Genetic networks involved in poplar root response to low nitrogen.

ABSTRACT: Perception of environmental cues and adaptation to changing environmental conditions are crucial for survival of sessile organisms like plants. This is even more important for woody perennial species like trees that can occupy a site for thousands of years. We have previously shown that under low nitrogen (LN), poplar trees display a vigorous and long-lasting root growth associated with global transcriptomic reprogramming and an activation of hierarchical genetic networks. Here we use computational analysis to better understand the network among the genes showing distinct chronological patterns of expression during the response. Our analyses confirm the previous findings, define new potential signaling pathways and the possible downstream targets of these signaling events.

A network of genes associated with poplar root development in response to low nitrogen.

Project description:Deployment of the root system is highly sensitive to the levels and spatial distribution of nutrients like nitrogen. However, the genetic determinants of these sensing and deployment mechanisms are still poorly understood. Previously, using system approaches based on temporal changes in root transcriptome in relation to low nitrogen (LN), we have been able to identify a module that activates root production in poplar in response to LN conditions. Here, using comparative, gene ontology and expression analyses, we provide further evidence that the genes in this module are indeed involved in regulation of root development under LN. Better understanding of these modules will enable approaches for breeding for better nitrogen use efficiency through development of a more sensitive and plastic root system.

Identification and Functional Prediction of Poplar Root circRNAs Involved in Treatment With Different Forms of Nitrogen.

Project description:Circular RNAs (circRNAs) are a class of noncoding RNA molecules with ring structures formed by covalent bonds and are commonly present in organisms, playing an important regulatory role in plant growth and development. However, the mechanism of circRNAs in poplar root responses to different forms of nitrogen (N) is still unclear. In this study, high-throughput sequencing was used to identify and predict the function of circRNAs in the roots of poplar exposed to three N forms [1 mM NO3 - (T1), 0.5 mM NH4NO3 (T2, control) and 1 mM NH4 + (T3)]. A total of 2,193 circRNAs were identified, and 37, 24 and 45 differentially expressed circRNAs (DECs) were screened in the T1-T2, T3-T2 and T1-T3 comparisons, respectively. In addition, 30 DECs could act as miRNA sponges, and several of them could bind miRNA family members that play key roles in response to different N forms, indicating their important functions in response to N and plant growth and development. Furthermore, we generated a competing endogenous RNA (ceRNA) regulatory network in poplar roots treated with three N forms. DECs could participate in responses to N in poplar roots through the ceRNA regulatory network, which mainly included N metabolism, amino acid metabolism and synthesis, response to NO3 - or NH4 + and remobilization of N. Together, these results provide new insights into the potential role of circRNAs in poplar root responses to different N forms.

OsPIN1b is Involved in Rice Seminal Root Elongation by Regulating Root Apical Meristem Activity in Response to Low Nitrogen and Phosphate.

Project description:The response of plant root development to nutrient deficiencies is critical for crop production. Auxin, nitric oxide (NO), and strigolactones (SLs) are important regulators of root growth under low-nitrogen and -phosphate (LN and LP) conditions. Polar auxin transport in plants, which is mainly dependent on auxin efflux protein PINs, creates local auxin maxima to form the basis for root initiation and elongation; however, the PIN genes that play an important role in LN- and LP-modulated root growth remain unclear. qRT-PCR analysis of OsPIN family genes showed that the expression of OsPIN1b is most abundant in root tip and is significantly downregulated by LN, LP, sodium nitroprusside (SNP, NO donor), and GR24 (analogue of SLs) treatments. Seminal roots in ospin1b mutants were shorter than those of the wild type; and the seminal root, [3H]IAA transport, and IAA concentration responses to LN, LP, SNP, and GR24 application were attenuated in ospin1b-1 mutants. pCYCB1;1::GUS expression was upregulated by LN, LP, SNP, and GR24 treatments in wild type, but not in the ospin1b-1 mutant, suggesting that OsPIN1b is involved in auxin transport and acts as a downstream mediator of NO and SLs to induce meristem activity in root tip in rice under LN and LP.

The WUSCHELa (PtoWUSa) is Involved in Developmental Plasticity of Adventitious Root in Poplar.

Project description:WUSCHEL-RELATED HOMEOBOX (WOX) transcription factors play critical roles in cell fate determination during plant development. As the founding member of the WOX family, WUSCHEL (WUS) is characterized for its role in maintaining stem cell in meristem. In this study, we investigated the function of Populus tomentosa WUSCHELa (PtoWUSa) in adventitious roots (ARs) in poplar. Expression profile analysis showed that PtoWUSa was not only expressed in shoot apical meristem and stem, but also expressed in ARs. Ectopic expression of PtoWUSa in Arabidopsis resulted in shortened primary root, as well as agravitropism and multiple branches. Overexpression of PtoWUSa in poplar increased the number of ARs but decreased their length. Moreover, the AR tip and lateral root tip became larger and swollen. In addition, the expression of auxin transporter genes PIN-FORMED were downregulated in ARs of transgenic plant. Taken together, these results suggest that PtoWUSa could be involved in AR development in poplar through regulating the polar auxin transport in ARs.

