过空气进行远距离运输。我们指出,如果湿度足够低,孢子在空气中运输时自然折叠。我们假设这是一种支持空气传播孢子释放、扩散和存活的预适应。此外,干燥的自然折叠孢子的较小尺寸也可能是相关的,例如,对于机会致病性真菌烟曲霉,较小的孢子尺寸支持肺肺泡内的沉积。

期刊介绍: Fungal Biology Reviews is an international reviews journal, owned by the British Mycological Society. Its objective is to provide a forum for high quality review articles within fungal biology. It covers all fields of fungal biology, whether fundamental or applied, including fungal diversity, ecology, evolution, physiology and ecophysiology, biochemistry, genetics and molecular biology, cell biology, interactions (symbiosis, pathogenesis etc), environmental aspects, biotechnology and taxonomy. It considers aspects of all organisms historically or recently recognized as fungi, including lichen-fungi, microsporidia, oomycetes, slime moulds, stramenopiles, and yeasts.
