Abstract :
【目的】分析土壤含水量对玫瑰茄萼片花青素含量以及二氢黄酮醇-4-还原酶(DFR)基因表达水平的影响,为玫瑰茄栽培时的水分管理以及进一步明确DFR基因在花青素合成中的功能提供参考。【方法】以玫瑰茄品种‘广东早熟’为试验材料,分别设置了33%(极度干旱)、55%(轻度干旱)、80%(渍涝)3个土壤含水量处理,分别测定各处理下开花后10(前期)、20(中期)、30 d(后期)玫瑰茄萼片中花青素的含量以及5个DFR基因的表达量,并对花青素含量与DFR基因表达量的相关性进行了分析。【结果】(1)不同土壤含水量下,随着开花时间的推移,玫瑰茄萼片花青素含量均呈下降趋势,且开花前期与开花后期的差异显著;含水量为80%时,花青素含量下降幅度最大;开花前、中期,土壤含水量为33%的花青素含量明显低于土壤含水量为55%、80%的含量;开花后期,3个土壤含水量处理的花青素含量差异不显著。(2)不同土壤含水量下,DFR基因的表达量随着开花时间的推移呈现不同的变化趋势。土壤含水量为33%时,5个DFR基因的表达量高于其他两个含水量处理,且在开花后30 d显著上调,达到最高值,其中,DFR4表达量最高,DFR5表达量最低;土壤含水量为55%、80%时,5个DFR基因的表达量均较低。(3)土壤含水量为55%时,DFR4、DFR5表达量与花青素含量显著相关,表明其为调控花青素合成的关键基因。【结论】严重的干旱和渍涝都不利于玫瑰茄萼片花青素的合成;干旱胁迫促进了DFR基因的表达,而渍涝情况下DFR基因的表达受到了抑制;DFR4、DFR5基因为调控玫瑰茄花青素合成的关键基因。

Abstract :
Cannabinoids, the bioactive compounds unique to Cannabis plants, demonstrate significant therapeutic potential in treating epilepsy, pain management, and inflammatory conditions. Despite their clinical importance, the genetic mechanisms underlying cannabinoid biosynthesis in seed hemp remain poorly understood. Our study systematically identified 25 key genes involved in the cannabinoid synthesis pathway within the seed hemp genome. Comprehensive bioinformatics analyses were conducted to characterize their physicochemical properties, evolutionary relationships, gene structures, promoter cis-elements, and expression patterns. Transcriptomic profiling of 'Yushe' cultivar revealed tissue-specific expression patterns across roots, stems, leaves, and male/female flowers. These genes were organized into four distinct biosynthetic pathways: MEP (methylerythritol phosphate), GPP (geranyl diphosphate), acetic acid, and cannabinoid-specific pathways. Promoter analysis identified critical cis-elements associated with light responsiveness, phytohormone signaling, and stress adaptation. Notably, seven genes (CsaDXS, CsaHDS, CsaHDR, CsaGPP(lsu), CsaHPL, CsaTHCAS, CsaCBDAS) exhibited higher expression in male leaves, while four genes (CsaDXR, CsaGPP(lsu), CsaHPL, CsaCBDAS) were upregulated in female flowers. Comparative genomic analysis revealed that medicinal cannabis types possessed higher gene copy numbers for CsaDXS, CsaHDS, CsaTHCAS, and CsaCBDAS, which may account for their elevated cannabinoid production. Functional validation through VIGS-mediated silencing of PT gene demonstrated significant downregulation of THCAS and CBDAS expression. This study provides crucial genetic resources for functional characterization of cannabinoid synthase genes and facilitates the rational utilization of seed hemp germplasm.

Abstract :
Salt stress is a major global challenge that significantly hinders plant growth and reduces crop yields. Kenaf (Hibiscus cannabinus L.) is a valuable stem fiber crop increasingly cultivated in saline and alkaline soils. However, the molecular basis of kenaf's tolerance to saline stress during the germination phase of seeds has remained largely unexplored. In this study, we performed a comprehensive transcriptomic analysis on two contrasting kenaf cultivars, Fuhong 952 (salt-tolerant) and Zanyin No. 1 (salt-sensitive), under salt stress conditions during seed germination. The results revealed a total of 9,232 and 13,982 differentially expressed genes (DEGs) in Fuhong 952 and Zanyin No. 1, respectively, with the number of DEGs increasing with the duration of salt treatment. Hierarchical clustering of DEGs in both cultivars across various time points (3, 24, and 72 h) identified distinct co-expressed gene clusters corresponding to different phases of the salt stress response. The identified DEGs were implicated in maintaining ionic and membrane homeostasis and transcriptional regulation in salt stress responses. The verification of twelve DEGs through qRT-PCR confirmed the reliability of our RNA-sequencing data. Furthermore, virus-induced gene silencing of a salt-responsive gene HcWRKY70 resulted in a 36.90% decrease in plant height, a 2.3-fold elevation in Malondialdehyde (MDA) levels, and a 43.70% reduction in Catalase (CAT) activity under salt stress, suggesting that HcWRKY70 plays a crucial role in regulating both growth and oxidative stress responses in kenaf. Overall, this study elucidates significant understandings regarding the molecular mechanisms underlying salinity stress tolerance in kenaf. The identified genes, including HcWRKY70, could serve as valuable targets for breeding salt-tolerant kenaf cultivars by modulating key stress-responsive pathways and enhancing tolerance traits.

