HighlightAuxin, ethylene, and cytokinin regulate root-hair initiation unequally but promote elongation synergistically. Detailed analyses suggest that these hormones regulate a similar set of root hair-specific genes through diverted upstream signaling pathways.
MADS-box transcription factors are vital regulators participating in plant growth and development process and the functions of most of them are still unknown. ANR1 was reported to play a key role in controlling lateral root development through nitrate signal in Arabidopsis. OsMADS25 is one of five ANR1-like genes in Oryza Sativa and belongs to the ANR1 clade. Here we have investigated the role of OsMADS25 in the plant’s responses to external nitrate in Oryza Sativa. Our results showed that OsMADS25 protein was found in the nucleus as well as in the cytoplasm. Over-expression of OsMADS25 significantly promoted lateral and primary root growth as well as shoot growth in a nitrate-dependent manner in Arabidopsis. OsMADS25 overexpression in transgenic rice resulted in significantly increased primary root length, lateral root number, lateral root length and shoot fresh weight in the presence of nitrate. Down-regulation of OsMADS25 in transgenic rice exhibited significantly reduced shoot and root growth in the presence of nitrate. Furthermore, over-expression of OsMADS25 in transgenic rice promoted nitrate accumulation and significantly increased the expressions of nitrate transporter genes at high rates of nitrate supply while down-regulation of OsMADS25 produced the opposite effect. Taken together, our findings suggest that OsMADS25 is a positive regulator control lateral and primary root development in rice.
In the past decade, the rapid development of portable electronic devices, electric vehicles, and electrical devices has stimulated extensive interest in fundamental research and the commercialization of electrochemical energy‐storage systems. Biomass‐derived carbon has garnered significant research attention as an efficient, inexpensive, and eco‐friendly active material for energy‐storage systems. Therefore, high‐performance carbonaceous materials, derived from renewable sources, have been utilized as electrode materials in sodium‐ion batteries and sodium‐ion capacitors. Herein, the charge‐storage mechanism and utilization of biomass‐derived carbon for sodium storage in batteries and capacitors are summarized. In particular, the structure–performance relationship of biomass‐derived carbon for sodium storage in the form of batteries and capacitors is discussed. Despite the fact that further research is required to optimize the process and application of biomass‐derived carbon in energy‐storage devices, the current review demonstrates the potential of carbonaceous materials for next‐generation sodium‐related energy‐storage applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
