Autotoxicity in plants limits their growth and that of nearby plants of the same species, which has obvious implications in crop yield and quality. Silicon (Si) has been shown to increase plant tolerance to autotoxic stress. However, the physiological mechanisms underlying the effects of Si in alleviating autotoxicity during germination in cucumber (Cucumis sativus L.) are unknown. Cinnamic acid derivatives, such as 3-phenylpropionic acid (PA), are a class of autotoxins present in cucumber root exudates. Our objective was to investigate Si-induced autotoxic stress tolerance in cucumber seedlings by focusing on the effects of Si on the induction of antioxidant defense pathways. We found that PA treatment significantly reduced seed germination, radicle length, lateral root number, fresh weight, AsA and GSH contents, and the activities of SOD, CAT, and APX in cucumber seedlings, while it increased membrane permeability and levels of MDA, proline, O 2 - , and H2O2. Application of Si enhanced growth of PA-treated plants and significantly increased germination rate, radicle length, lateral root number, fresh weight, AsA and GSH levels, and SOD, CAT, POD, and APX activities. These results suggest that exogenous Si alleviates autotoxicity caused by PA during seed germination by increasing antioxidant enzyme activities and mitigating lipid peroxidation.

Salt stress as one of main abiotic stresses damaged plant growth and development. In this study, the effects of ethylene on Ca2+-regulated rooting index, Na+ and K+ concentration, Na+ transportation and cell ultrastructure during adventitious rooting in cucumber (Cucumis sativus L.) under salt stress were investigated. The results showed that ethylene might play a positive role in Ca2+-regulated rooting index during adventitious rooting under salt stress. Moreover, CaCl2 treatment significantly decreased the intracellular Na+ level but increased K+ content of cucumber explants under salt stress. However, the Na+ and K+ concentration which treated with Ca2+ treatment was significantly influenced by ethylene inhibitors under salt stress. Our results also showed that ethylene might be involved in Ca2+-affected cell ultrastructure of cucumber explants under salt condition. Further analysis showed that ethylene might be responsible for Ca2+-regulated Na+ transport through enhancing the transcriptional and protein levels of Na+/H+ antiporter as well as H+-ATPase for alleviating the negative effects of NaCl stress. Therefore, ethylene might act as a downstream signaling molecule of Ca2+ to maintain Na+ and K+ homeostasis via regulating Na+ transport and preserve the integrity of cellular ultrastructure of cucumber explant during adventitious rooting under salt condition.

Objective: With the rapid development of proteomics sequencing and RNA sequencing technology, multi-omics analysis has become a current research hotspot. Our previous study indicated that Xinjiang brown cattle have better meat quality than Kazakh cattle. In this study, Xinjiang brown cattle and Kazakh cattle were used as the research objects. Methods: Proteome sequencing and RNA sequencing technology were used to analyze the proteome and transcriptome of the longissimus dorsi muscle of the two breeds of adult steers (n = 3). Results: In this project, 22,677 transcripts and 1,874 proteins were identified through quantitative analysis of the transcriptome and proteome. By comparing the identified transcriptome and proteome, we found that 1,737 genes were identified at both the transcriptome and proteome levels. The results of the study revealed 12 differentially expressed genes and proteins: troponin I1, crystallin alpha B, cysteine, and glycine rich protein 3, phosphotriesterase-related, myosin-binding protein H, glutathione s-transferase mu 3, myosin light chain 3, nidogen 2, dihydropyrimidinase like 2, glutamate-oxaloacetic transaminase 1, receptor accessory protein 5, and aspartoacylase. We performed functional enrichment of these differentially expressed genes and proteins. The Kyoto encyclopedia of genes and genomes results showed that these differentially expressed genes and proteins are enriched in the fatty acid degradation and histidine metabolism signaling pathways. We performed parallel reaction monitoring (PRM) verification of the differentially expressed proteins, and the PRM results were consistent with the sequencing results. Conclusion: Our study provided and identified the differentially expressed genes and proteins. In addition, identifying functional genes and proteins with important breeding value will provide genetic resources and technical support for the breeding and industrialization of new genetically modified beef cattle breeds.
