Spore germination and gametophore development of mosses in response to competition
<p class="MsoNormal"><span>Interactions between moss species in their earliest growth stages have received little attention. To what extent interspecific competition or priority effects influence spore germination, protonemal development, and gametophore emergence is unknown. We evaluated such effects in pairwise interaction between six common bryophyte species: <em>Atrichum undulatum, Bryum argenteum, Ceratodon purpureus, Funaria hygrometrica, Hypnum cupressiforme,</em> and <em>Leptobryum pyriforme</em>. </span><span>Interspecific interactions were assessed in vitro. Spores were sterilized and sown on agar plates in three treatments: 1) as single species cultures (controls), 2) as pairwise species cultures inoculated simultaneously, and 3) with a time lag of 20 days between species. Data on time needed for spore germination, germination rate, the time needed for gametophore differentiation, number of gametophores per germinated spore and average diameter of colonies were collected. We also performed spore germination tests in single-species cultures at the start and end of the study, as well as tests for density-dependency at spore germination and gametophore formation. </span></p>
Data from: Frequent allopolyploidy with distant progenitors in the moss genera Physcomitrium and Entosthodon (Funariaceae) identified via subgenome phasing of targeted nuclear genes
<p>Polyploids represent a new frontier in species discovery among embryophytes. Within mosses, polyploid discovery is challenged by low morphological complexity. The rapid expansion of sub-genome sequencing approaches in addition to computational approaches to identifying whole genome duplication using allelic variation among nuclear markers has allowed for increased polyploid discovery among mosses. We confirm the intergeneric hybrid nature of <em>E. hungaricus</em>, and the allopolyploid origin of <em>P. eurystomum </em>and of one population of <em>P. collenchymatum</em>. We also reveal that hybridization gave rise to <em>P. immersum, </em>as well as to yet unrecognized lineages sharing the phenotype of <em>P. pyriforme</em>,<em> P. sphaericum</em> and <em>P. collenchymatum. </em>Our findings and methods demonstrate the utility of a novel approach to allele phasing and subgenome assignment, called homologizer, when working with polyploid genomes, and its value in identifying progenitor species using target capture data.</p>
