Summary

Understanding stress tolerance in plants plays a pivotal role in apprehending the metabolism (both primary and secondary), one of the prerequisites for improving plant quality and productivity. On one hand, a deficient supply of any nutrient limits the plant growth and development while on the other various biotic as well as abiotic stress factors impose a negative impact on the productivity of the plant yield. To deal with these stresses, plants have developed different strategies determining the massive flexibility of plant metabolism, encompassing morphological, anatomical, biochemical, and physiological processes. With the advent of modern omics tools, the deeper molecular networks and regulatory mechanisms involving a myriad of transcripts, proteins, and metabolites have been unravelled in plants under various stresses. This special issue intends to integrate recent omics approaches such as phenomics, genomics, epigenomics, metagenomics, transcriptomics, proteomics, hormonomics, metabolomics, Ionomics, fluxomics, physiomics, lipidomics, glycomics, cytomics, volatilomics, and interactomics, to allow for a detailed picture of how different plants react to the stresses and develops tolerance. These gain novel molecular insights as an integrated system entailed for devising future strategies to improve crop yield.

    4-Hydroxy-2-Oxoglutaric Acid, A Key Metabolite Involved in Trypsin-Regulation of Arginine Metabolism in Hylocereus undatus during Storage

    Bairu Li, Jingyu Jia, Hemin Wang, Jiaju Sun, Enyan Chen, Xin Li
    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 885-900, 2024, DOI:10.32604/phyton.2024.050450

    Abstract Trypsin, a novel superoxide scavenger, significantly enhances the storage quality of Hylocereus undatus (H. undatus). To elucidate the preservation mechanism of trypsin on H. undatus, a widely targeted metabolomic analysis, and transcriptomics analysis were conducted. Firstly, a total of 453 metabolites were identified, with organic acids and their derivatives constituting the largest proportion (25%). Amino acids and their metabolites, prominent among organic acids, were further analyzed. Among them, 73 metabolites were associated with amino acids, and 37 exhibited significant differences. The most enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway was arginine biosynthesis (map00220), with polyamine metabolites… More >

    ShCTR1 Interacts with ShRBOH1 to Positively Regulate Aerenchyma Formation in Saussurea inversa through ROS Mediation

    Wubin Dai, Xiuting Ju, Guomin Shi, Jialei Guo, Tao He
    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 1023-1042, 2024, DOI:10.32604/phyton.2024.050066

    Abstract Saussurea inversa is one of the Tibetan medicine with developed aerenchyma. In this study, we investigated the function of the ShCTR1 gene related to the formation of aerenchyma. The study of the occurrence and formation of aerenchyma in S. inversa has certain theoretical significance in revealing the special mechanism of alpine plants adapting to the environment. The results of yeast two-hybrid experiments showed that S. inversa ShCTR1 interacted with the ShRBOH1, which is a key producer of reactive oxygen species (ROS), and it was hypothesized that ShCTR1 regulation of aerenchyma formation in S. inversa mainly mediated by ROS. Aerenchyma induction and… More >

    Response Mechanisms to Flooding Stress in Mulberry Revealed by Multi-Omics Analysis

    Jingtao Hu, Wenjing Chen, Yanyan Duan, Yingjing Ru, Wenqing Cao, Pingwei Xiang, Chengzhi Huang, Li Zhang, Jingsheng Chen, Liping Gan
    Phyton-International Journal of Experimental Botany, Vol.93, No.2, pp. 227-245, 2024, DOI:10.32604/phyton.2024.046521

    Abstract Abiotic stress, including flooding, seriously affects the normal growth and development of plants. Mulberry (Morus alba), a species known for its flood resistance, is cultivated worldwide for economic purposes. The transcriptomic analysis has identified numerous differentially expressed genes (DEGs) involved in submergence tolerance in mulberry plants. However, a comprehensive analyses of metabolite types and changes under flooding stress in mulberry remain unreported. A non-targeted metabolomic analysis utilizing liquid chromatography-tandem mass spectrometry (LC-MS/MS) was conducted to further investigate the effects of flooding stress on mulberry. A total of 1,169 metabolites were identified, with 331 differentially accumulated metabolites… More >

    Abstract

    Abiotic stresses, including drought, have been found to affect the growth and medicinal quality of numerous herbs. The proposed study aims to study the effects of different drought regimes on the metabolic profile, growth, ecophysiology, cellular antioxidants, and antioxidant potential of Nigella sativa (Black cumin) leaf. Forty-day-old seedlings of N. sativa were exposed to three regimes of drought (control, moderate and high) for a week. UPLC-MS/MS metabolic profile of the leaf reveals the presence of more than a hundred metabolites belonging to anthocyanins, chalcones, dihydro flavonoids, flavonoids, flavanols, flavones, flavonoid carbonoside, isoflavones, etc. Drought was found to

    Abstract Hot pepper (Capsicum annuum L.) is consumed as one of the oldest domesticated crops all over the world. Although mutation breeding using radiation has been performed in hot peppers, little is known about the comparative analysis of mutagenic effects at the molecular level by ion beam irradiation. To comprehend the response mechanism of hot pepper to the ion beam, we used a mutant with favorable economic characteristics induced by lithium-ion beam irradiation to investigate the biological effects. The results indicated that the lithium-ion beam had a positive effect on important agronomic traits, particularly yield unit, but… More >
