Project description:Allium mongolicum, a xerophytic industrial plant native to the Mongolian Plateau, demonstrates notable stress resistance, though its salt-alkali tolerance mechanisms remain poorly understood. This study integrates physiological assessments, transcriptomics, metabolomics, and full-length transcriptome analyses to uncover its adaptive mechanisms under salt-alkali stress.A comprehensive full-length transcriptome was constructed under these conditions, comprising 30,117 non-redundant genes, alongside significant trends observed in the activities of antioxidant enzymes and key enzymes in the phenylpropanoid pathway. Combined transcriptomic and metabolomic analyses identified key genes and metabolites in the phenylpropanoid pathway as central to salt-alkali tolerance. WGCNA further highlighted critical genes, such as AmCOMT1, AmHSP18, and AmPPL7, with functional validation of AmCOMT1 and AmHSP18 confirming transcriptome reliability. The salt tolerance function of AmCOMT1 has been validated through overexpression in plants, and the binding interaction with AmERF4 has also been confirmed.A proposed model suggests A. mongolicum mitigates salt-alkali stress via reactive oxygen species scavenging, osmotic regulation, and structural support, providing valuable insights for breeding salt-tolerant crops and enhancing its agricultural applications.

Project description:We present here a transcriptome dataset of millet seedling leaves based on RNA-seq technology. The purpose of this study was to mine the salt and alkali tolerance genes of millet and further explore the mechanism of salt and alkali tolerance of millet. We selected 18 representative samples and conducted in-depth sequencing using the latest sequencing platform to ensure the accuracy and reliability of the data.

Project description:Real-time quantitative PCR (RT–qPCR) is the favoured method for gene expression analysis in molecular biology due to its sensitivity, specificity, cost-effectiveness, and reproducibility. To obtain the accuracy and reliability of RT-qPCR, the use of reliable reference genes is inevitable. There were many reports about the physiological response of giant reed (Arundo donax L.) to abiotic stresses. However, there is little use in the validation of reference genes under different treatments. It still belongs to the blank that the research about selecting reference genes under salt and alkali. In this study, the expression stability of twenty-three candidate reference genes in leaves and roots were assessed under salt, drought, and alkali stresses using geNorm, NormFinder, BestKeeper, and Delta Ct algorithms. Our results showed that no one gene had an invariant expression under different conditions. For example, under drought stress, UPL3, UBC2, and APT1 were better reference genes in leaves, RPL5 and FPS2 were better in roots. Under alkali stress, GAPDH, APT1, and RPS5 were better reference genes in leaves; UPL3, ACT2, and SAMDC2 were better in roots. In addition, the expression of MSD1 was used to further confirm the validated reference genes under salt, drought, and alkali stresses. It was proved that the use of inappropriate reference genes in giant reed significantly altered the relative expression of target genes and even reversed the results. Consequently, our results provided guidelines for reference gene selection under salt, drought, and alkali stresses and a foundation for more accurate and widespread use of RT-qPCR in the giant reed.

Project description:Salt stress, especially saline-alkali stress, has seriously negative effect on citrus production. Ziyang xiangcheng (Citrus junos Sieb.) (Cj) has been reported as a saline-alkali stress and iron deficiency tolerant citrus rootstock. However, the molecular mechanism of its saline-alkali stress tolerance is still not clear. Two citrus rootstocks and one navel orange scion, Cj, Poncirus trifoliate (Poncirus trifoliata (L.) Raf.) (Pt) and ‘Lane Late’ navel orange (Citrus sinensis (L.) Osb.) (LL), were used in this study. The grafted materials Cj+LL and Pt+LL grown in calcareous soil were used to identify genes and pathways responsive to saline-alkali stress using RNA-seq. The seedlings of Cj and Pt grown in the solutions with different gradient pH value were used to perform a supplement experiment. Comprehensively analyzing the data of RNA-seq, physiology and biochemistry, agronomic traits and mineral elements of Cj+LL, Pt+LL, Cj and Pt, several candidate pathways and genes were identified to be highly regulated under saline-alkali stress. Here, we propose citrate is important for the tolerance to iron deficiency and the jasmonate (JA) biosynthesis and signal transduction pathway may play a crucial role in tolerance to saline-alkali stress in citrus by interacting with other plant hormones, calcium signaling, ROS scavenging system and lignin biosynthesis.

Project description:Here, we treated the model cyanobacterium Synechococcus elongatus PCC7942 with streptomycin, which selectively binds to bacterial ribosomes, at a concentration of 50 µg/mL and performed transcriptome analysis using RNA sequencing. In addition to antibiotic stress, we treated salt stress (0.4 M NaCl) and performed RNA sequencing analysis.
