“…Heat shock protein 70 (HSP), a protein typically induced in response to high temperatures, has a chaperone function as improperly folded proteins accumulate under stressful conditions [74] . The interactors discussed so far support the previous data demonstrating that ProSys can improve tolerance against abiotic and biotic stress and enhances both direct and indirect plant defences [19] , [22] , [75] .…”

“…A previous study has demonstrated that spraying rice plants with OsPep3 peptide increases plants’ resistance to pathogens . Similarly, irrigating tomato plants with systemin peptide improves their defense response . Based on these findings, we hypothesized that tomato plants sprayed or irrigated with SpPIP1 could enhance their tolerance.…”

“…hirsutum cDNA library. Overexpression of GhZFP1 has been demonstrated to enhance salt stress and Rhizoctonia solani. In barley, overexpression of the Hordeum vulgare root abundant factor ( HvRAF ) gene led to increased resistance against Ralstonia solanacearum strain GMI1000, along with improved plant resistance to high salinity in Arabidopsis. The tomato systemin, an 18 aa peptide isolated from damaged tomato leaves, has demonstrated the ability to activate plant immunity against insect pests and pathogens, while also enhancing tomato resistance to salt stress. − Therefore, it is plausible that peptides or other key factors involved in enhancing plant resistance may also have a role in modulating salt stress. However, it is highly likely that only a fraction of the SSPs are currently known, and the majority of crucial SSPs in tomato remain unannotated.…”

Tomato is a globally important horticultural and economic crop, but its productivity is severely affected by various stresses. Plant small secretory peptides have been identified as crucial mediators in plant resistance. Here, we conducted a comparative transcriptome analysis and identified the prePIP1 gene from Solanum pimpinellifolium (SpprePIP1), as an ortholog of Arabidopsis prePIP1 encoding the precursor protein of PAMP-induced SSP 1. The expression level of SpprePIP1 is transcriptionally induced in tomato upon infection with Phytophthora infestans (P. infestans), the pathogen responsible for late blight. Overexpression of SpprePIP1 resulted in enhanced tomato resistance to P. infestans. In addition, exogenous application of SpPIP1, whether through spraying or irrigation, improved tomato resistance by enhancing the transcript accumulations of pathogenesis-related proteins, as well as reactive oxygen species and the jasmonic acid (JA) levels. Integrated analysis of transcriptomics and metabolomics revealed the potential contributions of JA and phenylpropanoid biosynthesis to SpPIP1-induced tomato immunity. Additionally, SpPIP1 may strengthen tomato resistance to salt stress through the ABA signaling pathway. Overall, our findings demonstrate that SpPIP1 positively regulates tomato tolerance to P. infestans and salt stress, making it a potential plant elicitor for crop protection in an environmentally friendly way.

“…According to Taiz et al (2017), the culms of potassium-deficient plant-cane are thin and weak, with abnormally short internodes. High values of Na + in the soil inhibit the absorption of nutrients, mainly that of K + due to the ionic antagonism between these monovalent ions by competing for absorption and transport sites in the plasma membrane (Ali et al, 2021;Cirillo et al, 2022;Zhang et al, 2022).…”

Salinization reduces the osmotic potential of soil solutions and promotes the accumulation of toxic ions (Na+ and Cl-) in plants, causing nutritional imbalance and yield reductions. Thus, the objective of the present study was to evaluate foliar concentrations of nutrients and Na+ and stalk yields in sugarcane RB92579 under different electrical conductivities of irrigation water and leaching fractions (LF). The experiment was conducted in drainage lysimeters in a 5 × 2 factorial scheme with five electrical conductivities of irrigation water - ECw (0.5, 2.0, 4.0, 6.0, and 8.0 dS m-1) without (LF1 = 0) or with a leaching fraction (LF2 = 0.17), and four replicates. Increased ECw decreased the concentrations of N, P, K, Mg, S, Fe, Mn, Cu, and Zn and increased those of Ca, Cl, and Na, reducing the biomass production in two cycles (plant-cane and first ratoon). The use of a leaching fraction of 0.17 mitigated the deleterious effects of salinity on nutrient concentration and yield.
