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.

    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 (DAMs) exhibiting up-regulation in… 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 alter the contents… More >

    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 had a negligible effect… More >
