Nitrogen supply and cyanide concentration influence the enrichment of nitrogen from cyanide in wheat (Triticum aestivum L.) and sorghum (Sorghum bicolor L.) [PDF]

open access: yes, 2010
Cyanide assimilation by the beta-cyanoalanine pathway produces asparagine, aspartate and ammonium, allowing cyanide to serve as alternate or supplemental source of nitrogen. Experiments with wheat and sorghum examined the enrichment of (15)N from cyanide

Species delimitation in Xanthium sect. Acanthoxanthium (Heliantheae, Asteraceae) and the neglected species Xanthium argenteum

open access: yesTAXON, Volume 73, Issue 5, Page 1251-1271, October 2024.
Abstract Xanthium is a genus of annual herbaceous plants that stands out within Asteraceae for being wind‐pollinated, diclinous monoecious, and bearing solitary pistillate flowers in peculiar spiny structures (burs). Xanthium sect. Acanthoxanthium is native to South America and characterized by the presence of trifurcate spines at the base of the ...

Advancements in Aptamer‐Driven DNA Nanostructures for Precision Drug Delivery

open access: yesAdvanced Science, Volume 11, Issue 26, July 10, 2024.
The review explores developments of aptamer‐driven DNA nanostructures for targeted drug delivery. DNA nanostructures, featuring tailorable platforms, integrate oligonucleotides to orchestrate molecular arrangements. Active targeting assays improve therapeutics delivery to cancerous cells by a “key‐lock” mechanism.
