“…Then, in the Arabidopsis plants exposed to stilbenes and CA, we evaluated the expression of the stress-responsive genes ( Figure 5 ; Table S2 ), encoding transcriptional factors ( AtABI3 , 4 , 5 , AtCBF1 , AtDREB1A , 2A , RD26 ) [ 41 , 42 , 43 , 44 ], protein phosphatases ( AtABI1 , 2 ) [ 41 ], abscisic-binding factor ( AtABF ) [ 45 ], dehydrins ( AtCOR15 , 17 , AtRab18 , AtLEA ) [ 46 , 47 , 48 ], osmolyte synthases ( AtP5CS2 ) [ 49 ], antioxidant genes ( AtCAT , AtCSD1 , 2 ) [ 50 , 51 ], protein kinases ( AtKIN1 ) [ 52 ], lipid transfer proteins ( AtLtp ) [ 53 ], ion transporter genes ( AtNHX1 , AtSOS1 ) [ 54 , 55 ]. Also, several genes have no information on the physiological role, but it was shown that their expression strongly increased under stressful influences ( AtRD22 , 29a , 29b ) [ 56 , 57 ].…”

Stilbenes are a group of plant phenolic secondary metabolites, with trans-resveratrol (3,5,4′-trihydroxy-trans-stilbene) being recognized as the most prominent and studied member. Stilbenes have a great potential for use in agriculture and medicine, as they have significant activities against plant pathogens and have valuable beneficial effects on human health. In this study, we analyzed the effects of direct application of stilbenes, stilbene precursor, and stilbene-rich extract solutions to the plant foliar surface for increasing the resistance of Arabidopsis thaliana to various abiotic stresses (heat, cold, drought, and soil salinity). Exogenous treatment of A. thaliana with stilbenes (trans-resveratrol, piceid, and spruce bark extract) and phenolic precursor (p-coumaric acid or CA) during germination resulted in considerable growth retardation of A. thaliana plants: a strong delay in the root and stem length of 1-week-old seedlings (in 1.3–4.5 fold) and rosette diameter of 1-month-old plants (in 1.2–1.8 fold), while the 2-month-old treated plants were not significantly different in size from the control. Plant treatments with stilbenes and CA increased the resistance of A. thaliana to heat and, to a lesser extent, to soil salinity (only t-resveratrol and spruce extract) to drought (only CA), while cold resistance was not affected. Plant treatments with stilbenes and CA resulted in a significant increase in plant resistance and survival rates under heat, with plants showing 1.5–2.3 times higher survival rates compared to untreated plants. Thus, exogenous stilbenes and a CA are able to improve plant survival under certain abiotic stresses via specific activation of the genes involved in the biosynthesis of auxins, gibberellins, abscisic acid, and some stress-related genes. The present work provides new insights into the application of stilbenes to improve plant stress tolerance.

“…Signalling lipids such as fatty acids, sphingolipids, diacylglycerols, lysophospholipids, phosphatidic acid, inositol phosphate, oxylipins and N-acylethanolamine are quickly synthesized under stress conditions. Simultaneously, lipids are also involved in the remodelling of cell membranes under abiotic stress and mitigate cell damage [ 258 ]. Improvement of analytical methods, particularly liquid chromatography and mass spectrometry, enables systems-level analysis of lipids and their interacting partners [ 259 ].…”

The present day’s ongoing global warming and climate change adversely affect plants through imposing environmental (abiotic) stresses and disease pressure. The major abiotic factors such as drought, heat, cold, salinity, etc., hamper a plant’s innate growth and development, resulting in reduced yield and quality, with the possibility of undesired traits. In the 21st century, the advent of high-throughput sequencing tools, state-of-the-art biotechnological techniques and bioinformatic analyzing pipelines led to the easy characterization of plant traits for abiotic stress response and tolerance mechanisms by applying the ‘omics’ toolbox. Panomics pipeline including genomics, transcriptomics, proteomics, metabolomics, epigenomics, proteogenomics, interactomics, ionomics, phenomics, etc., have become very handy nowadays. This is important to produce climate-smart future crops with a proper understanding of the molecular mechanisms of abiotic stress responses by the plant’s genes, transcripts, proteins, epigenome, cellular metabolic circuits and resultant phenotype. Instead of mono-omics, two or more (hence ‘multi-omics’) integrated-omics approaches can decipher the plant’s abiotic stress tolerance response very well. Multi-omics-characterized plants can be used as potent genetic resources to incorporate into the future breeding program. For the practical utility of crop improvement, multi-omics approaches for particular abiotic stress tolerance can be combined with genome-assisted breeding (GAB) by being pyramided with improved crop yield, food quality and associated agronomic traits and can open a new era of omics-assisted breeding. Thus, multi-omics pipelines together are able to decipher molecular processes, biomarkers, targets for genetic engineering, regulatory networks and precision agriculture solutions for a crop’s variable abiotic stress tolerance to ensure food security under changing environmental circumstances.

“…Inner Mongolia is one of the primary bases for the production of potato seed and commercial potatoes in China. The annual rainfall is approximately 200–350 mm, and the region is arid and semiarid (du et al, 2013 ; Zhang, Li, et al, 2022 ). Drought stress is by far the most complex abiotic stress that affects plant development, survival, and crop productivity on a global scale (Ahuja et al, 2010 ).…”

Lipid transfer proteins (LTPs) are widely distributed in plants and play an important role in the response to stress. Potato (Solanum tuberosum L.) is sensitive to a lack of water, and drought stress is one of the limiting factors for its yield. Therefore, mining candidate functional genes for drought stress and creating new types of potato germplasm for drought resistance is an effective way to solve this problem. There are few reports on the LTP family in potato. In this study, 39 members of the potato LTP family were identified. They were located on seven chromosomes, and the amino acid sequences encoded ranged from 101 to 345 aa. All 39 family members contained introns and had exons that ranged from one to four. Conserved motif analysis of potato LTP transcription factors showed that 34 transcription factors contained Motif 2 and Motif 4, suggesting that they were conserved motifs of potato LTP.Compared with the LTP genes of homologous crops, the potato and tomato (Solanum lycopersicum L.) LTPs were the mostly closely related. The StLTP1 and StLTP7 genes were screened by quantitative reverse transcription PCR combined with potato transcriptome data to study their expression in tissues and the characteristics of their responses to drought stress. The results showed that StLTP1 and StLTP7 were upregulated in the roots, stems, and leaves after PEG 6000 stress. Taken together, our study provides comprehensive information on the potato LTP family that will help to develop a framework for further functional studies.expression analysis, genome-wide identification, LTP, potato) is one of the most important food crops and economic crops in China, and the amounts of its area and yield rank first in the world.
