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 ...

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

Characterization of the complete chloroplast genome of endangered Cycads Zamia fischeri Miq. ex Lem
Mitochondrial DNA. Part B. Resources, 2018 The whole chloroplast (cp) genome sequence of Zamia fischeri has been characterized. The cp genome length was 164,767 bp in length, with a GC content of 39.7%, containing a large single copy (LSC) of 90,226 bp, a small single copy (SSC) of 23,223 bp, and

G-fibers and Florin ring-like structures in Dioon (Zamiaceae)
Botanical Sciences, 2016 Cuticle information and epidermal characters have great potential in systematic studies. However, micromorphology and anatomical studies on cycads are relatively scarce in comparison to similar studies on other gymnosperms.

Frontiers in Ecology and Evolution, 2020 Biogeographically, cycads were once widely distributed but the extant cycads are restricted to tropical and subtropical regions. They originated ∼ 300 Ma and re-diversified recently around 12 Ma, with the genus Cycas being the most rapidly diversified ...

Phylogenomics and coalescent analyses resolve extant seed plant relationships. [PDF]
PLoS ONE, 2013 The extant seed plants include more than 260,000 species that belong to five main lineages: angiosperms, conifers, cycads, Ginkgo, and gnetophytes. Despite tremendous effort using molecular data, phylogenetic relationships among these five lineages ...

Perspectives on Endosymbiosis in Coralloid Roots: Association of Cycads and Cyanobacteria
Frontiers in Microbiology, 2019 Past endosymbiotic events allowed photosynthetic organisms to flourish and evolve in terrestrial areas. The precursor of chloroplasts was an ancient photosynthetic cyanobacterium.

Frontiers in Plant Science, 2021 Coevolution between plants and insects is thought to be responsible for generating biodiversity. Extensive research has focused largely on antagonistic herbivorous relationships, but mutualistic pollination systems also likely contribute to ...
