毛柔花的花粉-雌蕊相互作用:结构和细胞学方面提供了在半干旱环境中具有超年开花的雌雄异株棕榈的生殖成功的见解。
在塞拉多(Cerrado)内,一种适应湿润生态系统“veredas”的棕榈——毛蕊花(buriti)——花粉-雌蕊相互作用的成功受到内在和环境因素的影响。它的超年开花,雌雄异株和不利的气候条件给施肥带来了挑战,因此花生物学的信息是必不可少的。本研究旨在确定柱头接受性,并阐明花粉-雌蕊关系的结构、细胞化学和超微结构方面。花在开花后(hpa)和授粉后(hpp)进行分析。用H2O2溶液进行柱头接受性试验。对雌蕊样品进行解剖、组织化学和电镜评价。柱头湿润,具乳头状,表皮下含有与维管束相连的厚壁组织。柱头接受性持续约36hpa。花粉管在2 hpp时穿过乳突,在共质体中向花柱管方向发育。乳突有松散的细胞壁,有利于分泌,并含有丰富的细胞器,包括大的过氧化物酶体。受精发生在每小时24 hpp,在此期间柱头表面没有病原体。与雌蕊表面的维管连接有利于花粉粒的萌发。雌蕊在受精前有很强的保护系统。柱头花粉管的共塑生长和雌蕊的高效分泌器官有助于快速受精。这些结构特征和分泌动态促进了布里蒂的繁殖,即使在超年开花和半干旱条件下也是如此。

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.
