土壤盐分是一种主要的环境胁迫，通过限制植物的发育和生长来降低农业生产力。黄麻（Corchorus spp.）是一种重要的商业韧皮纤维作物，包括两个商业栽培品种：荚膜黄麻（Corchorus capsularis）和小黄麻（Corchorus olitorius）。我们对盐胁迫下的24份荚膜C.和C. olitorius样品进行了高通量转录组测序，发现127个共同差异表达基因（DEGs）；在根和叶组织中分别鉴定出4489个和492个共同基因。此外，在叶片、根或两个组织中分别检测到32、196和11个共同差异表达转录因子（DTFs）。在NY和YY中富集了几个基因本体（GO）术语。《京都基因与基因组百科全书》的分析显示，这两个物种都有大量的deg。脱落酸和细胞分裂素信号通路在NY和YY的叶片和根中分别富集约20度。Ca2+、丝裂原激活的蛋白激酶信号通路和氧化磷酸化途径也被发现与植物对盐胁迫的反应有关，这一点被两种植物的根中的DEGs所证明。这些结果为深入了解植物对盐胁迫的反应机制提供了依据，也为今后选育耐盐品种奠定了基础。
Soil salinity, a major environmental stress, reduces agricultural productivity by restricting plant development and growth. Jute (Corchorus spp.), a commercially important bast fiber crop, includes two commercially cultivated species, Corchorus capsularis and Corchorus olitorius. We conducted high-throughput transcriptome sequencing of 24 C. capsularis and C. olitorius samples under salt stress and found 127 common differentially expressed genes (DEGs); additionally, 4489 and 492 common DEGs were identified in the root and leaf tissues, respectively, of both Corchorus species. Further, 32, 196, and 11 common differentially expressed transcription factors (DTFs) were detected in the leaf, root, or both tissues, respectively. Several Gene Ontology (GO) terms were enriched in NY and YY. A Kyoto Encyclopedia of Genes and Genomes analysis revealed numerous DEGs in both species. Abscisic acid and cytokinin signal pathways enriched respectively about 20 DEGs in leaves and roots of both NY and YY. The Ca2+, mitogen-activated protein kinase signaling and oxidative phosphorylation pathways were also found to be related to the plant response to salt stress, as evidenced by the DEGs in the roots of both species. These results provide insight into salt stress response mechanisms in plants as well as a basis for future breeding of salt-tolerant cultivars.