Comparative transcriptomic analysis uncovers conserved pathways involved in adventitious root formation in poplar.

Project description:Cutting propagation is widely used in establishing poplar plantations, and this approach requires efficient adventitious root (AR) forming capacities. Although poplar species are considered to form roots easily, interspecific variations in AR formation are still observed. To better understand the gene regulatory network underlying the conserved modified pathways that are essential for AR formation in poplar species, comparative transcriptomic approaches were applied to identify the conserved common genes that were differentially expressed during the AR formation processes in two poplar species (Populus × euramericana and P. simonii) in woody plant medium (WPM). A total of 2146 genes were identified as conserved genes that shared similar gene expression profiles in at least one comparison. These conserved genes were enriched in diverse hormone signaling pathways, as well as the mitogen-associated protein kinase (MAPK) signaling pathway, suggesting an important role for signaling transduction in coordinating external stimuli and endogenous physiological status during AR regulation in poplar. Furthermore, the co-expression network analysis of conserved genes allowed identification of several co-expressed modules (CM) that are co-expressed with distinct biological functions, for instance, CM1 was enriched in defense response and hormone signaling, CM2 and CM3 were overrepresented in defense response-related pathways and for cell cycle, respectively. These results suggest that the AR formation processes in poplar were finely tuned at the transcriptomic level by integrating multiple biological processes essential for AR formation. Our results suggest conserved machinery for AR formation in poplar and generated informative gene co-expression networks that describe the basis of AR formation in these species.Supplementary informationThe online version contains supplementary material available at 10.1007/s12298-021-01054-7.

Identification and characterization of circRNAs involved in the regulation of low nitrogen-promoted root growth in hexaploid wheat.

Project description:BackgroundCircRNAs are widespread in plants and play important roles in response to abiotic stresses. Low nitrogen (LN) promotes the growth of plant root system, allowing it to explore more nitrogen. However, whether circRNAs involved in the response to LN stress and the regulation of LN-promoted root growth in wheat remains unclear.MethodsTwo wheat varieties (LH9 and XN979) with contrasting root phenotypes to LN stress were used as materials to identify circRNAs under control and LN conditions by using high-throughput sequencing technology.ResultsSix differentially expressed circRNAs (DECs) involved in the common response to LN stress and 23 DECs involved in the regulation of LN-promoted root growth were successfully identified. GO analysis of the DEC-host genes involved in the regulation of LN-promoted root growth showed that GO terms related to biological regulation, responses to stimuli and signalling were significantly enriched. Moreover, seven DECs were predicted to have miRNA binding sites and may serve as miRNA sponges to capture miRNAs from their target genes.ConclusionsLN stress altered the expression profiles of circRNAs in wheat. This is the first report of LN stress responsive circRNAs in plants. Our results provided new clues for investigating the functions of circRNAs in response to LN stress and in the regulation of LN-promoted wheat root growth.

Root aeration improves growth and nitrogen accumulation in rice seedlings under low nitrogen.

Project description:In wetland soils, changes in oxygen (O2) level in the rhizosphere are believed to influence the behaviour of nutrients and their usage by plants. However, the effect of aeration on nitrogen (N) acquisition under different N supply conditions remains largely unknown. In this study, the rice cultivars Yangdao 6 (YD6, with higher root aerenchyma abundance) and Nongken 57 (NK57, with lower root aerenchyma abundance) were used to evaluate the effects of aeration on rice growth and N accumulation. Our results showed that the number of adventitious roots and the root surface area increased significantly, and ethylene production and aerenchyma formation decreased in both cultivars after external aeration (EA). Five N treatments, including no N (-N), 0.125 mM NH4NO3 (LN), 1.25 mM Ca(NO3)2 (NO3-N), 1.25 mM (NH4)2SO4 (NH4-N) and 1.25 mM NH4NO3 (N/N), were applied to YD6 and NK57 for 2 days under internal aeration or EA conditions. External aeration increased the root biomass in both cultivars and the shoot biomass in NK57 by 18-50 %. The total N concentrations in roots of YD6 grown under -N and LN and of NK57 grown under NO3-N were increased by EA. Expression of OsPAD4, one of four putative genes regulating aerenchyma formation, showed a similar pattern alongside changes in the ethylene level in the EA-treated rice irrespective of the N treatments. Furthermore, expression of the high-affinity nitrate transporter gene OsNRT2.1 was increased by EA under -N, LN and NO3-N conditions. Our data provide evidence of an interaction between O2 and the supply of N in ethylene production, aerenchyma formation and N nutrition through modification of the expression of OsPAD4 and OsNRT2.1.

