Plectenchyma - types and definitions

The different layers of stratified thallus of most lichens are formed from variations in the patterns of groups of hyphae that can be organized into tissue with the appearance of parenchymatous organization. This tissue type is known as plectenchyma (or pseudoparenchymatous tissue) but in lichenized...

Las distintas capas del talo estratificado de la mayoría de los líquenes se forman a partir de variaciones en los patrones de agrupación de las hifas, que pueden organizarse en tejidos con apariencia de organización parenquimatosa. Este tipo de tejido se conoce como plecténquima (o pseudoparénquima), pero en los hongos liquenizados la terminología aplicada a los subtipos de plecténquima aún no se ha estandarizado y varía de un autor a otro. Las diferencias entre las definiciones de los autores conducen a problemas conceptuales que interfieren clara y directamente en la descripción técnica de las diferentes capas anatómicas que se encuentran en los líquenes. Con la mejora de los sistemas de observación, mediante el uso de microscopía óptica y microscopía electrónica de transmisión y barrido, las observaciones morfológicas de los microcaracteres han mostrado un gran potencial de aplicabilidad taxonómica en muchos grupos de líquenes, lo que demuestra la importancia de estandarizar los términos utilizados en los estudios anatómicos. As diferentes camadas do talo estratificado da maioria dos liquens são formadas a partir de variações nos padrões de agrupamento das hifas que podem ser organizadas em tecidos com a aparência de organização parenquimática. Este tipo de tecido é conhecido como plectênquima (ou pseudoparênquima), mas em fungos liquenizados a terminologia aplicada aos subtipos de plectênquima ainda não foi padronizada e varia de autor para autor. As divergências entre as definições dos autores levam a problemas conceituais que interferem clara e diretamente na descrição técnica das diferentes camadas anatômicas existentes nos liquens. Com o aperfeiçoamento dos sistemas de observação, através da utilização de microscopia de luz e microscopia eletrônica de transmissão e varredura, as observações morfológicas dos microcaracteres têm mostrado grande potencial de aplicabilidade taxonômica em muitos grupos de liquens mostrando a importância de padronização dos termos utilizados em estudos anatômicos.
