Drought is the most prominent limiting factor to crop productivity, posing a severe threat to food security. However, how plants respond to drought stress and post-drought recovery remains unclear. Therefore, this study determined the morphological and protein responses of banana plants (Musa acuminata cultivar Berangan) affected by drought stress, followed by water recovery. The results showed that drought significantly reduced the leaf area, plant height, fresh weight, stem circumference, leaf relative water content, chlorophyll contents, and root length of the bananas. In contrast, relative electrolyte leakage, proline, malondialdehyde (MDA) and hydrogen peroxide contents, and the activities of antioxidant enzymes, including catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), peroxidase, and superoxide dismutase, were induced in the drought-treated banana leaves. However, the relative water content, MDA and hydrogen peroxide contents, and antioxidant enzyme activities, including CAT, APX, and GR, were comparable with well-watered plants after water recovery. Changes in the protein content between well-watered, drought-stressed, and recovered banana plants were determined using tandem mass tags (TMT)-based quantitative proteomics. Of the 1,018 differentially abundant proteins, 274 were significantly changed. The identified proteins differing between the treatments were mainly related to carbohydrate, energy and amino acid metabolisms, genetic information processing, and secondary metabolite biosynthesis. Our data may assist in developing a complete proteome dataset which could be valuable for developing drought-tolerant bananas.

“…The decreased abundance of FNR in drought-stressed bananas probably induces cyclic electron ow, leading to increased ATP synthesis to combat drought stress (Gharechahi et al 2015). However, contradictory results have also been reported (Li et al, 2021), and the actual mechanisms remain to be elucidated.…”

“…Also, in developing wheat grains subjected to a heat phase, a rise in many minor HSP proteins, as well as HSP82 from the HSP90 family was detected in the endosperm ( Skylas et al, 2002 ; Majoul et al, 2004 ). Similarly, proteome analysis conjugated with physiological response in two maize varieties resistant to drought stress reported the role of HSP to be important in protecting plants from drought stress ( Li et al, 2021b ). Lately, Halder et al (2022) reviewed the role of proteomics for abiotic stress tolerance in wheat and presented a summary of proteomic studies on salinity, drought stress tolerance, and root system architecture conducted in the last decade.…”

Flax (Linum usitatissimum L.) or linseed is one of the important industrial crops grown all over the world for seed oil and fiber. Besides oil and fiber, flax offers a wide range of nutritional and therapeutic applications as a feed and food source owing to high amount of α-linolenic acid (omega-3 fatty acid), lignans, protein, minerals, and vitamins. Periodic losses caused by unpredictable environmental stresses such as drought, heat, salinity-alkalinity, and diseases pose a threat to meet the rising market demand. Furthermore, these abiotic and biotic stressors have a negative impact on biological diversity and quality of oil/fiber. Therefore, understanding the interaction of genetic and environmental factors in stress tolerance mechanism and identification of underlying genes for economically important traits is critical for flax improvement and sustainability. In recent technological era, numerous omics techniques such as genomics, transcriptomics, metabolomics, proteomics, phenomics, and ionomics have evolved. The advancements in sequencing technologies accelerated development of genomic resources which facilitated finer genetic mapping, quantitative trait loci (QTL) mapping, genome-wide association studies (GWAS), and genomic selection in major cereal and oilseed crops including flax. Extensive studies in the area of genomics and transcriptomics have been conducted post flax genome sequencing. Interestingly, research has been focused more for abiotic stresses tolerance compared to disease resistance in flax through transcriptomics, while the other areas of omics such as metabolomics, proteomics, ionomics, and phenomics are in the initial stages in flax and several key questions remain unanswered. Little has been explored in the integration of omic-scale data to explain complex genetic, physiological and biochemical basis of stress tolerance in flax. In this review, the current status of various omics approaches for elucidation of molecular pathways underlying abiotic and biotic stress tolerance in flax have been presented and the importance of integrated omics technologies in future research and breeding have been emphasized to ensure sustainable yield in challenging environments.

“…The phosphoproteomic analysis in maize revealed that serine/threonine protein phosphatase 2C (ZmPP2C26) altered the phosphorylation level of proteins involved in photosynthesis [ 102 ]. Furthermore, leaf proteins involved in redox homeostasis and the electron transport chain helped in drought tolerance [ 103 ]. The drought-tolerance mechanism in maize roots was attributed to proteins involved in stronger water-retention capacity, activation of antioxidant enzymes, strengthening of the cell wall, osmotic stabilization of the plasma membrane, effective recycling of amino acids, and improved lignification [ 104 ].…”

Food security is a major challenge in the present world due to erratic weather and climatic changes. Environmental stress negatively affects plant growth and development which leads to reduced crop yields. Technological advancements have caused remarkable improvements in crop-breeding programs. Proteins have an indispensable role in developing stress resilience and tolerance in crops. Genomic and biotechnological advancements have made the process of crop improvement more accurate and targeted. Proteomic studies provide the information required for such targeted approaches. The crosstalk among cellular components is being analyzed by subcellular proteomics. Additionally, the functional diversity of proteins is being unraveled by post-translational modifications during abiotic stress. The exploration of precise cellular responses and the networking among different cellular organelles help in the prediction of signaling pathways and protein–protein interactions. High-throughput mass-spectrometry-based protein studies are now possible due to incremental advancements in mass-spectrometry techniques, sample protocols, and bioinformatic tools as well as the increasing availability of plant genome sequence information for multiple species. In this review, the key role of proteomic analysis in identifying the abiotic-stress-responsive mechanisms in various crops was summarized. The development and availability of advanced computational tools were discussed in detail. The highly variable protein responses among different crops have provided a wide avenue for molecular-marker-assisted genetic buildup studies to develop smart, high-yielding, and stress-tolerant varieties to cope with food-security challenges.
