Nuclear ribosomal ITS functional paralogs resolve the phylogenetic relationships of a late-Miocene radiation cycad Cycas (Cycadaceae). [PDF]

PLoS ONE, 2015
Cycas is the most widespread and diverse genus among the ancient cycads, but the extant species could be the product of late Miocene rapid radiations.

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Cn-AMP2 from green coconut water is an anionic anticancer peptide [PDF]

, 2014
Globally, death due to cancers is likely to rise to over 20 million by 2030,which has created an urgent need for novel approaches to anticancer therapies such as the development of host defence peptides.

The Cycad Genus Cycas May Have Diversified From Indochina and Occupied Its Current Ranges Through Vicariance and Dispersal Events

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 ...

Biflavonoids from Cycas beddomei

Chemical and Pharmaceutical Bulletin, 2005
Chemical investigation on the constituents of the cones of Cycas beddomei has resulted in the isolation of a new biflavonoid, 2,3-dihydro-4'''-O-methyl amentoflavone, along with 2,3,2'',3''-tetrahydro hinokiflavone, 2,3,2'',3''-tetrahydro amentoflavone, 2,3-dihydro amentoflavone. The last two compounds were not reported earlier from this plant.

HISTOLOGY OF A XEROPHYTIC LEAFLET: CYCAS CIRCINALIS AND CYCAS REVOLUTA (CYCADACEAE)

Chemistry & Material Sciences Research Journal, 2020
Cycas, a primitive gymnosperm is currently facing extinction since the stem produces a starch like substance called sago, also called as sago palm. Cycads are xerophytic as they require scanty water even more drought tolerant. This study compares the leaflet micromorphological characters as a taxonomic tool to independently identify two Indian Cycad ...

Diversity, Phylogeny and Antagonistic Activity of Fungal Endophytes Associated with Endemic Species of Cycas (Cycadales) in China

Journal of Fungi, 2021
The culture-based approach was used to characterize the fungal endophytes associated with the coralloid roots of the endemic Cycas debaoensis and Cycas fairylakea from various population sites in China.
