Evaluation of a Commercial Enzyme Linked Immunosorbent Assay (ELISA) for the Determination of the Neurotoxin BMAA in Surface Waters [PDF]

open access: yes, 2013
The neurotoxin ß-N-methylamino-L-alanine (BMAA) is suspected to play a role in Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis. Because BMAA seems to be produced by cyanobacteria, surface waters are screened for BMAA.

Creation of a Pseudotsuga menziesii nucellus cell suspension culture system to produce proteins involved in reproduction [PDF]

open access: yesAppl Plant Sci
Abstract Premise Cell suspension cultures of Douglas‐fir (Pseudotsuga menziesii) nucellus were created to overcome phenological limitations to the in situ study of bioactive proteins within and secreted by nucellar cells. Methods Proteins isolated from the cell suspension culture medium were analyzed using mass spectrometry, as were Douglas‐fir post ...

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

open access: yesPLoS 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]

open access: yes, 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]

open access: yes, 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.

Biflavonoids from Cycas beddomei

open access: yesChemical 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)

open access: yesChemistry & 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 ...

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

open access: yesFrontiers 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 ...

Differences in lipid homeostasis and membrane lipid unsaturation confer differential tolerance to low temperatures in two Cycas species

open access: yesBMC Plant Biology, 2021
Background C. panzhihuaensis is more tolerant to freezing than C. bifida but the mechanisms underlying the different freezing tolerance are unclear. Photosynthesis is one of the most temperature-sensitive processes.
