Yang H, Zhang Y, Lyu S, Liu Y, Jian S, Deng S. MpNAC1, a transcription factor from the mangrove associate Millettia pinnata, confers salt and drought stress tolerance in transgenic Arabidopsis and rice. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2024; 211:108721. [PMID: 38739961 DOI: 10.1016/j.plaphy.2024.108721] [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: 01/22/2024] [Revised: 04/02/2024] [Accepted: 05/08/2024] [Indexed: 05/16/2024]
Abstract
Pongamia (Millettia pinnata Syn. Pongamia pinnata), a mangrove associate plant, exhibits good stress tolerance, making it a treasure of genetic resources for crop improvement. NAC proteins are plant-specific transcription factors, which have been elucidated to participate in the regulation and tolerance of abiotic stresses (such as salt and drought). Here, we identified a salt-induced gene from Pongamia, MpNAC1, which encodes an NAC factor sharing five highly conserved domains with other NACs and exhibits close homology to AtNAC19/AtNAC55/AtNAC72 in Arabidopsis. MpNAC1 showed nuclear localization and transcriptional activator activity. MpNAC1-overexpressing Arabidopsis exhibited significantly stronger salt and drought tolerance compared with wild-type plants. The expression levels of stress-responsive genes were activated in transgenic Arabidopsis. Furthermore, the heterologous expression of MpNAC1 also enhanced the salt and drought tolerance of transgenic rice. The major agronomic traits, such as plant height and tiller number, panicle length, grain size, and yield, were similar between the transgenic lines and wild type under normal field growth conditions. RNA-Seq analysis revealed that MpNAC1 significantly up-regulated stress-responsive genes and activated the biosynthesis of secondary metabolites such as flavonoids, resulting in increased stress tolerance. Taken together, the MpNAC1 increased salt and drought stress tolerance in transgenic plants and did not retard the plant growth and development under normal growth conditions, suggesting the potential of MpNAC1 in breeding stress-resilient crops.

PLANTS (BASEL, SWITZERLAND) 2023; 13:2. [PMID: 38202310 PMCID: PMC10780645 DOI: 10.3390/plants13010002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 12/11/2023] [Accepted: 12/13/2023] [Indexed: 01/12/2024]
Abstract
Non-structural carbohydrates (NSCs) required for bamboo shoot development, the critical stage that determines the yield of a bamboo stand, originate from the parent bamboo with the complex underground system. However, the metabolic mechanism of NSCs in the rhizome-culm system during bamboo shoot development remains unclear. In this study, we focused on the changes of NSCs in the rhizome-culm system and used anatomical, physiological, and biochemical methods to investigate the metabolism of NSCs in bamboo shoots of Phyllostachys edulis and the role of NSCs supply in the parent bamboo at different ages. The results showed that NSCs were accumulated and consumed from the bottom to the top in a bamboo shoot, which was consistent with the developmental pattern. The starch granules were stored in advance. The bamboo sheath stored starch from the dormant stage of shoot buds. The functions of culms and rhizomes showed age-dependent differences. Adult culms showed the highest capacity to provide NSCs, with more stored NSCs and higher β-amylase activity. Conversely, young culms seemed to prefer their growth, while old culms tended to store starch. Accordingly, adult rhizomes preferred sugar transport due to the lowest starch storage, lower ADP-glucose pyrophosphorylase (AGPase) activity, and higher β-amylase activity, while young and old rhizomes tended to prefer starch storage. These results provide a basis for further understanding of nutrient metabolism in bamboo stands.

