研究的前提。 早期泥盆纪Rhynie硅质岩是研究早期陆地植物形态、生态学和生活史的宝贵来源,但关于Rhynie硅质岩植物形态发育的信息严重缺乏。方法论。Rhynie硅质岩的 系列岩石学薄片揭示了Rhynia Gwynne-vauganii植物轴线上由表皮细胞发育而来的无性繁殖。观察到了气孔、根状突起、顶端生长和维管组织形成的三个不同的发育阶段。 的发育模式类似于体细胞胚胎发生,体细胞胚胎发生是一种在现存植物中自然发生的无性繁殖形式,也可以在体外由体细胞植物细胞产生营养独立的植株。结论: 我们对这些繁殖体的新观察有助于更好地理解最早的陆地植物之一的组织和器官是如何形成的。它们使我们能够比较个体发育的OFR。Gwynne-vaugani与现存的陆地植物群一致,并展示了一种在数百万年的植物进化中保存下来的无性繁殖形式。
Premise of research. The Early Devonian Rhynie chert is an invaluable source for studying the morphology, ecology, and life cycles of early land plants, but information regarding morphological development in the Rhynie chert plants is sorely lacking.Methodology. Serial petrographic thin sectioning of the Rhynie chert reveals asexual propagules developing from the epidermal cells in the axes of the plantRhynia gwynne-vaughanii. Three distinct developmental stages recording the formation of stomata, rhizoids, apical growth, and vascular tissue were observed. Similar propagules are also found developing from hemispherical projections, also on the axes ofRhynia.Pivotal results. The developmental pattern resembles that seen in somatic embryogenesis, a form of asexual reproduction that occurs naturally in extant plants as well as in in vitro, producing nutritionally independent plantlets from somatic plant cells.Conclusions. Our new observations on these propagules significantly contribute to a better understanding of how the tissues and organs of one of the earliest land plants formed. They allow us to compare the ontogeny ofR. gwynne-vaughaniiwith that of extant land plant groups and demonstrate a form of asexual reproduction conserved over millions of years of plant evolution.
