Uneven hormone distribution in plants regulates cell division and growth, biologists discover

New research from an international team of plant biologists, led by researchers at the VIB-UGent Center for Plant Systems Biology, has revealed crucial insights into the role brassinosteroids—essential plant hormones—play in regulating cell division and growth. The findings, published in Cell, provide a comprehensive understanding of how these hormones influence development at the cellular level.

Effect of 28-Homobrassinolide on Fatty Acid Metabolism During Germination of Crambe tatarica Under Salinity Stress - Cytology and Genetics

To study the effect of brassinosteroids and salinity stress on the fatty acid metabolism in the seeds of oil plants, the authors analyzed the turnover of fatty acids in the seeds of Crambe tatarica under the mentioned conditions. The results of gas-liquid chromatography and mass-spectrometry demonstrated the decrease in the level of palmitic and linoleic fatty acids along with the increase in the level of oleic, eicosenoic, and docosenoic fatty acids in C. tatarica seeds in response to 28-homobrassinolide under salinity stress on some stages of seed germination. These regularities allowed for the assumption that 28-homobrassinolide promotes the stabilization of fatty acid composition of C. tatarica seeds, disrupted under salinity stress. This may indicate the possibility of modulating the activity or expression of desaturase genes and the enzymes of fatty acid oxidation in the anwer on brassinosteroids.

Team reports on relationship between contents of diosgenin and brassinosteroids in Dioscorea zingiberensis

Diosgenin, a secondary metabolite isolated from the Dioscorea spp. plant family, is an irreplaceable and ideal starting material for the synthesis of steroid hormone drugs. Dioscorea zingiberensis is the world's most desirable and important plant source of steroid hormone drugs.

1st I've heard of #brassinosteroids and #triacontanol. Some other interesting ingredients like B vitamins. I had just been reading about how riboflavin is also an antioxidant in addition to enzyme cofactor.

Sounds similar to application of compost tea, but scalable to commercial farming.