Abstract
The PLATZ (plant AT protein and zinc-binding protein) transcription factor family is involved in the regulation of plant growth and development and plant stress response. In this study, 24 SlPLATZs were identified from the cultivated tomato genome and classified into four groups based on the similarity of conserved patterns among members of the same subfamily. Fragment duplication was an important way to expand the SlPLATZ gene family in tomatoes, and the sequential order of tomato PLATZ genes in the evolution of monocotyledonous and dicotyledonous plants and the roles they played were hypothesized. Expression profiles based on quantitative real-time reverse transcription PCR showed that SlPLATZ was involved in the growth of different tissues in tomatoes. SlPLATZ21 acts mainly in the leaves. SlPLATZ9, SlPLATZ21, and SlPLATZ23 were primarily involved in the red ripening, expanding, and mature green periods of fruit, respectively. In addition, SlPLATZ1 was found to play an important role in salt stress. This study will lay the foundation for the analysis of the biological functions of SlPLATZ genes and will also provide a theoretical basis for the selection and breeding of new tomato varieties and germplasm innovation.

Abstract
Increased food production to cater the need of growing population is one of the major global challenges. Currently, agro-productivity is under threat due to shrinking arable land, increased anthropogenic activities and changes in the climate leading to frequent flash floods, prolonged droughts and sudden fluctuation of temperature. Further, warm climatic conditions increase disease and pest incidences, ultimately reducing crop yield. Hence, collaborated global efforts are required to adopt environmentally safe and sustainable agro practices to boost crop growth and productivity. Biostimulants appear as a promising means to improve growth of plants even under stressful conditions. Among various categories of biostimulants, microbial biostimulants are composed of microorganisms such as plant growth-promoting rhizobacteria (PGPR) and/or microbes which stimulate nutrient uptake, produce secondary metabolites, siderophores, hormones and organic acids, participate in nitrogen fixation, imparts stress tolerance, enhance crop quality and yield when applied to the plants. Though numerous studies convincingly elucidate the positive effects of PGPR-based biostimulants on plants, yet information is meagre regarding the mechanism of action and the key signaling pathways (plant hormone modulations, expression of pathogenesis-related proteins, antioxidants, osmolytes etc.) triggered by these biostimulants in plants. Hence, the present review focuses on the molecular pathways activated by PGPR based biostimulants in plants facing abiotic and biotic challenges. The review also analyses the common mechanisms modulated by these biostimulants in plants to combat abiotic and biotic stresses. Further, the review highlights the traits that have been modified through transgenic approach leading to physiological responses akin to the application of PGPR in the target plants.

JOURNAL OF PLANT PHYSIOLOGY 2023; 280:153865. [PMID: 36459885 DOI: 10.1016/j.jplph.2022.153865] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 11/09/2022] [Accepted: 11/09/2022] [Indexed: 06/17/2023]
Abstract
The lateral organ boundaries domain (LBD), a unique family of transcription factors in higher plants, plays a key role in plant growth and development, and stress response. Here, we report on the novel lateral organ boundaries domain (LBD) gene PheLBD29, a nuclear localization protein that can bind the conserved GCCCCG sequence, as determined by electrophoretic mobility shift assay (EMSA). PheLBD29 was highly expressed in blade leaf and significantly induced by polyethylene glycol (PEG). Overexpression of PheLBD29 leads to small and abaxially rolled leaves in Arabidopsis, and anatomically, 35S:PheLBD29 Arabidopsis leaves showed transformation of adaxial cells into abaxial cells. Moreover, overexpression of PheLBD29 in Arabidopsis increased plant tolerance to drought stress, by accumulation of more soluble sugars, less malondialdehyde (MDA), and had lower REL levels under drought stress. Transient expression assay revealed PheLBD29 directly bound to the promoter region of RAB18. In addition, 35S:PheLBD29 Arabidopsis showed higher sensitivity to abscisic acid (ABA) than the wild type. Therefore, we conclude that PheLBD29 may participate in the ABA-dependent signaling pathway to improve drought tolerance. Our study provides new evidence for a Moso bamboo LBD protein regulatory module in leaf curvature and drought resistance.

