Abstract:
Biostimulants are quickly becoming recognized by regulatory bodies and government agencies as main-stream agricultural products. To support this recognition, research programs are being developed to study effects ranging from genomics to metabolomics to transcriptomics to proteomics and phenomics. All of these sciences shed light on the effects of various biostimulants on the upregulation and downregulation of genes, and ultimately, effects on plant growth and development. Our research has investigated many of the effects of Ascophyllum nodosum extract (ANE) on biotic and abiotic stress factors in model plants and crop production. ANE has been found to elicit measurable genomic responses that influence protein (anti-oxidant) synthesis and activity, and provide a level of stress resistance/tolerance to treated plants. Additional research shows benefits ranging from nutritional to hormonal. This paper provides a brief overview of our ongoing and published research in this area and relies heavily on peer-reviewed, published information arising from our internal and external research program. It is hoped that this information can be used by researchers and practitioners alike to help develop sustainable, integrated crop management programs for healthy, productive plant production.
