lycophytes vs monilophytes
Nat Rev Mol Cell Bio 8:655665, DeMaggio AE, Wetmore RH, Hannaford JE, Stetler DA, Raghavan V (1971) Ferns as a model system for studying polyploidy and gene dosage effects. Plant Mol Biol 33:1121, Article American Journal of Botany All images and text Here we describe morphological traits of living lycophytes and their extinct relatives, consider the molecular underpinnings of trait evolution and discuss future research required in lycophytes to understand the key evolutionary innovations enabling the growth and development of all vascular plants. How was apical growth regulated in the ancestral land plant? These final stages in development usually occur on the soil after the megaspore with the enclosed female gametophyte is shed from the megasporangium. The evolution of root hairs and rhizoids - PubMed Just as with bryophytes and spermatophytes (seed plants), the life cycle of pteridophytes involves alternation of generations. Using flow cytometry, genome size and degree of endopolyploidy were estimated for 37 . [5] When broadly circumscribed, the lycophytes represent a line of evolution distinct from that leading to all other vascular plants, the euphyllophytes, such as ferns, gymnosperms and flowering plants. In fact the alternative name Filicopsida was already in use. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina.

Three lycophyte orders are recognized: the club mosses (Lycopodiales), the quillworts and their allies (Isoetales), and the spike mosses (Selaginellales). lycophyte, (class Lycopodiopsida), class of spore-bearing vascular plants comprising more than 1,200 extant species. Most ferns have branching roots and form large compound leaves, or fronds, that perform photosynthesis and carry the reproductive organs of the plant. In land plants, genetic resources are well established in model species representing lineages including bryophytes (mosses, liverworts, and hornworts), monilophytes (ferns and allies), and seed plants (gymnosperms and flowering plants), but few resources are available for lycophytes (club mosses, spike mosses, and quillworts).
