Abstract :

Plant chitinase is a pathogenesis-related protein that can hydrolyze chitin, the main component of fungal cell walls, and plays an important role in plant disease defense responses. Our previous study found the sugarcane class IV chitinase gene ScChiIV1 (GenBank Accession No. KP165001) was responding positively to smut pathogen Sporisorium scitamineum stress, but its disease resistance function and mechanism were unclear. Here, the upstream promoter of the ScChiIV1 gene (pro-ScChiIV1) with a length of 1696 bp was cloned which contained cis- acting elements related to hormone and stress response. Transient overexpression of the pro-ScChiIV1 in Nicotiana benthamiana showed inducible transcriptional levels by ABA, Fusarium solani var. coeruleum, and Alternaria longipes stimuli. Furthermore, stable overexpression of the ScChiIV1 gene in N. benthamiana enhanced the resistance of transgenic plants against F. solani var. coeruleum and S. scitamineum. Phenotypic monitoring, relevant physiological indicators, immune-related gene expression, and transcriptome analyses revealed that ScChiIV1 may activate potential TFs and PKs by inducing Ca2+ influx, ROS generation, and MAPK activation, thereby increasing the expression level of genes related to hormone signaling pathways, hypersensitive response (HR), and reactive oxygen species (ROS), as well as the activities of chitinase, superoxide dismutase (SOD), and catalase (CAT). In addition, ScChiIV1 reduced the contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) in transgenic plants, ultimately increasing disease resistance. This study provides novel insights into the molecular mechanism of the early response of the ScChiIV1 gene to pathogen stress and offers an excellent genetic resource for sugarcane disease resistant breeding.

Abstract :

甘蔗(Saccharum spp.)是重要的糖料作物,病害、寒害、干旱等生物和非生物胁迫是限制甘蔗生产的重要环境因素。β-1,3-葡聚糖酶(β-1,3-glucanase, EC 3.2.1.39)作为病程相关蛋白家族的一员,不仅在植物对病原菌的防御中发挥重要作用,还参与调控植物的生长发育和非生物逆境应答。为了系统性研究甘蔗β-1,3-葡聚糖酶基因家族,本研究从甘蔗野生种割手密‘Np-X’、热带种‘LA-Purple’和栽培种‘R570’基因组中鉴定到132个糖苷水解酶(glycoside hydrolase, GH) 17家族成员。通过进化树分析,这些成员被划分为4个亚家族,其中亚家族Ⅳ占比最大(102个)。甘蔗GH17家族包含5个保守基序,内含子数量介于0–16之间,且多为全基因组复制类型(割手密‘Np-X’和热带种‘LA-Purple’占89.50%),而栽培种‘R570’则以分散型复制为主(占58.10%)。启动子分析发现4类顺式作用元件,涉及植物生长发育及组织特异性表达(14.21%)、光响应(38.24%)、生物或非生物胁迫响应(9.18%)和激素响应(38.37%),提示该基因家族参与植物的生长发育、激素响应和逆境应答。转录组和实时荧光定量PCR(quantitative real-time PCR, RT-qPCR)分析结果表明,甘蔗GH17基因存在组织特异性表达,且在低温、干旱、激素处理以及不同甘蔗基因型与黑穗病菌互作过程中差异表达,提示其在植物防御机制中有一定潜在作用,某些SsGlu基因(SsGlu5、SsGlu20、SsGlu21、SsGlu25、SsGlu28、SsGlu39)有望作为候选抗逆相关基因。本研究为进一步揭示甘蔗β-1,3-葡聚糖酶基因家族的抗逆分子机制奠定了基础。

Abstract :

12-Oxo-phytodienoate reductase (OPR) is an oxidoreductase that depends on flavin mononucleotide (FMN) and catalyzes the conversion of 12-oxophytodienoate (12-OPDA) into jasmonic acid (JA). It plays a key role in plant growth and development, and resistance to adverse stresses. In our previous study, we have obtained an OPR gene (ScOPR1, GenBank Accession Number: MG755745) from sugarcane. This gene showed positive responses to methyl jasmonate (MeJA), salicylic acid (SA), abscisic acid (ABA), and Sporisorium scitamineum, suggesting its potential for pathogen resistance. Here, in our study, we observed that Nicotiana benthamiana leaves transiently overexpressing ScOPR1 exhibited weaker disease symptoms, darker 3,3-diaminobenzidine (DAB) staining, higher accumulation of reactive oxygen species (ROS), and higher expression of hypersensitive response (HR) and SA pathway-related genes after inoculation with Ralstonia solanacearum and Fusarium solanacearum var. coeruleum. Furthermore, the transgenic N. benthamiana plants stably overexpressing the ScOPR1 gene showed enhanced resistance to pathogen infection by increasing the accumulation of JA, SA, and glutathione S-transferase (GST), as well as up-regulating genes related to HR, JA, SA, and ROS signaling pathways. Transcriptome analysis revealed that the specific differentially expressed genes (DEGs) in ScOPR1-OE were significantly enriched in hormone transduction signaling and plant-pathogen interaction pathways. Finally, a functional mechanism model of the ScOPR1 gene in response to pathogen infection was depicted. This study provides insights into the molecular mechanism of ScOPR1 and presents compelling evidence supporting its positive involvement in enhancing plant disease resistance.

