A drought-driven model for the evolution of obligate apomixis in ferns: evidence from pellaeids (Pteridaceae).
(American journal of botany, 2021-02-23)<h4>Premise</h4>Xeric environments impose major constraints on the fern life cycle, yet many lineages overcome these limitations by evolving apomixis. Here, we synthesize studies of apomixis in ferns and present an evidence-based ... -
DNA barcoding exposes a case of mistaken identity in the fern horticultural trade.
(Molecular ecology resources, 2010-11)Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can be useful to the horticultural community for keeping plants in the trade accurately identified. We use plastid rbcL, atpA, and trnG-R sequence ... -
Identifying multiple origins of polyploid taxa: a multilocus study of the hybrid cloak fern (Astrolepis integerrima; Pteridaceae).
(American journal of botany, 2012-11)PREMISE OF THE STUDY: Molecular studies have shown that multiple origins of polyploid taxa are the rule rather than the exception. To understand the distribution and ecology of polyploid species and the evolutionary significance ... -
Unique expression of a sporophytic character on the gametophytes of notholaenid ferns (Pteridaceae).
(American journal of botany, 2012-06)PREMISE OF THE STUDY: Not all ferns grow in moist, shaded habitats; some lineages thrive in exposed, seasonally dry environments. Notholaenids are a clade of xeric-adapted ferns commonly characterized by the presence of ...
