Testing protocols to optimize DNA extraction from tough leaf tissue: A case study in Encephalartos
Applications in Plant Sciences, 2023 Premise Plants with stiff, leathery leaves pose a challenge for standard DNA extraction protocols. These tissues are recalcitrant to mechanical disruption via TissueLyser (or analogous devices) and are often high in secondary metabolites.

Enabling the study of gene function in gymnosperms: Virus-induced gene silencing in <i>Ephedra tweedieana</i>. [PDF]
Appl Plant SciAbstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Propagation of Cycad Collections from Seed
Sibbaldia, 2011 Propagation of cycads from seed can aid their conservation as it helps reduce the demand for wildcollected plants. Seed-produced plants can be used for reintroduction programmes if the parent plants are from known provenance and care is taken to avoid ...

The Plant Genome, 2021 Gymnosperms are among the most endangered groups of plant species; they include ginkgo, pines (Conifers I), cupressophytes (Conifers II), cycads, and gnetophytes. The relationships among the five extant gymnosperm groups remain equivocal. We analyzed 167

Carbohydrates, pollinators, and cycads [PDF]
Communicative & Integrative Biology, 2015 Cycad biology, ecology, and horticulture decisions are not supported by adequate research, and experiments in cycad physiology in particular have been deficient. Our recent report on free sugar content in a range of cycad taxa and tissues sets the stage for developing continued carbohydrate research. Growth and development of cycad pollen, mediation of

The complete chloroplast genome of Microcycas calocoma (Miq.) A. DC. (Zamiaceae, Cycadales) and evolution in Cycadales [PDF]
PeerJ, 2020 Cycadales is an extant group of seed plants occurring in subtropical and tropical regions comprising putatively three families and 10 genera. At least one complete plastid genome sequence has been reported for all of the 10 genera except Microcycas ...
