Phylogenomic Inference Suggests Differential Deep Time Phylogenetic Signals from Nuclear and Organellar Genomes in Gymnosperms [PDF]
PlantsThe living gymnosperms include about 1200 species in five major groups: cycads, ginkgo, gnetophytes, Pinaceae (conifers I), and cupressophytes (conifers II).

The Systematics and Evolution of Gymnosperms with an Emphasis on a Few Problematic Taxa [PDF]
PlantsGymnosperms originated in the Middle Devonian and have experienced a long evolutionary history with pulses of speciation and extinction, which resulted in the four morphologically distinct extant groups, i.e., cycads, Ginkgo, conifers and gnetophytes ...

Luthrodes pandava Larvae Can Distinguish Cycas Leaf Quality in Cafeteria Experiments [PDF]
InsectsCycads are being endangered by several anthropogenic threats, and invasions of non-native herbivores are among those threats. Various country invasions by the cycad blue butterfly Luthrodes pandava have threatened the local horticulture cycad trade and ...

Assessing the extinction risk of Veracruz cycads [PDF]
Cambridge Prisms: ExtinctionCycads, an ancient lineage, face a higher threat of extinction than any other plant group. To address this urgent issue, a more comprehensive method for assessing extinction threat, the Conservation and Prioritization Index (CPI), is proposed and tested ...

Evolution of molecular communication in the permanent Azolla symbiosis [PDF]
New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

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
