“…All four cultivars were severely injured by salt stress, as indicated by the higher ROS level and the decreasing total chlorophyll content, carotenoid content, membrane stability, and RWC of the seedlings. Excessive ROS production leads to oxidative stress and damages the cell membrane, proteins, and chlorophyll, ultimately leading to cell death [42,43]. Salt stress also led to increases in the accumulation of proline and in the expression levels…”

“…Proline is an important osmolyte for osmotic adjustment in plants under stress conditions [47]. Proline accumulation represents an acclimation response to stress, as proline helps to balance osmotic pressure in the cell (cell turgor), bring ROS concentrations within normal ranges (preventing oxidative bursts), stabilize cellular membranes (minimizing electrolyte leakage), conserve energy, and protect macromolecules, resulting in improved stress tolerance [42][43][44]. Notably, Merah Kalimantan Selatan showed lower proline contents in haloprimed than in non-primed seedlings.…”

Unfavorable environmental conditions and climate change impose stress on plants, causing yield losses worldwide. The Indonesian pigmented rice (Oryza sativa L.) cultivars Cempo Ireng Pendek (black rice) and Merah Kalimantan Selatan (red rice) are becoming popular functional foods due to their high anthocyanin contents and have great potential for widespread cultivation. However, their ability to grow on marginal, high-salinity lands is limited. In this study, we investigated whether seed halopriming enhances salt tolerance in the two pigmented rice cultivars. The non-pigmented cultivars IR64, a salt-stress-sensitive cultivar, and INPARI 35, a salt tolerant, were used as control. We pre-treated seeds with a halopriming solution before germination and then exposed the plants to a salt stress of 150 mM NaCl at 21 days after germination using a hydroponic system in a greenhouse. Halopriming was able to mitigate the negative effects of salinity on plant growth, including suppressing reactive oxygen species accumulation, increasing the membrane stability index (up to two-fold), and maintaining photosynthetic pigment contents. Halopriming had different effects on the accumulation of proline, in different rice varieties: the proline content increased in IR64 and Cempo Ireng Pendek but decreased in INPARI 35 and Merah Kalimantan Selatan. Halopriming also had disparate effects in the expression of stress-related genes: OsMYB91 expression was positively correlated with salt treatment, whereas OsWRKY42 and OsWRKY70 expression was negatively correlated with this treatment. These findings highlighted the potential benefits of halopriming in salt-affected agro-ecosystems.

“…Seed priming with GB, is a promising approach to reduce the antagonistic effects of drought on seed germination as well as early seedling establishment of wheat [ 37 ]. Improved boll weight, leaf greenness, and membrane stability were observed in cotton ( Gossypium hirsutum L.) primed with GB under drought conditions [ 38 ]. Previous studies reported that exogenous application of GB in wheat increased grain yield and grain numbers per spike [ 39 ]; improved stress tolerance index, enhanced osmolytes accumulation, and increased relative water content [ 40 ]; increased net photosynthesis rate and maximum photochemical efficiency of PSII and higher antioxidative enzymes activities [ 11 ]; stabilized thylakoid membrane functions, suppressed chlorophyll degradation and enhanced Ca 2+ -ATPase and Hill reaction activities, improved growth and enhanced activities of SOD, CAT, and APX [ 41 ].…”

“…Preliminary reports concerning each priming method suggested significant improvement in seed germination, plant growth, and development under stress conditions (Al‐Humaid, 2002; Zheng, 2002; Ashraf and Foolad, 2005; Fariduddin et al, 2003). Positive effects of seed priming are mainly attributed to metabolic changes triggered through priming prior to sowing, such as nucleic acid synthesis, ATP synthesis, accumulation of phospholipids, and activation of antioxidant mechanisms (Kumar et al, 2022; dos Santos Guaraldo et al; 2023, Narejo et al, 2023; Xia et al, 2023; Khalequzzaman et al, 2023). This early metabolism shift provides a booster effect for plant growth and development under stress conditions.…”

Priming‐mediated stress tolerance in plants stimulates defense mechanisms and enables plants to cope with future stresses. Seed priming has been proven effective for tolerance against abiotic stresses; however, underlying genetic mechanisms are still unknown. We aimed to assess upland cotton genotypes and their transcriptional behaviors under salt priming and successive induced salt stress. We pre‐selected 16 genotypes based on previous studies and performed morpho‐physiological characterization, from which we selected three genotypes, representing different tolerance levels, for transcriptomic analysis. We subjected these genotypes to four different treatments: salt priming (P0), salt priming with salinity dose at 3‐true‐leaf stage (PD), salinity dose at 3‐true‐leaf stage without salt priming (0D), and control (CK). Although the three genotypes displayed distinct expression patterns, we identified common differentially expressed genes (DEGs) under PD enriched in pathways related to transferase activity, terpene synthase activity, lipid biosynthesis, and regulation of acquired resistance, indicating the beneficial role of salt priming in enhancing salt stress resistance. Moreover, the number of unique DEGs associated with G. hirsutum purpurascens was significantly higher compared to other genotypes. Coexpression network analysis identified 16 hub genes involved in cell wall biogenesis, glucan metabolic processes, and ribosomal RNA binding. Functional characterization of XTH6 (XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASE) using virus‐induced gene silencing revealed that suppressing its expression improves plant growth under salt stress. Overall, findings provide insights into the regulation of candidate genes in response to salt stress and the beneficial effects of salt priming on enhancing defense responses in upland cotton.