Abstract
Plants are sessile organisms that evolve with a flexible signal transduction system in order to rapidly respond to environmental changes. Drought, a common abiotic stress, affects multiple plant developmental processes especially growth. In response to drought stress, an intricate hierarchical regulatory network is established in plant to survive from the extreme environment. The transcriptional regulation carried out by transcription factors (TFs) is the most important step for the establishment of the network. In this review, we summarized almost all the TFs that have been reported to participate in drought tolerance (DT) in plant. Totally 466 TFs from 86 plant species that mostly belong to 11 families are collected here. This demonstrates that TFs in these 11 families are the main transcriptional regulators of plant DT. The regulatory network is built by direct protein-protein interaction or mutual regulation of TFs. TFs receive upstream signals possibly via post-transcriptional regulation and output signals to downstream targets via direct binding to their promoters to regulate gene expression.

Identification and Characterization of circRNAs under Drought Stress in Moso Bamboo (Phyllostachys edulis). FORESTS 2022.

Abstract
Circular RNAs (circRNAs) are a class of endogenous noncoding RNAs formed by 3′-5′ ligation during splicing. They play an important role in the regulation of transcription and miRNA in eukaryotes. Drought is one of the detrimental abiotic stresses that limit plant growth and productivity. How circRNAs influence the response to drought stress in moso bamboo (Phyllostachys edulis) remains elusive. In this study, we investigate the expression pattern of circRNAs in moso bamboo at 6 h, 12 h, 24 h and 48 h after drought treatment by deep sequencing and bioinformatics analysis and identify 4931 circRNAs, 52 of which are differentially expressed (DEcircRNAs) in drought-treated and untreated moso bamboo. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses of the host genes that generate the DEcircRNAs indcate that these DEcircRNAs are predicted to be involved in biochemical processes in response to drought, such as ubiquitin-mediated proteolysis, calcium-dependent protein kinase phosphorylation, amino acid biosynthesis and plant hormone signal transduction including abscisic acid. In addition, some circRNAs are shown to act as sponges for 291 miRNAs. Taken together, our results characterize the transcriptome profiles of circRNAs in drought responses and provide new insights into resistance breeding of moso bamboo.

Abstract
Bamboo, being an ornamental plant, has myriad aesthetic and economic significance. Particularly, Phyllostachys violascens cv. Viridisulcata contains an internode color phenotype in variation in green and yellow color between the sulcus and culm, respectively. This color variation is unique, but the underlying regulatory mechanism is still unknown. In this study, we used metabolomic and transcriptomic strategies to reveal the underlying mechanism of variation in internode color. A total of 81 metabolites were identified, and among those, prunin as a flavanone and rhoifolin as a flavone were discovered at a high level in the culm. We also found 424 differentially expressed genes and investigated three genes (PvGL, PvUF7GT, and PvC12RT1) that might be involved in prunin or rhoifolin biosynthesis. Their validation by qRT-PCR confirmed high transcript levels in the culm. The results revealed that PvGL, PvUF7GT, and PvC12RT1 might promote the accumulation of prunin and rhoifolin which were responsible for the variation in internode color of P. violascens. Our study also provides a glimpse into phenotypic coloration and is also a valuable resource for future studies.

