New record of arbuscular mycorrhiza in Asterella chilensis (Aytoniaceae, Marchantiophyta), Patagonia, Argentina

Background and aims: The associations that are established between arbuscular mycorrhizae (AM) and bryophytes (Anthocerotophyta, Bryophyta and Marchantiophyta) play an important role in the development of this group of plants. In particular, the relationship between AM and Marchantiophyta has been s...

In particular, the relationship between AM and Marchantiophyta has been studied previously in different species and regions of the world and, among other things, it is mentioned that colonization by fungi can differ in abundance and occurrence even in species of the same genus. The objective of this study is to present and characterize for the first time the colonization of AM in Asterella chilensis (Aytoniaceae).M&M: The examined material comes from collections made in steppe environments of Patagonia, Argentine. The plants were conditioned, stained and analyzed according to specific techniques for bryophytes.Results: The mycorrhizal association in A. chilensis is described for the first time. A brief description and photographs of the characteristic structures of the AMare presented. The colonization percentage ranges from 35 to 38% and the AM corresponds to the Paris type, characterized by the presence of aseptate hyphaeforming intracellular arbusculate coils.Conclusions: The association between AM and a livewort A. chilensis, described here, provides information of this type of associations in taxa and in harsh and little known environments Introducción y Objetivos: Las asociaciones que se establecen entre micorrizas arbusculares (MA) y briofitas (Anthocerotophyta, Bryophyta y Marchantiophyta) juegan un papel importante en el desarrollo de este grupo de plantas. En particular, la relación entre MA y Marchantiophyta ha sido estudiada previamente en diferentes especies y regiones del mundo y, entre otras cosas, se menciona que la colonización por hongos puede diferir en abundancia y ocurrencia incluso en especies del mismo género. El objetivo de este estudio es presentar y caracterizar por primera vez la colonización de MA en Asterella chilensis (Aytoniaceae).M&M: El material examinado proviene de colecciones realizadas en ambientes de estepa de la Patagonia argentina. Las plantas fueron acondicionadas, teñidas y analizadas de acuerdo con técnicas específicas para briofitas.Resultados: Se describe por primera vez la asociación micorrícica en A. chilensis. Se presenta una breve descripción e ilustración de la planta y se comentan las estructuras características de las MA. El porcentaje de colonización osciló entre el 35 y el 38% y la MA corresponde al tipo Paris, caracterizado por la presencia de hifas aseptadas que forman espirales arbusculados intracelulares.Conclusiones: La asociación entre MA y una hepática, A. chilensis, descrita aquí, contribuye a brindar información sobre registros de este tipo de asociación en taxones y ambientes aún inexplorados.
