Species delimitation of the Cycas segmentifida complex (Cycadaceae) resolved by phylogenetic and distance analyses of molecular data

Frontiers in Plant Science, 2016
The Cycas segmentifida complex consists of eight species whose distributions overlap in a narrow region in Southwest China. These eight taxa are also morphologically similar and are difficult to be distinguished.

The “fossilized” mitochondrial genome of Liriodendron tulipifera: ancestral gene content and order, ancestral editing sites, and extraordinarily low mutation rate [PDF]

, 2013
BACKGROUND: The mitochondrial genomes of flowering plants vary greatly in size, gene content, gene order, mutation rate and level of RNA editing. However, the narrow phylogenetic breadth of available genomic data has limited our ability to reconstruct ...

Illuminating Long-lived Cycas Cotyledons Reduces Sink Demands on Megagametophytes during Initial Seedling Growth

HortScience
Cycas megagametophyte resources are translocated to developing seedlings through the persistent green cotyledons. The source activities of cotyledons and megagametophytes following germination are not adequately understood. The decline in megagametophyte

An integrative taxonomic and phylogenetic approach reveals a new genus of Australasian Cycas-pollinating weevils (Coleoptera: Curculionidae: Cossoninae)

Zoological Journal of the Linnean Society
Cycas is the second-largest genus of cycads in Australia and the sole cycad genus in Papua New Guinea. In contrast to the other Australian cycads, which are mainly pollinated by weevils of the Tranes group of Molytinae, the Australian Cycas species are