Abstract :
U6启动子是CRISPR/Cas9体系中驱动单向导RNA (single guide RNA, sgRNA)转录的重要元件,内源U6启动子相比外源U6启动子通常具有更高的启动效率。然而,目前黄麻内源U6启动子的研究还尚未见报道。本研究利用拟南芥保守的sgRNA AtU6-26序列,从黄麻“梅峰4号”基因组中克隆到相似性最高的CcU6.1与CcU6.3两个候选启动子。通过构建CcU6.1与CcU6.3分别驱动GUS报告基因的融合表达载体,利用农杆菌介导的转化法分别转染本氏烟草叶片和黄麻毛状根,通过GUS组织化学染色分析启动子的转录活性。同源比对结果显示,CcU6.1与CcU6.3启动子均具有影响U6启动子转录活性的2个必要元件USE和TATAbox。GUS组织化学染色表明,黄麻这2个U6启动子均具有转录活性,但在烟草叶片和黄麻毛状根中CcU6.1启动子的转录活性均弱于CcU6.3启动子,荧光定量PCR进一步验证了这一结果。考虑到过长的U6启动子可能会削弱其转录活性,于是比较分析CcU6.3与AtU6-26启动子的顺式作用元件,发现CcU6.3启动子5′端截短后的序列即从转录起始位点至–550bp位置,可能会进一步提高其转录活性。本研究率先在黄麻中克隆到具有较高转录活性的U6启动子CcU6.3,为构建黄麻属CRISPR/Cas9基因编辑系统提供了应用潜力的启动子。

Abstract :
The ARF (Auxin response factor), GH3 (Gretchen Hagen 3), and Aux/IAA (Auxin/indole-3-acetic acid) gene families are key components in auxin signaling pathway and function as regulators of growth in plants. However, this research is rarely reported in jute, which severely limits the understandings of mechanisms involved in fiber development. In this study, 13 ARF, 12 GH3 and 20 Aux/IAA putative genes were identified in the whole genome of jute. Exon-intron structures revealed the high conservation among these auxin-related gene family members. Chromosomal localization and synteny analysis showed that segmental duplication contributed to the expansion of CcARF, CcGH3 and CcIAA gene families. Phylogenetic and conserved motif analysis revealed that they have distinct functional and CcARF, CcGH3 and CcIAA-specific domains, respectively. The expression pattern analysis based on RNA-seq and qRT-PCR indicated that 7 CcARF, 5 CcGH3, and 14 CcIAA genes showed higher expression in stem barks than leaves at the vigorous vegetative growth stage in an elite cultivar Huangma 179 with normal plant height, respectively, suggesting they might regulate the development of bast fiber. Moreover, the expression of 5 CcARF, 4 CcGH3, and 12 CcIAA genes was differentially expressed in stem barks of a typical GA(3) sensitive dwarf germplasm in comparison to Huangma 179. The cis-element analysis showed that promoters of 4 CcARF, 3 CcGH3, and 7 CcIAA genes had 1 to 3 cis-elements involved in gibberellin-responsiveness, giving a hint that they could respond to endogenous gibberellin accumulation in Huangma 179 and form a complicated network to regulate hormone regulatory network and plant height. This study provides useful information for functional analysis of ARF, GH3, and Aux/IAA genes, which would be taken as candidates for genetic improvement of bast fiber quality in jute.

Abstract :
Protein phosphatase 2 C (PP2C) gene family is known for regulating a variety of abiotic stresses in plants. However, little is currently understood about this gene family in jute. In this study, a total of 60 CcPP2C genes were identified in jute, which were named from CcPP2C1 to CcPP2C60 according to the order of their physical coordinates. These CcPP2C proteins contained about 162-1324 amimo acids. Their isoelectric points varied in the range of 4.51-9.45, and their molecular weights varied from 18.307 to 146.906 kDa. The evolutionary tree of PP2Cs in jute and Arabidopsis indicated that PP2Cs can be divided into 12 branches. Sixty-seven collinear gene pairs were identified between 42 CcPP2Cs and 62 AtPP2Cs by analyzing the whole genome collinearity data of jute and Arabidopsis. The analyses of conserved motifs in these CcPP2C proteins and cis-elements in the promoters revealed that CcPP2Cs might play an extensive role in responses to various abiotic stresses in jute. Particularly, the expression patterns of CcPP2Cs in group A under salt treatments showed that CcPP2C51 was up-regulated under various stress treatments. And CcPP2C51 was localized in the nucleus and cell membrane. In Arabidopsis, the overexpression of CcPP2C51 positively regulated the salt-tolerance genes. Also, the overexpression of CcPP2C51 improved the salt tolerance of jute regenerated roots. This study revealed the origin and evolution of PP2C genes in jute, and provides potential possibilities for molecular breeding of jute.