Abstract
BACKGROUND The use of mulberry leaves has long been limited to raising silkworms, but with the continuous improvement of mulberry (Morus alba) resource development and utilization, various mulberry leaf extension products have emerged. However, the fresh leaves of mulberry trees have a specific window of time for picking and are susceptible to adverse factors, such as drought stress. Therefore, exploring the molecular mechanism by which mulberry trees resist drought stress and clarifying the regulatory network of the mulberry drought response is the focus of the current work. RESULTS In this study, natural and drought-treated mulberry grafted seedlings were used for transcriptomic and proteomic analyses (CK vs. DS9), aiming to clarify the molecular mechanism of the mulberry drought stress response. Through transcriptome and proteome sequencing, we identified 9889 DEGs and 1893 DEPs enriched in stress-responsive GO functional categories, such as signal transducer activity, antioxidant activity, and transcription regulator activity. KEGG enrichment analysis showed that a large number of codifferentially expressed genes were enriched in flavonoid biosynthesis pathways, hormone signalling pathways, lignin metabolism and other pathways. Through subsequent cooperation analysis, we identified 818 codifferentially expressed genes in the CK vs. DS9 comparison group, including peroxidase (POD), superoxide dismutase (SOD), aldehyde dehydrogenase (ALDHs), glutathione s-transferase (GST) and other genes closely related to the stress response. In addition, we determined that the mulberry gene MaWRKYIII8 (XP_010104968.1) underwent drought- and abscisic acid (ABA)-induced expression, indicating that it may play an important role in the mulberry response to drought stress. CONCLUSIONS Our research shows that mulberry can activate proline and ABA biosynthesis pathways and produce a large amount of proline and ABA, which improves the drought resistance of mulberry. MaWRKYIII8 was up-regulated and induced by drought and exogenous ABA, indicating that MaWRKYIII8 may be involved in the mulberry response to drought stress. These studies will help us to analyse the molecular mechanism underlying mulberry drought tolerance and provide important gene information and a theoretical basis for improving mulberry drought tolerance through molecular breeding in the future.

Abstract
Crop production is a serious challenge to provide food for the 10 billion individuals forecasted to live across the globe in 2050. The scientists' emphasize establishing an equilibrium among diversity and quality of crops by enhancing yield to fulfill the increasing demand for food supply sustainably. The exploitation of genetic resources using genomics and metabolomics strategies can help generate resilient plants against stressors in the future. The innovation of the next-generation sequencing (NGS) strategies laid the foundation to unveil various plants' genetic potential and help us to understand the domestication process to unmask the genetic potential among wild-type plants to utilize for crop improvement. Nowadays, NGS is generating massive genomic resources using wild-type and domesticated plants grown under normal and harsh environments to explore the stress regulatory factors and determine the key metabolites. Improved food nutritional value is also the key to eradicating malnutrition problems around the globe, which could be attained by employing the knowledge gained through NGS and metabolomics to achieve suitability in crop yield. Advanced technologies can further enhance our understanding in defining the strategy to obtain a specific phenotype of a crop. Integration among bioinformatic tools and molecular techniques, such as marker-assisted, QTLs mapping, creation of reference genome, de novo genome assembly, pan- and/or super-pan-genomes, etc., will boost breeding programs. The current article provides sequential progress in NGS technologies, a broad application of NGS, enhancement of genetic manipulation resources, and understanding the crop response to stress by producing plant metabolites. The NGS and metabolomics utilization in generating stress-tolerant plants/crops without deteriorating a natural ecosystem is considered a sustainable way to improve agriculture production. This highlighted knowledge also provides useful research that explores the suitable resources for agriculture sustainability.

Abstract
The U-box gene encodes a ubiquitin ligase that contains a U-box domain. The plant U-box (PUB) protein plays an important role in the plant stress response; however, very few studies have investigated the role of these proteins in Moso bamboo (Phyllostachys edulis). Thus, more research on PUB proteins is necessary to understand the mechanisms of stress tolerance in P. edulis. In this study, we identified 121 members of the PUB family in P. edulis (PePUB), using bioinformatics based on the P. edulis V2 genome build. The U-box genes of P. edulis showed an uneven distribution among the chromosomes. Phylogenetic analysis of the U-box genes between P. edulis and Arabidopsis thaliana suggested that these genes can be classified into eight subgroups (Groups I–VIII) based on their structural and phylogenetic features. All U-box genes and the structure of their encoded proteins were identified in P. edulis. We further investigated the expression pattern of PePUB genes in different tissues, including the leaves, panicles, rhizomes, roots, and shoots. The qRT-PCR results showed that expression of three genes, PePUB15, PePUB92, and PePUB120, was upregulated at low temperatures compared to that at 25°C. The expression levels of two PePUBs, PePUB60 and PePUB120, were upregulated under drought stress. These results suggest that the PePUB genes play an important role in resistance to low temperatures and drought in P. edulis. This research provides new insight into the function, diversity, and characterization of PUB genes in P. edulis and provides a basis for understanding their biological roles and molecular mechanisms.

