They are increasingly replacing the use of chemical fertilizers, which have harmful consequences for the environment. Biostimulants are derived from a variety of sources, including micro-organisms, plant extracts, algae, hydrolysates of animal or plant proteins, and humic substances. They have been tested on a variety of crops under normal and abiotic stress conditions and have succeed each time in proving their effectiveness in improving the chemical composition of plants. This improvement has a positive impact on plants' nutritional properties and resistance to stress conditions. These effects not only have positive impact on human health, but also on climate change challenges, and increasing demand for food. However, the difficulty in interpreting the results obtained from the use of biostimulants is due to their variable composition, which is not always known, making it difficult to determine their modes of action and hence their regulation. The purpose of this review is to highlight the positive effect of biostimulants on the chemical composition of food crops under normal or abiotic stress conditions. It presents an overview of chemical variability in plants and gathers studies that help clarify the effect of biostimulants. Additional studies on economic aspects, research gaps, and future prospects in the field of biostimulants are also discussed.</div></div>","PeriodicalId":38090,"journal":{"name":"Current Plant Biology","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142577931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three members of the <em>Arabidopsis thaliana</em> B-BOX DOMAIN PROTEIN (BBX) family, <em>BBX14</em>, <em>BBX15</em>, and <em>BBX16</em> (hereafter <em>BBX14/15/16</em>), redundantly regulate flowering time, but whether this genetic redundancy also affects the regulation of photomorphogenesis remains unclear. Here, we show that light induces <em>BBX14/15/16</em> expression primarily in the hypocotyl, where BBX14/15/16 redundantly repress hypocotyl elongation. PHYTOCHROME-INTERACTING FACTORs (PIFs) negatively regulate <em>BBX14/15/16</em> expression mainly through GOLDEN-LIKE proteins (GLKs); however, analyses of ChIP-seq data showed that PIFs are recruited to the <em>BBX14/15/16</em> loci and can also regulate these genes independently of GLKs. ELONGATED HYPOCOTYL 5 (HY5), a major regulator of photomorphogenesis, also directly binds to the <em>BBX14/15/16</em> loci and regulates their expression. Simultaneous knockdown of <em>BBX14/15/16</em> resulted in significant downregulation of <em>HY5</em> and upregulation of <em>PIF</em>s, suggesting that these factors participate in a feedback regulatory loop. Indeed, BBX14/15/16 induced <em>HY5</em> promoter activity by binding to the <em>HY5</em> promoter. The brassinosteroid-responsive gene <em>TOUCH4</em> (<em>TCH4</em>) and several auxin-responsive <em>SMALL AUXIN UPREGULATED RNA</em> (<em>SAUR</em>) genes were upregulated in the <em>BBX14/15/16</em> knockdown plants, suggesting that auxin and brassinosteroids might participate in BBX14/15/16-mediated hypocotyl regulation. Mutating the predicted BBX-binding sites in <em>SAUR4</em> and <em>TCH4</em> impaired their regulation by BBX14/15/16.

Yet, the beneficial effect of CKs is counteracted by cytokinin oxidase/dehydrogenase (CKO/CKX, EC 1.5.99.12) enzymes and by <em>N</em>- and/or <em>O</em>-glycosylation. Additionally, research on CKs and CKX is often limited to model plants studied in isolation, and sparsely covers non-model plants exposed to abiotic stresses. Thus, this review explored the role of CKs and CKX inhibitors in mitigating abiotic stresses in model and non-model plants. We also examined possible crosstalk mechanisms of CKs with auxins, polyamines, and other major phytohormones. A detailed literature search was conducted using several databases including Web of Science, Google Scholar, ScienceDirect, Scopus, and PubMed.