Abstract :
BackgroundSatellite repeats are one of the most rapidly evolving components in eukaryotic genomes and play vital roles in genome regulation, genome evolution, and speciation. As a consequence, the composition, abundance and chromosome distribution of satellite repeats often exhibit variability across various species, genome, and even individual chromosomes. However, we know little about the satellite repeat evolution in allopolyploid genomes. ResultsIn this study, we investigated the satellite repeat signature in five okra (Abelmoschus esculentus) accessions using genomic and cytogenetic methods. In each of the five accessions, we identified eight satellite repeats, which exhibited a significant level of intraspecific conservation. Through fluorescence in situ hybridization (FISH) experiments, we observed that the satellite repeats generated multiple signals and exhibited variations in copy number across chromosomes. Intriguingly, we found that five satellite repeats were interspersed with centromeric retrotransposons, signifying their involvement in centromeric satellite repeat identity. We confirmed subgenome-biased amplification patterns of these satellite repeats through existing genome assemblies or dual-color FISH, indicating their distinct dynamic evolution in the allotetraploid okra subgenome. Moreover, we observed the presence of multiple chromosomes harboring the 35 S rDNA loci, alongside another chromosomal pair carrying the 5 S rDNA loci in okra using FISH assay. Remarkably, the intensity of 35 S rDNA hybridization signals varied among chromosomes, with the signals predominantly localized within regions of relatively weak DAPI staining, associated with GC-rich heterochromatin regions. Finally, we observed a similar localization pattern between 35 S rDNA and three satellite repeats with high GC content and confirmed their origin in the intergenic spacer region of the 35 S rDNA. ConclusionsOur findings uncover a unique satellite repeat signature in the allotetraploid okra, contributing to our understanding of the composition, abundance, and chromosomal distribution of satellite repeats in allopolyploid genomes, further enriching our understanding of their evolutionary dynamics in complex allopolyploid genomes.

Abstract :
Jute (Corchorus capsularis L.) is the second most important natural plant fiber source after cotton. However, developing an efficient gene editing system for jute remains a challenge. In this study, the transgenic hairy root system mediated by Agrobacterium rhizogenes strain K599 was developed for Meifeng 4, an elite jute variety widely cultivated in China. The transgenic hairy root system for jute was verified by subcellular localization and bimolecular fluorescence complementation (BiFC) assays. The CHLOROPLASTOS ALTERADOS 1 (CcCLA1) gene, which is involved in the development of chloroplasts, was targeted for editing at two sites in Meifeng 4. Based on this hairy root transformation, the gRNA scaffold was placed under the control of cotton ubiquitin GhU6.7 and -GhU6.9 promoters, respectively, to assess the efficiency of gene editing. Results indicated the 50.0% (GhU6.7) and 38.5% (GhU6.9) editing events in the target 2 alleles (gRNA2), but no mutation was detected in the target 1 allele (gRNA1) in transgenic-positive hairy roots. CcCLA1 gene editing at gRNA2 under the control of GhU6.7 in Meifeng 4 was also carried out by Agrobacterium tumefaciens-mediated transformation. Two CcCLA1 mutants were albinic, with a gene editing efficiency of 5.3%. These findings confirm that the CRISPR/Cas9 system, incorporating promoter GhU6.7, can be used as a gene editing tool for jute.

Abstract :
Plant height (PH) is an important factor affecting bast fiber yield in jute. Here, we report the mechanism of dwarfism in the 'Guangbaai' (gba) of jute. The mutant gba had shorter internode length and cell length compared to the standard cultivar 'TaiZi 4' (TZ4). Exogenous GA(3) treatment indicated that gba is a GA-insensitive dwarf mutant. Quantitative trait locus (QTL) analysis of three PH-related traits via a high-density genetic linkage map according to re-seq showed that a total of 25 QTLs were identified, including 13 QTLs for PH, with phenotypic variation explained ranging from 2.42 to 74.16%. Notably, the functional mechanism of the candidate gene CoGID1a, the gibberellic acid receptor, of the major locus qPHIL5 was evaluated by transgenic analysis and virus-induced gene silencing. A dwarf phenotype-related single nucleotide mutation in CoGID1a was identified in gba, which was also unique to the dwarf phenotype of gba among 57 cultivars. Cogid1a was unable to interact with the growth-repressor DELLA even in the presence of highly accumulated gibberellins in gba. Differentially expressed genes between transcriptomes of gba and TZ4 after GA(3) treatment indicated up-regulation of genes involved in gibberellin and cellulose synthesis in gba. Interestingly, it was found that up-regulation of CoMYB46, a key transcription factor in the secondary cell wall, by the highly accumulated gibberellins in gba promoted the expression of cellulose synthase genes CoCesA4 and CoCesA7. These findings provide valuable insights into fiber development affected by endogenous gibberellin accumulation in plants.
