The crane fly glycosylated triketide δ‐lactone cornicinine elicits akinete differentiation of the cyanobiont in aquatic Azolla fern symbioses

Plant, Cell &Environment, Volume 47, Issue 7, Page 2673-2690, July 2024.
Abstract The restriction of plant‐symbiont dinitrogen fixation by an insect semiochemical had not been previously described. Here we report on a glycosylated triketide δ‐lactone from Nephrotoma cornicina crane flies, cornicinine, that causes chlorosis in the floating‐fern symbioses from the genus Azolla. Only the glycosylated trans‐A form of chemically

Graphene Chainmail Shelled Dilute Ni─Cu Alloy for Selective and Robust Aqueous Phase Catalytic Hydrogenation

Advanced Science, Volume 11, Issue 13, April 3, 2024.
Dilute alloy and chainmail synergy profoundly enhances catalytic activity. Trace Ni‐doping in cost‐effective CuNi0.05 induces properly tuned lattice strain and assembles three‐layered oxygen‐doped graphene chainmail rich in defects with enhanced Schottky junction.

Highly Potent and Low‐Volume Concentration Additives for Durable Aqueous Zinc Batteries: Machine Learning‐Enabled Performance Rationalization

Advanced Materials, Volume 36, Issue 9, March 1, 2024.
1,2‐alkanediols with an optimal chain length are unveiled as highly potent low‐volume concentration electrolyte additives to address the zinc anode rechargeability for the practical development of aqueous zinc batteries. A machine learning‐based model that maps the performance relative to critical additive physicochemical descriptors is presented ...

Evolutionary and ecological trends in the Neotropical cycad genus Dioon (Zamiaceae): An example of success of evolutionary stasis

Ecological Research, Volume 39, Issue 2, Page 131-158, March 2024.
Cycads represent an example of the success of evolutionary stasis. Despite its conservative nature, the cycad genus Dioon has been able to diversify due to phylogenetic, stochastic, and environmental factors associated with the biogeography of Mexico. Abstract Cycads represent an example of the success of evolutionary stasis. Despite their early origin,

SEM observations on cyanobacteria-infected cycad coralloid roots

, 1988
In Nostoc -infected coralloid roots of the cycads Encephalartos transvenosus Stapf & Burtt Davy and E. paucidentatus Stapf & Burtt Davy the intercellular cyanobacteria are present in a narrow circular band between the outer and the inner cortex only ...

The identification of the coralloid root endophytes of the southern African cycads and the ability of the isolates to fix dinitrogen

South African Journal of Botany, 1987
Forty-one isolates of the cyanobionts in the coralloid roots of 31 cycad species, which include all the species indigenous to the Republic of South Africa, were identified. One isolate (from Encephalartos hildebrandtii) appears to be a species of Calothrix. All the other isolates were identified as species of Nostoc. Twenty-eight isolates were assigned
