REVIEW

Mycorrhizal relationships in lycophytes and ferns
M. Lehnert & M. Kessler pg(s) 101-116
ABSTRACT
ABSTRACT
Mycorrhizae, i.e., symbiotic associations between fungi and plant roots, occur in about 80% of land plant species and have been shown to benefit both the fungus (carbon uptake) and plant (nutrient and water uptake, protection against pathogenic fungi). We here provide a brief overview of the state of knowledge of mycorrhization in ferns. Only about 62% of species studied to date have mycorrhizae, with arbuscular mycorrhizal fungi (mainly Glomeromycta) being the dominant partners, while other associations are made with ascomycetes and the so-called Dark Septate Endophytes. There is no clear phylogenetic signal in mycorrhization among ferns, with both basal (e.g., Anemiaceae, Gleicheniaceae, Cyatheaceae) and derived families (e.g., non-grammitid Polypodiaceae, Tectariaceae, Aspleniaceae) having <50% of species mycorrhizal. Ecologically, epiphytes have lower degrees of mycorrhization than terrestrial species, with aquatic taxa almost completely lacking mycorrhizae. This probably reflects the requirements of the fungi. There are no experimental studies on the benefits of mycorrhizae for ferns, but field experiments suggest that there is a fine balance between positive and negative effects, so that many fern species have disposed of the fungi either generally or facultatively. Much remains to be learnt about mycorrhization in ferns, especially in an evolutionary context in comparison with bryophytes and seed plants.

MAIN ARTICLES

The fern family Pteridaceae in Turkey
M. Bona & M. Gibby pg(s) 119-132
ABSTRACT
The last comprehensive study of Turkish Pteridaceae was made over 50 years ago. In this study the family Pteridaceae in Turkey is reviewed according to recent taxonomic and nomenclatural changes and a full description, synonyms and distribution information are given for each taxon and a key provided.
