“…In particular, the expression of this miRNA has been suggested to restrict sulfur assimilation in the roots and consequently to promote S transport from root to shoot under S deficiency [ 75 ]. Consistently, under biotic stress OsmiR395 expression increases to limit sulfate assimilation and to promote bacterial neutralization by sulfate accumulation [ 76 ].…”

Knowledge of the stress-induced metabolic alterations in tolerant and sensitive plants is pivotal for identifying interesting traits that improve plant resilience toward unfavorable environmental conditions. This represents a hot topic area of plant science, particularly for crops, due to its implication in food security. Two rice varieties showing dissimilar resistance to salt, Baldo and Vialone Nano, have been studied to investigate the mechanisms underpinning tolerance toward salinity, and these studies have focused on the root system. A detailed analysis of the salt stress-dependent modulation of the redox network is here presented. The different phenotype observed after salt exposure in the two rice varieties is coherent with a differential regulation of cell-cycle progression and cell-death patterns observed at root level. Baldo, the tolerant variety, already showed a highly responsive antioxidative capacity in control conditions. Consistently, stressed Baldo plants showed a different pattern of H2O2 accumulation compared to Vialone Nano. Moreover, glutathione metabolism was finely modulated at transcriptional, post-transcriptional, and post-translational levels in Baldo. These results contribute to highlight the role of ROS and antioxidative pathways as a part of a complex redox network activated in rice toward salt stress.

“…Its absorption and assimilation are particularly important for the metal tolerance of plants. Studies have shown that sulfate transporter 2; 1 (SULTR2; 1) and ATP sulfonylase 1, 3, 4 (APS 1, 3, 4) are sulfate-assimilation-related genes that can be targeted and regulated by miR395, which proves that miR395 is involved in the process of sulfur assimilation [ 60 , 101 , 102 , 103 ]. In B. napus , overexpressing miRNA395 can strengthen Cd tolerance by regulating the increase in the pure content of GSH and non-protein sulfur [ 60 ].…”

“…Some recent approaches showed that exogenous addition of auxin or stimulation of endogenous levels can prevent growth inhibition and improve heavy metal tolerance, and miRNAs appear to be involved in the regulation of auxin homeostasis. High-throughput RNA sequencing studies in Z. mays , Sedum alfredii H. , and O. sativa have identified a large number of Cd-responsive miRNAs, some of which are associated with auxin signaling [ 56 , 60 , 61 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 ]. Research showed that miR393 functions in plant Cd-stress tolerance, which targets transport inhibitor response 1 (TIR1) in rice [ 100 ].…”

Environmental metal pollution is a common problem threatening sustainable and safe crop production. Heavy metals (HMs) cause toxicity by targeting key molecules and life processes in plant cells. Plants counteract excess metals in the environment by enhancing defense responses, such as metal chelation, isolation to vacuoles, regulating metal intake through transporters, and strengthening antioxidant mechanisms. In recent years, microRNAs (miRNAs), as a small non-coding RNA, have become the central regulator of a variety of abiotic stresses, including HMs. With the introduction of the latest technologies such as next-generation sequencing (NGS), more and more miRNAs have been widely recognized in several plants due to their diverse roles. Metal-regulated miRNAs and their target genes are part of a complex regulatory network. Known miRNAs coordinate plant responses to metal stress through antioxidant functions, root growth, hormone signals, transcription factors (TF), and metal transporters. This article reviews the research progress of miRNAs in the stress response of plants to the accumulation of HMs, such as Cu, Cd, Hg, Cr, and Al, and the toxicity of heavy metal ions.

“…Sulfur starvation affects the expression of miR156, miR160, miR167, miR164, miR168, miR394 and miR395 in Brassica napus ( Huang et al., 2010 ). MiR395 is the main miRNA responsible for sulfur uptake and translocation ( Liang et al., 2010 ; Yang et al., 2022 ). It targets and inhibits the expression of the ATP sulfurylase gene, APS1 , and the sulfate transporter genes, SULTR2;1 and SULTR2;2 ( Liang et al., 2010 ).…”

Symbiotic nitrogen fixation is an important component in the nitrogen cycle and is a potential solution for sustainable agriculture. It is the result of the interactions between the plant host, mostly restricted to legume species, and the rhizobial symbiont. From the first encounter between the host and the symbiont to eventual successful nitrogen fixation, there are delicate processes involved, such as nodule organogenesis, rhizobial infection thread progression, differentiation of the bacteroid, deregulation of the host defense systems, and reallocation of resources. All these processes are tightly regulated at different levels. Recent evidence revealed that non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), participate in these processes by controlling the transcription and translation of effector genes. In general, ncRNAs are functional transcripts without translation potential and are important gene regulators. MiRNAs, negative gene regulators, bind to the target mRNAs and repress protein production by causing the cleavage of mRNA and translational silencing. LncRNAs affect the formation of chromosomal loops, DNA methylation, histone modification, and alternative splicing to modulate gene expression. Both lncRNAs and circRNAs could serve as target mimics of miRNA to inhibit miRNA functions. In this review, we summarized and discussed the current understanding of the roles of ncRNAs in legume nodulation and nitrogen fixation in the root nodule, mainly focusing on their regulation of hormone signal transduction, the autoregulation of nodulation (AON) pathway and nutrient homeostasis in nodules. Unraveling the mediation of legume nodulation by ncRNAs will give us new insights into designing higher-performance leguminous crops for sustainable agriculture.