Molecular identification and functional characterization of a transcription factor GeRAV1 from Gelsemium elegans SCIE
期刊论文 | 2024 , 25 (1) | BMC GENOMICS
Abstract&Keyword Cite

Abstract :

BackgroundGelsemium elegans is a traditional Chinese medicinal plant and temperature is one of the key factors affecting its growth. RAV (related to ABI3/VP1) transcription factor plays multiple roles in higher plants, including the regulation of plant growth, development, and stress response. However, RAV transcription factor in G. elegans has not been reported.ResultsIn this study, three novel GeRAV genes (GeRAV1-GeRAV3) were identified from the transcriptome of G. elegans under low temperature stress. Phylogenetic analysis showed that GeRAV1-GeRAV3 proteins were clustered into groups II, IV, and V, respectively. RNA-sequencing (RNA-seq) and real-time quantitative PCR (qRT-PCR) analyses indicated that the expression of GeRAV1 and GeRAV2 was increased in response to cold stress. Furthermore, the GeRAV1 gene was successfully cloned from G. elegans leaf. It encoded a hydrophilic, unstable, and non-secretory protein that contained both AP2 and B3 domains. The amino acid sequence of GeRAV1 protein shared a high similarity of 81.97% with Camptotheca acuminata CaRAV. Subcellular localization and transcriptional self-activation experiments demonstrated that GeRAV1 was a nucleoprotein without self-activating activity. The GeRAV1 gene was constitutively expressed in the leaves, stems, and roots of the G. elegans, with the highest expression levels in roots. In addition, the expression of the GeRAV1 gene was rapidly up-regulated under abscisic acid (ABA), salicylic acid (SA), and methyl jasmonate (MeJA) stresses, suggesting that it may be involved in hormonal signaling pathways. Moreover, GeRAV1 conferred improved cold and sodium chloride tolerance in Escherichia coli Rosetta cells.ConclusionsThese findings provided a foundation for further understanding on the function and regulatory mechanism of the GeRAV1 gene in response to low-temperature stress in G. elegans.

Abstract :

钩吻(Gelsemium elegans)为马钱科钩吻属藤本植物,具有药用和禽畜饲用功效,但其在生长过程中易受低温危害的影响,因此挖掘低温响应基因对钩吻抗寒育种具有重要意义。乙烯响应因子(ethylene responsive factor, ERF)属于AP2/ERF转录因子超家族成员,在植物逆境胁迫应答反应中发挥关键作用。本研究基于钩吻转录组数据库挖掘到的响应低温胁迫的GeERF的unigene序列,利用逆转录聚合酶链式反应(reverse transcription-polymerase chain reaction, RT-PCR)技术从钩吻叶片克隆获得GeERF4B-1转录因子的cDNA全长序列。生物信息学分析表明,GeERF4B-1基因开放阅读框长度为759bp,编码252个氨基酸,蛋白相对分子量为27kDa,预测为不稳定的碱性亲水性蛋白。系统进化树分析结果显示,GeERF4B-1属于ERF家族的B-4亚族成员。亚细胞定位实验结果表明,GeERF4B-1定位在细胞核。实时荧光定量PCR(real time quantitative PCR, RT-qPCR)分析表明,GeERF4B-1基因在钩吻根、茎、叶中均有表达,在根中的表达量最高。经4℃低温、茉莉酸甲酯(methyl jasmonate,MeJA)和脱落酸(abscisic acid,ABA)处理后,相比于对照,GeERF4B-1基因均被诱导上调表达,分别在24 h或48 h达到峰值,表明该基因积极响应低温、MeJA和ABA胁迫;而氯化钠(sodium chloride,NaCl)和干旱处理后,GeERF4B-1基因均被诱导下调表达。此外,构建GeERF4B-1基因的原核表达载体,诱导获得大小约52kDa的融合蛋白。平板胁迫验证结果显示,与对照相比,转入GeERF4B-1的原核表达菌株能增强对低温的耐受性,但对盐胁迫和甘露醇胁迫较敏感。本研究为钩吻的抗逆性育种提供了潜在的基因资源和理论参考。

Abstract :

Associative nitrogen fixation contributes large portion of N input to agro-ecosystems through monocot-diazotrophic associations. However, the contribution of associative nitrogen fixation is usually neglected in modern agriculture, and the underlying mechanisms of association between monocot and diazotrophs remain elusive. Here, we demonstrated that monocot crops employ mucilage and associated benzoic acid to specially enrich diazotrophic partners in response to nitrogen deficiency, which could be used for enhancing associative nitrogen fixation in monocot crops. To be specific, mucilage and benzoic acid induced in sugarcane roots by nitrogen deficiency mediated enrichment of nitrogen-fixing Paraburkholderia through specific recruitment whereas other bacteria were simultaneously repelled. Further studies suggest maize employs a similar strategy in promoting associations with diazotrophs. In addition, our results also suggest that benzoic acid application significantly increases copy numbers of the nifH gene in soils and enhances associative nitrogen fixation in maize using 15N enrichment assay. Taken together, these results reveal a mechanism regulating the association between monocot crops and nitrogen-fixing bacteria, and, thereby point towards ways to harness these beneficial microbes in efforts to increase nitrogen efficiency in monocot crops through pathways regulated by a specific signaling molecule.