Int J Mol Sci 2021; 22:ijms222312917. [PMID: 34884720 PMCID: PMC8657895 DOI: 10.3390/ijms222312917] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 11/21/2021] [Accepted: 11/26/2021] [Indexed: 11/16/2022] Open
Abstract
Lignin biosynthesis enzymes form complexes for metabolic channelling during lignification and these enzymes also play an essential role in biotic and abiotic stress response. Cinnamyl alcohol dehydrogenase (CAD) is a vital enzyme that catalyses the reduction of aldehydes to alcohols, which is the final step in the lignin biosynthesis pathway. In the present study, we identified 49 CAD enzymes in five Bambusoideae species and analysed their phylogenetic relationships and conserved domains. Expression analysis of Moso bamboo PheCAD genes in several developmental tissues and stages revealed that among the PheCAD genes, PheCAD2 has the highest expression level and is expressed in many tissues and PheCAD1, PheCAD6, PheCAD8 and PheCAD12 were also expressed in most of the tissues studied. Co-expression analysis identified that the PheCAD2 positively correlates with most lignin biosynthesis enzymes, indicating that PheCAD2 might be the key enzyme involved in lignin biosynthesis. Further, more than 35% of the co-expressed genes with PheCADs were involved in biotic or abiotic stress responses. Abiotic stress transcriptomic data (SA, ABA, drought, and salt) analysis identified that PheCAD2, PheCAD3 and PheCAD5 genes were highly upregulated, confirming their involvement in abiotic stress response. Through yeast two-hybrid analysis, we found that PheCAD1, PheCAD2 and PheCAD8 form homo-dimers. Interestingly, BiFC and pull-down experiments identified that these enzymes form both homo- and hetero- dimers. These data suggest that PheCAD genes are involved in abiotic stress response and PheCAD2 might be a key lignin biosynthesis pathway enzyme. Moreover, this is the first report to show that three PheCAD enzymes form complexes and that the formation of PheCAD homo- and hetero- dimers might be tissue specific.

[PMID: 34392380 DOI: 10.1007/s00299-021-02765-7] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 07/30/2021] [Indexed: 06/13/2023]
Abstract
PeTCP10 can be induced by salt stresses and play important regulation roles in salt stresses response in transgenic Arabidopsis. Salt stress is one of the major adverse environmental factors that affect normal plant development and growth. PeTCP10, a Class I TCP member, was markedly expressed in moso bamboo mature leaf, root and stem under normal conditions and also induced by salt stress. Overexpressed PeTCP10 was found to enhance salt tolerance of transgenic Arabidopsis at the vegetative growth stage. It was also found capable to increase relative water content, while decreasing relative electrolyte leakage and Na+ accumulation of transgenic Arabidopsis versus wild-type (WT) plants at high-salt conditions. In addition, it improved antioxidant capacity of transgenic Arabidopsis plants by promoting catalase activity and enhanced their H2O2 tolerance. In contrast to WT plants, transcriptome analysis demonstrated that multiple genes related to abscisic acid, salt and H2O2 response were induced after NaCl treatment in transgenic plants. Meanwhile, overexpressed PeTCP10 improved the tolerance of abscisic acid. Moreover, luciferase reporter assay results showed that PeTCP10 is able to directly activate the expression of BT2 in transgenic plants. In contrary, the germination rates of transgenic plants were significantly lower than those of WT plants under high-NaCl conditions. Both primary root length and survival rate at the seedling stage are also found lower in transgenic plants than in WT plants. It is concluded that overexpressed PeTCP10 enhances salt stress tolerance of transgenic plants at the vegetative growth stage, and it also improves salt sensitiveness in both germination and seedling stages. These research results will contribute to further understand the functions of TCPs in abiotic stress response.
