FERNS AND FERN ALLIES OF IRAN
The pteridophyte account of Flora Iranica (ed. K.H. Rechinger) is still not published. The Caspian forests provide suitable habitats for the growth of many ferns and fern allies in Iran. In semi-arid and mountainous areas of Iran, mesophilous plants are restricted to rock crevices, waterfall proximity, stream banks and lake shores. Based on field collections and study of herbarium specimens in ...
متن کاملRecent Taxonomic Changes for Oregon Ferns and Fern Allies
Readers of Kalmiopsis were recently treated to a synopsis of taxonomic changes affecting flowering plants in Oregon (Chambers, 1992). The present article has been written to update readers on nomenclatural changes recently proposed for the seedless vascular plants, which include not only ferns, but also horsetails, club-mosses, and their relatives. Together these groups are often referred to as...
متن کاملArbuscular mycorrhizal fungi and dark septate fungi in plants associated with aquatic environments
Th ere have been several reports of symbionts in the roots of plants that live in aquatic environments. Arbuscular mycorrhizal fungi (AMF) are the most common microsymbionts and possibly recolonized the aquatic environment together with plants; however, their functions and the extent of their benefi ts are unclear. Furthermore, the presence of other groups of fungi, such as dark septate fungi (...

متن کاملMolecular Cloning and Characterization of Fe-Superoxide Dismutase (Fe-SOD) from the Fern Ceratopteris thalictroides
Ferns are, evolutionarily, in a pivotal position between bryophytes and seed plants (Pryer et al., 2001). Fern gametophytes, like bryophytes, have no vascular system and live on substrate surfaces as small individual plants. However, fern sporophytes do have a vascular system enabling more vertical growth than the gametophytes, and resulting in a larger herbaceous plant form. The origins of pla...