Transcriptomic analysis reveals the gene regulatory networks involved in leaf and root response to osmotic stress in tomato.

Project description:IntroductionTomato (Solanum lycopersicum L.) is a major horticultural crop that is cultivated worldwide and is characteristic of the Mediterranean agricultural system. It represents a key component of the diet of billion people and an important source of vitamins and carotenoids. Tomato cultivation in open field often experiences drought episodes, leading to severe yield losses, since most modern cultivars are sensitive to water deficit. Water stress leads to changes in the expression of stress-responsive genes in different plant tissues, and transcriptomics can support the identification of genes and pathways regulating this response.MethodsHere, we performed a transcriptomic analysis of two tomato genotypes, M82 and Tondo, in response to a PEG-mediated osmotic treatment. The analysis was conducted separately on leaves and roots to characterize the specific response of these two organs.ResultsA total of 6,267 differentially expressed transcripts related to stress response was detected. The construction of gene co-expression networks defined the molecular pathways of the common and specific responses of leaf and root. The common response was characterized by ABA-dependent and ABA-independent signaling pathways, and by the interconnection between ABA and JA signaling. The root-specific response concerned genes involved in cell wall metabolism and remodeling, whereas the leaf-specific response was principally related to leaf senescence and ethylene signaling. The transcription factors representing the hubs of these regulatory networks were identified. Some of them have not yet been characterized and can represent novel candidates for tolerance.DiscussionThis work shed new light on the regulatory networks occurring in tomato leaf and root under osmotic stress and set the base for an in-depth characterization of novel stress-related genes that may represent potential candidates for improving tolerance to abiotic stress in tomato.

Interaction of BES1 and LBD37 transcription factors modulates brassinosteroid-regulated root forging response under low nitrogen in arabidopsis.

Project description:Brassinosteriod (BR) plays important roles in regulation of plant growth, development and environmental responses. BR signaling regulates multiple biological processes through controlling the activity of BES1/BZR1 regulators. Apart from the roles in the promotion of plant growth, BR is also involved in regulation of the root foraging response under low nitrogen, however how BR signaling regulate this process remains unclear. Here we show that BES1 and LBD37 antagonistically regulate root foraging response under low nitrogen conditions. Both the transcriptional level and dephosphorylated level of BES1, is significant induced by low nitrogen, predominantly in root. Phenotypic analysis showed that BES1 gain-of-function mutant or BES1 overexpression transgenic plants exhibits progressive outgrowth of lateral root in response to low nitrogen and BES1 negatively regulates repressors of nitrate signaling pathway and positively regulates several key genes required for NO3 - uptake and signaling. In contrast, BES1 knock-down mutant BES1-RNAi exhibited a dramatical reduction of lateral root elongation in response to low N. Furthermore, we identified a BES1 interacting protein, LBD37, which is a negative repressor of N availability signals. Our results showed that BES1 can inhibit LBD37 transcriptional repression on N-responsive genes. Our results thus demonstrated that BES1-LBD37 module acts critical nodes to integrate BR signaling and nitrogen signaling to modulate the root forging response at LN condition.

Knockdown of OsNRT2.4 modulates root morphology and alters nitrogen metabolism in response to low nitrate availability in rice

Project description:The expression patterns of the NRT2 genes have been well described; however, the role of OsNRT2.4 in root growth is not well known. In this study, we thus aimed at investigating the role of high-affinity NO3− transport OsNRT2.4 in root growth modulation. Through the amiRNA-mediated gene silencing technique, we successfully obtained osnrt2.4 knockdown lines to study the role of OsNRT2.4 on root growth under low nitrate conditions. We performed real-time PCR analysis to investigate the relative gene expression level in root and shoot, soluble metabolites, and measurement of root system. Knockdown of OsNRT2.4 decreased rice growth. The comparison with wild-type (WT) plants showed that (i) knockdown of OsNRT2.4 inhibited root formation under low NO3− supply; (ii) we demonstrated that the mutant lines had significantly increased NO3− uptake than WT plants when grown in different nitrate supplies; (iii) osnrt2.4 knockdown lines showed an alteration in nitrogen metabolism, and this affected the root growth; and (iv) the downregulation of OsNRT2.4 enhanced the expression of gene response of low external NO3− concentrations. Herein we provide new insights in OsNRT2.4 functions. Our data demonstrated that OsNRT2.4 plays a role in root growth, nitrogen metabolic pathway and probably have functions in nitrate transport from root to shoot under low nitrate availability in rice.
