“…However, under harsh conditions such as drought, cold, salinity, and heat stress, there is an excessive production of ROS that can lead to oxidative damage in plant cells, affecting membrane lipids, proteins, and nucleic acids (Islam et al 2022a; Zhang et al 2022). A very efficient antioxidant system that comprises enzyme scavengers to remove ROS in temperature‐stressed plants has evolved (Seleiman et al 2020; Islam et al 2022d). SOD is an enzyme that converts superoxide radicals into less harmful hydrogen peroxide (H 2 O 2 ).…”

Due to the increasing impact of worldwide environmental changes, temperature stress has become a major factor resulting in crop yield losses. The discovery of temperature‐stress‐responsive protein‐coding genes has made significant progress in understanding plants' complex stress response systems involving microRNAs (miRNAs). The miRNAs are triggered by heat or cold, thus confirming their significant functional role in cold or heat tolerance. Such dependable recommendations significantly broaden our understanding of the regulatory role of miRNAs in plant stress responses. This article presents novel perspectives on the substantial roles of plant miRNAs in responding to and acclimatizing to heat and cold stress. It comprehensively elaborates on miRNAs responsive to temperature stress, their regulatory mechanisms, and their targeted functions in plants. Additionally, the article investigates how miRNAs contribute to safeguarding plant reproductive tissues, mitigating damage caused by reactive oxygen species, modulating heat shock proteins, transcription factors, and phytohormones in the context of temperature stress. The conclusion outlines potential avenues for future research, highlighting the utilization of miRNAs and their regulatory functions to develop economically vital crops with enhanced tolerance to temperature stress, thereby ensuring future food security.

“…For example, methylation of GmMYB84 enhanced the soybean salt stress tolerance ( Zhang et al., 2020b ). Small non-coding RNAs such as miRNA have been identified as critical regulators of salt tolerance through modulation of target gene expression ( Islam et al., 2022 ; Zhang et al., 2022d ). For instance, small RNA-Seq analysis of soybean under salt stress treatment identified 17 differentially expressed miRNAs and 31 putative target genes.…”

The increasing sodium salts (NaCl, NaHCO3, NaSO4 etc.) in agricultural soil is a serious global concern for sustainable agricultural production and food security. Soybean is an important food crop, and their cultivation is severely challenged by high salt concentration in soils. Classical transgenic and innovative breeding technologies are immediately needed to engineer salt tolerant soybean plants. Additionally, unfolding the molecular switches and the key components of the soybean salt tolerance network are crucial for soybean salt tolerance improvement. Here we review our understandings of the core salt stress response mechanism in soybean. Recent findings described that salt stress sensing, signalling, ionic homeostasis (Na+/K+) and osmotic stress adjustment might be important in regulating the soybean salinity stress response. We also evaluated the importance of antiporters and transporters such as Arabidopsis K+ Transporter 1 (AKT1) potassium channel and the impact of epigenetic modification on soybean salt tolerance. We also review key phytohormones, and osmo-protectants and their role in salt tolerance in soybean. In addition, we discuss the progress of omics technologies for identifying salt stress responsive molecular switches and their targeted engineering for salt tolerance in soybean. This review summarizes recent progress in soybean salt stress functional genomics and way forward for molecular breeding for developing salt-tolerant soybean plant.

“…miRNAs can regulate the expressions of downstream genes at the post transcriptional level ( Mabuchi et al., 2018 ; Wang et al., 2020 ). Increasing amounts of evidences have shown that miRNAs are played important roles in plant responses to salt stress ( Yang et al., 2020 ; Islam et al., 2022 ). For example, the overexpression of Os-miR528 in creeping bent grass resulted in shortened internodes and increased tillers in transgenic plants.…”

Salt stress is an important factor which may negatively affect plant growth and development. High concentrations of Na+ ions can destroy the ion balance in plant somatic cells, as well as destroying cell membranes and forming a large number of reactive oxygen species (ROS) and other damage mechanisms. However, plants have evolved numerous defense mechanisms in response to the damages caused by salt stress conditions. Grape (Vitis vinifera L.), a type of economic crop, is widely planted throughout the world. It has been found that salt stress is an important factor affecting the quality and growth of grape crops. In this study, a high-throughput sequencing method was used to identify the differentially expressed miRNAs and mRNAs in grapes as responses to salt stress. A total of 7,856 differentially expressed genes under the salt stress conditions were successfully identified, of which 3,504 genes were observed to have up-regulated expressions and 4,352 genes had down-regulated expressions. In addition, this study also identified 3,027 miRNAs from the sequencing data using bowtie and mireap software. Among those, 174 were found to be highly conserved, and the remaining miRNAs were less conserved. In order to analyze the expression levels of those miRNAs under salt stress conditions, a TPM algorithm and DESeq software were utilized to screen the differentially expressed miRNAs among different treatments. Subsequently, a total of thirty-nine differentially expressed miRNAs were identified, of which fourteen were observed to be up-regulated miRNAs and twenty-five were down-regulated under the salt stress conditions. A regulatory network was built in order to examine the responses of grape plants to salt stress, with the goal of laying a solid foundation for revealing the molecular mechanism of grape in responses to salt stress.
