Nothia aphylla
WebFeb 1, 2007 · Nothia aphylla is a small sporophyte with possible affinities in the Zosterophyllophyta. The plant consists of an aerial system of dichotomously branching orthotropic axes that arise from prostrate rhizomatous axes ( Fig. 1a–c ). Like most of the Rhynie chert land plants, an entire N. aphylla plant was < 20 cm tall. WebIn this view, the "zosterophylls" comprise a paraphyletic group, ranging from forms like Hicklingia, which had bare stems, to forms like Sawdonia and Nothia, whose stems are covered with unvascularized spines or enations. The genus Renalia illustrates the problems in classifying early land plants.

WebRhizomatous and upright axes of Nothia aphylla, another land plant from the Rhynie chert, host a glomeromycotan fungus that closely resembles G. rhyniensis. Glomites rhyniensis is an intercellular endophyte, however, that becomes intracellular only within a well-defined region of the cortex where it forms arbuscules.
Nothia was a genus of Early Devonian vascular plants whose fossils were found in the Rhynie chert in Scotland. It had branching horizontal underground stems (rhizomes) and leafless aerial stems (axes) bearing lateral and terminal spore-forming organs (sporangia). Its aerial stems were covered with small 'bumps' (emergences), each bearing a stoma. It is one of the best described early land plants. Its classification remains uncertain, although it has been treated as a zosteroph… WebA different mode of colonization probably occurred in Nothia aphylla. Fungal infection was initially intracellular in rhizoids and tissues of the rhizoidal ridge and later became intercellular in the cortex of both prostate and proximal portions of the aerial axes. Intercellular vesicles and spores were produced, ...