Characterization of the chitinase gene family in Saccharum reveals the disease resistance mechanism of ScChiVII1 SCIE

Abstract&Keyword Cite

Abstract :

Key messageA chitinase gene ScChiVII1 which is involved in defense against pathogen stress was characterized in sugarcane.AbstractChitinases, a subclass of pathogenesis-related proteins, catalyze chitin hydrolysis and play a key role in plant defense against chitin-containing pathogens. However, there is little research on disease resistance analysis of chitinase genes in sugarcane, and the systematic identification of their gene families has not been reported. In this study, 85 SsChi and 23 ShChi genes, which were divided into 6 groups, were identified from the wild sugarcane species Saccharum spontaneum and Saccharum hybrid cultivar R570, respectively. Transcriptome analysis and real-time quantitative PCR revealed that SsChi genes responded to smut pathogen stress. The chitinase crude extracted from the leaves of transgenic Nicotiana benthamiana plants overexpressing ScChiVII1 (a homologous gene of SsChi22a) inhibited the hyphal growth of Fusarium solani var. coeruleum and Sporisorium scitamineum. Notably, the chitinase and catalase activities and the jasmonic acid content in the leaves of ScChiVII1 transgenic N. benthamiana increased after inoculation with F solani var. coeruleum, but the salicylic acid, hydrogen peroxide, and malondialdehyde contents decreased. Comprehensive RNA sequencing of leaves before (0 day) and after inoculation (2 days) revealed that ScChiVII1 transgenic tobacco enhanced plant disease resistance by activating transcription factors and disease resistance-related signaling pathways, and modulating the expression of genes involved in the hypersensitive response and ethylene synthesis pathways. Taken together, this study provides comprehensive information on the chitinase gene family and offers potential genetic resources for disease resistance breeding in sugarcane.

Abstract&Keyword Cite

Abstract :

Gelsemium elegans is a traditional Chinese medicinal plant, with indole alkaloids as its main active ingredient. The plant can be used as medicine, mainly for pain relief, anti-inflammation and anti-tumor. Exogenous stress, such as low temperature, methyl jasmonate (MeJA), and salicylic acid (SA), can affect the growth of G. elegans and the synthesis of secondary metabolites. Under these conditions, there are only a few reports on the selection and validation of internal reference genes in G. elegans. In this study, seven candidate internal reference genes that showed stable expression abundance in the transcriptome database of G. elegans were selected. The stability and reliability of these genes were analyzed in different G. elegans tissues and under low temperature, MeJA, and SA stresses. The results showed that CUL was the optimal reference gene for expression analysis in different G. elegans tissues and under cold stress, SA stress, followed by eEF-1 alpha. Under MeJA stress, the best one was eEF-1 alpha, and the next was CUL. Furthermore, the expression patterns of three different G. elegans genes, including GPPS, ERF, and 60S, were carried out to confirm that single reference gene ( CUL or eEF-1 alpha) or double reference genes ( CUL + eEF-1 alpha) can be selected as the best or perfect combination of reference genes for gene expression analysis in G. elegans. This study lays a foundation for the accurate normalization and quantification of gene expression in G. elegans.

Abstract :

近年来,钩吻(Gelsemium elegans)的药用和饲用价值日益凸显,但钩吻在生长过程中不耐低温,挖掘其低温响应基因,为钩吻的抗寒育种研究奠定基础。植物中,脂氧合酶(lipoxygenase, LOX)在种子老化、抗逆境胁迫等方面的生理生化过程中有重要影响。基于课题组构建的钩吻转录组数据库,挖掘响应低温胁迫的钩吻LOX基因,运用RT-PCR技术,从中克隆到一条GeLOX1的cNDA全长序列,对其进行生物信息学、亚细胞定位、基因表达、原核表达及平板胁迫等分析。结果显示,GeLOX1所编码蛋白的氨基酸长度为761 aa,蛋白相对分子质量为87.00 kD,预测为不稳定的亲水性蛋白,含有28个丝氨酸磷酸化位点,22个苏氨酸磷酸化位点和9个酪氨酸磷酸化位点。进化树分析结果表明,GeLOX1属于9-LOX家族的成员。亚细胞定位检测结果显示,GeLOX1蛋白定位于细胞质中。实时荧光定量PCR分析发现,GeLOX1在钩吻的根中高表达,且其在4℃低温胁迫下的表达量呈现下调的趋势。经原核表达诱导后,GeLOX1的重组蛋白在约111 kD处出现目标条带,且重组蛋白的积累量在诱导8 h时达到峰值。此外,平板胁迫试验表明,GeLOX1的原核表达菌株相较于对照组对低温胁迫更敏感。钩吻GeLOX1能够应答低温胁迫。
