Understanding how plant responses to nitrate availability is essential for improving nitrogen use efficiency in crops. Herein, we demonstrated that the basic helix-loop-helix (bHLH) transcription factor TabHLH489 plays a crucial negative regulatory role in wheat nitrate signaling. Overexpressing <i>TabHLH489</i> significantly reduced nitrate-promoted wheat growth and grain yield. Transcriptomic analysis showed that approximately 75% of nitrate-responsive genes were no longerregulated by nitrate in the <i>TabHLH489</i> overexpression lines. TabHLH489 directly interacts with TaNLP7-3A, the wheat homolog protein of NIN-like protein 7 (NLP7), a central transcription factor in nitrate signaling. This interaction impairs TaNLP7-3A's ability to bind DNA, thereby inhibiting its transcriptional activity. Moreover, TabHLH489 induces the accumulation of reactive oxygen species (ROS) to reduce the nuclear localization of TaNLP7-3A, thereby diminishing its effectiveness in regulating the plant nitrogen response. These findings highlight the intricate regulatory mechanism by which TabHLH489 modulates TaNLP7-3A activity through direct interaction and ROS-mediated inhibition of nuclear localization.

Stomatal development is orchestrated by intrinsic developmental programs, hormonal controls, and environmental cues. The steroid hormone brassinosteroid (BR) inhibits stomatal lineage progression by regulating BIN2 and BSL proteins in leaves. Notably, BR is known to promote stomatal development in hypocotyls as opposed to leaves; however, its molecular mechanism remains elusive. Here, we show that BR signaling has a dual regulatory role in controlling stomatal development in Arabidopsis hypocotyls. We found that brassinolide (BL; the most active BR) regulates stomatal development differently in a concentration-dependent manner. At low and moderate concentrations, BL promoted stomatal formation by upregulating the expression of SPEECHLESS (<i>SPCH</i>) and its target genes independently of BIN2 regulation. In contrast, high concentrations of BL and bikinin, which is a specific inhibitor of BIN2 and its homologs, significantly reduced stomatal formation. Genetic analyses revealed that BIN2 regulates stomatal development in hypocotyls through molecular mechanisms distinct from the regulatory mechanism of the cotyledons. In hypocotyls, BIN2 promoted stomatal development by inactivating BZR1, which suppresses the expression of <i>SPCH</i> and its target genes. Taken together, our results suggest that BR precisely coordinates the stomatal development of hypocotyls using an antagonistic control of <i>SPCH</i> expression via BZR1-dependent and BZR1-independent transcriptional regulation.</p></div>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"67 2","pages":"258-275"},"PeriodicalIF":9.3,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142875836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
