Abstract
The agricultural industry is rapidly accepting daily changes and updates, and expanding to meet the basic demands of humanity. The main objective of modern agricultural practices is high profits with minimal investment, without upsetting any other form of life or abiotic factors. According to this principle, nanofertilizers are recommended for use in agriculture and are classified in different ways based on their nutritive value, functional role in the environment, chemical composition, and form of application to ensure their persistent availability in the required quantities. These nanofertilizers meet the global crop nutrient requirement of 191.8 million metric tons along with multitudes of added value, and which are highly endorsed in the agricultural field compared to other chemical fertilizers, or their usage can be reduced to less than 50% by the use of nanofertilizers. In this review, we discuss different types of nanofertilizers, their effects on crop yield, stress tolerance, and their impact on the environment. Furthermore, the different types of nanofertilizer delivery, modes of action, and toxic impacts of nanofertilizers have been discussed. Although a large number of commercially successful effects of nanofertilizers have been demonstrated, the effects of biomagnification and cellular transformation are still disputed. The effect of the biomagnification of nanofertilizers remains unclear. A suitable strategy must be developed to easily recycle nanofertilizers. It is the need of the hour to accept the use of nanofertilizers in parallel to addressing this issue.

Phosphorus-based nanomaterials as a potential phosphate fertilizer for sustainable agricultural development. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 205:108172. [PMID: 37956611 DOI: 10.1016/j.plaphy.2023.108172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 10/10/2023] [Accepted: 11/06/2023] [Indexed: 11/15/2023]
Abstract
Phosphorus-based nanomaterials (PNMs) have been reported to have substantial promise for promoting plant growth, improving plant tolerance mechanisms, and increasing resistance to pathogenic organisms. Recent scientific investigation has demonstrated that utilizing PNMs can enhance plant physiological growth, photosynthetic pigments, antioxidant system, metabolism, nutrient absorption, rhizosphere secretion, and soil nutrients activation. Previous research on PNMs mostly concentrated on calcium phosphate, zeolite, and chitosan, with little systematic summarization, demanding a thorough evaluation of PNMs' broader uses. In our current review article, we address the knowledge gap by classifying PNMs according to green synthesis methods and the valence state of phosphorus while elucidating the underlying mechanisms through which these PNMs facilitate plant growth. In addition, we also targeted some strategies to improve the bioavailability of PNMs, offering valuable insights for the future design and safe implementation of PNMs in agricultural practices.

Singh NRR, Roychowdhury A, Srivastava R, Gaganan GA, Parida AP, Kumar R. Silencing of SlSPX1 and SlSPX2 promote growth and root mycorrhization in tomato (Solanum lycopersicum L.) seedlings. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2023; 333:111723. [PMID: 37142098 DOI: 10.1016/j.plantsci.2023.111723] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 04/10/2023] [Accepted: 05/01/2023] [Indexed: 05/06/2023]
Abstract
Owing to the essential requirement of phosphorus (P) for growth and development, plants tightly control inorganic phosphate (Pi) homeostasis. SPX-PHR regulatory circuit not only control phosphate homeostasis responses but also root mycorrhization by arbuscular mycorrhiza (AM) fungi. Besides sensing Pi deficiency, SPX (SYG1/Pho81/XPR1) proteins also control the transcription of P starvation inducible (PSI) genes by blocking the activity of PHR1 (PHOSPHATE STARVATION RESPONSE1) homologs in plants under Pi-sufficient conditions. However, the roles of SPX members in Pi homeostasis and AM fungi colonization remain to be fully recognized in tomato. In this study, we identified 17 SPX-domain containing members in the tomato genome. Transcript profiling revealed the high Pi-specific nature of their activation. Four SlSPX members have also induced in AM colonized roots. Interestingly, we found that SlSPX1 and SlSPX2 are induced by P starvation and AM colonization. Further, SlSPX1 and SlSPX2 exhibited varying degrees of interaction with the PHR homologs in this study. Virus-induced gene silencing-based (VIGS) transcript inhibition of these genes alone or together promoted the accumulation of higher total soluble Pi in tomato seedlings and improved their growth. It also enhanced AM fungi colonization in the roots of SlSPX1 and SlSPX2 silenced seedlings. Overall, the present study provides evidence in support of SlSPX members being good candidates for improving AM fungi colonization potential in tomato.
