Unlocking the secrets of plant steroid hormones: the yin and yang of diosgenin and brassinosteroids

A recent study revealed the complex interplay between diosgenin (DG) and brassinosteroids (BRs) in Dioscorea zingiberensis. By integrating genome-wide methylation, transcriptome, and metabolite data, researchers constructed a regulatory network showing how DG and BRs balance each other. These findings offer new insights into plant secondary metabolism and potential for enhancing DG production for steroid hormone drugs.

Membrane Technology: Looking Deep into Smallest Pores

Membranes of vertically aligned carbon nanotubes (VaCNT) can be used to clean or desalinate water at high flow rate and low pressure. Recently, researchers of Karlsruhe Institute of Technology (KIT) and partners carried out steroid hormone adsorption experiments to study the interplay of forces in the small pores. They found that VaCNT of specific pore geometry and pore surface structure are suited for use as highly selective membranes. The researchers report in Nature Communications.
