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 ...

Ecological Isolation Maintains the Species Boundaries Between Two Sympatric <i>Cycas</i> From Southwest China. [PDF]
Ecol EvolThe study reveals that sympatric Cycas species (C. pectinata and C. simplicipinna) maintain strict species boundaries without hybridization, driven by reproductive isolation mechanisms (divergent coning times and pollinator specificity) and ecological niche differentiation (habitat preferences, soil pH differences).

The complete mitochondrial genome of Zamia integrifolia uncovers distinct patterns of genomic turnover and repeat expansion in Zamiaceae [PDF]
Front Plant SciIntroduction Gymnosperm mitochondrial genomes exhibit substantial variation in size and structure, yet the evolutionary dynamics of Cycadales remain insufficiently explored beyond the genus Cycas. Methods We assembled the complete mitochondrial genome of

Disparity of cycad leaves dispels the living fossil metaphor [PDF]
Communications BiologyThe living fossil metaphor is tightly linked with the cycads. This group of gymnosperms is supposed to be characterised by long-term morphological stasis, particularly after their peak of diversity and disparity in the Jurassic.

Ethnobotany of Mexican and northern Central American cycads (Zamiaceae) [PDF]
Journal of Ethnobiology and Ethnomedicine, 2019 Background This study documents cycad-human relationships in Mexico, Belize, Guatemala, El Salvador, and Honduras over the last 6000 years. The impetus was acute need for a better understanding of previously undocumented uses of cycads in this region ...
