Jute (Corchorus spp.), belonging to the Malvaceae family, is an important natural fiber crop, second only to cotton, and a multipurpose economic crop. Corchorus capsularis L. is one of the only two commercially cultivated species of jute. Gene expression is spatiotemporal and is influenced by many factors. Therefore, to understand the molecular mechanisms of tissue development, it is necessary to study tissue-specific gene expression and regulation. We used weighted gene coexpression network analysis, to predict the functional roles of gene coexpression modules and individual genes, including those underlying the development of different tissue types. Although several transcriptome studies have been conducted on C. capsularis, there have not yet been any systematic and comprehensive transcriptome analyses for this species. There was significant variation in gene expression between plant tissues. Comparative transcriptome analysis and weighted gene coexpression network analysis were performed for different C. capsularis tissues at different developmental stages. We identified numerous tissue-specific differentially expressed genes for each tissue, and 12 coexpression modules, comprising 126 to 4203 genes, associated with the development of various tissues. There was high consistency between the genes in modules related to tissues, and the candidate upregulated genes for each tissue. Further, a gene network including 21 genes directly regulated by transcription factor OMO55970.1 was discovered. Some of the genes, such as OMO55970.1, OMO51203.1, OMO50871.1, and OMO87663.1, directly involved in the development of stem bast tissue. We identified genes that were differentially expressed between tissues of the same developmental stage. Some genes were consistently up- or downregulated, depending on the developmental stage of each tissue. Further, we identified numerous coexpression modules and genes associated with the development of various tissues. These findings elucidate the molecular mechanisms underlying the development of each tissue, and will promote multipurpose molecular breeding in jute and other fiber crops.

黄麻（Corchorus capsularis L.）中的基因共表达网络分析和基因表达的组织特异性分析。

黄麻（Corchorus spp。）属于锦葵科，是一种重要的天然纤维作物，仅次于棉花，是一种多用途经济作物。荚膜Corcorrus capsularis L.是仅有的两种商业种植的黄麻种之一。基因表达是时空的，并且受许多因素影响。因此，要了解组织发育的分子机制，有必要研究组织特异性基因的表达和调控。我们使用加权基因共表达网络分析，以预测基因共表达模块和单个基因的功能作用，包括那些潜在于不同组织类型发展的基因。尽管已对荚膜梭菌进行了一些转录组研究，但尚未对该物种进行任何系统和全面的转录组分析。植物组织之间的基因表达存在显着差异。在不同的发育阶段对不同的荚膜梭菌进行了比较转录组分析和加权基因共表达网络分析。我们确定了每种组织的众多组织特异性差异表达基因，以及与各种组织的发育相关的12个共表达模块，包括126至4203个基因。与组织相关的模块中的基因与每种组织的候选上调基因之间具有高度一致性。此外，发现了包括21个直接受转录因子OMO55970.1调控的基因的基因网络。一些基因，例如OMO55970.1，OMO51203.1，OMO50871.1和OMO87663.1，直接参与茎韧皮组织的发育。我们确定了在相同发育阶段的组织之间差异表达的基因。根据每个组织的发育阶段，某些基因始终被上调或下调。此外，我们鉴定了许多与各种组织发育相关的共表达模块和基因。这些发现阐明了每种组织发育的分子机制，并将促进黄麻和其他纤维作物的多用途分子育种。
