“…They have a worldwide distribution in moist temperate and tropical habitats as pioneer colonizers of nutrient-poor substrates. Having thalloid gametophytes and persistent sporophytes, hornworts are key to understanding the transformation from the gametophyte-dominated life cycles of non-vascular plants to the sporophyte-dominated life cycles of vascular plants [7].…”

Fungal symbioses in hornworts: a chequered history

et al. 2013

Hornworts are considered the sister group to vascular plants, but their fungal associations remain largely unexplored. The ancestral symbiotic condition for all plants is, nonetheless, widely assumed to be arbuscular mycorrhizal with Glomeromycota fungi. Owing to a recent report of other fungi in some non-vascular plants, here we investigate the fungi associated with diverse hornworts worldwide, using electron microscopy and molecular phylogenetics. We found that both Glomeromycota and Mucoromycotina fungi can form symbioses with most hornworts, often simultaneously. This discovery indicates that ancient terrestrial plants relied on a wider and more versatile symbiotic repertoire than previously thought, and it highlights the so far unappreciated ecological and evolutionary role of Mucoromycotina fungi.

“…Despite their low species numbers, hornworts represent a key group for understanding the evolution of plant form because current phylogenies place them as sister to tracheophytes (Qiu et al 2006). Villarreal et al (2010) fill some important gaps in hornwort biology and biodiversity, providing estimates of hornwort species richness worldwide and identifying centers of diversity. The paper also includes some stunning plates illustrating the morphology and ultrastructure of this enigmatic group of plants.…”

“…Following angiosperms, they are the most diverse group of plants in the world: ~ 5,000 species of liverworts, 13,000 species of mosses and 150 species of hornworts (Crandall-Stotler et al, 2009;Goffinet et al, 2009;Renzaglia et al, 2009).

Bryophytes (liverworts, mosses and hornworts) are the closest living relatives of the first group of plants that successfully colonized land. This small but well-established group of plants is unique among other land plants in having a dominant gametophyte phase in their life cycle and a single unbranched sporophyte that depends on the dominant gametophyte plant. Bryophytes occur throughout the world in all continents, occupying an assortment of habitats, especially in moist shady places. Many species have broad geographic ranges that may span two or more continents. Dispersal of bryophytes is brought about by spores, vegetative propagules or by unspecialized fragments of the gametophyte.The bryophyte flora of Sri Lanka remains relatively poorly researched. According to checklists available, the Island harbours 560 mosses, 327 liverworts and five hornworts. Most of the collecting has been in the southern half of the country, especially in the Central Highlands. Exact locality details are missing for most of these specimens. There is no documentation for moss or liverwort Flora of Sri Lanka. Lack of a thorough taxonomic foundation is a major impediment to study the biogeography of Sri Lankan bryophytes. O'Shea (2003) presented a summary of current knowledge of biogeography of Sri Lankan mosses. According to his statistical analysis based on existing records Sri Lankan mosses show strong relationships with India, Indochina, and Malaysia but a much lower affinity with Africa.Here we conducted a similar study for liverworts and hornworts using Kroeber's percentage of similarity, which suggests that Sri Lankan liverworts and hornworts show a considerable similarity with those of Java, Malaysia, Thailand, and India. However, more and wider systematic field explorations and taxonomic studies are needed to understand the biogeography of Sri Lankan bryophytes. To address this, field explorations and phylogenetic studies are being carried out, and the results will contribute to elucidate the biogeographic affinities of Sri Lanka's bryophyte flora.
