“…Brassinosteroids (BRs) are polyhydroxy steroids, including brassinazole and 24-epibrassinolide (EBR), that are involved in numerous metabolic and physiological processes, including germination, cell division, cell elongation, and xylem differentiation (Della Rovere et al, 2022;Raza et al, 2023b). All plant organs and parts, including leaves, roots, flowers, and seeds, contain brassinosteroids (Manghwar et al, 2022).…”

“…| Salicylic acidAs a phenolic composite, salicylic acid (SA) modifies the expression of pathogenesis-related proteins. SA accelerates plant growth, development, photosynthesis, molecular mechanisms, and abiotic stress tolerance(Raza et al, 2023b;Kaya et al, 2020). Recent studies have shown that exogenously applied SA can improve HMs stress tolerance in different crops.…”

Due to anthropogenic activities, environmental pollution of heavy metals/metalloids (HMs) has increased and received growing attention in recent decades. Plants growing in HM‐contaminated soils have slower growth and development, resulting in lower agricultural yield. Exposure to HMs leads to the generation of free radicals (oxidative stress), which alters plant morpho‐physiological and biochemical pathways at the cellular and tissue levels. Plants have evolved complex defense mechanisms to avoid or tolerate the toxic effects of HMs, including HMs absorption and accumulation in cell organelles, immobilization by forming complexes with organic chelates, extraction via numerous transporters, ion channels, signaling cascades, and transcription elements, among others. Nonetheless, these internal defensive mechanisms are insufficient to overcome HMs toxicity. Therefore, unveiling HMs adaptation and tolerance mechanisms is necessary for sustainable agriculture. Recent breakthroughs in cutting‐edge approaches such as phytohormone and gasotransmitters application, nanotechnology, omics, and genetic engineering tools have identified molecular regulators linked to HMs tolerance, which may be applied to generate HMs‐tolerant future plants. This review summarizes numerous systems that plants have adapted to resist HMs toxicity, such as physiological, biochemical, and molecular responses. Diverse adaptation strategies have also been comprehensively presented to advance plant resilience to HMs toxicity that could enable sustainable agricultural production.

“…ABA plays a crucial role in mediating the response of rapeseed to salt stress, by regulating stomatal closure, antioxidant defense, and osmotic adjustment ( Zhu and Assmann, 2017 ). Salt stress and ABA also modulate the expression of stress-related genes, including those involved in ion transport, osmotic regulation, and stress signaling pathways in rapeseed ( Raza et al., 2023 ). Furthermore, salt stress and ABA have been shown to interact with other signaling molecules, such as calcium and reactive oxygen species (ROS), to modulate the physiological and molecular responses of rapeseed to stress ( Raza et al., 2023 ).…”

The Brassica napus (B. napus) LOR (Lurp-One-Related) gene family is a little-known gene family characterized by a conserved LOR domain in the proteins. Limited research in Arabidopsis showed that LOR family members played important roles in Hyaloperonospora parasitica (Hpa) defense. Nevertheless, there is a paucity of research investigating the role of the LOR gene family towards their responses to abiotic stresses and hormone treatments. This study encompassed a comprehensive survey of 56 LOR genes in B. napus, which is a prominent oilseed crop that holds substantial economic significance in China, Europe, and North America. Additionally, the study evaluated the expression profiles of these genes in response to salinity and ABA stress. Phylogenetic analysis showed that 56 BnLORs could be divided into 3 subgroups (8 clades) with uneven distribution on 19 chromosomes. 37 out of 56 BnLOR members have experienced segmental duplication and 5 of them have undergone tandem repeats events with strong evidence of purifying selection. Cis-regulatory elements (CREs) analysis indicated that BnLORs involved in process such as light response, hormone response, low temperature response, heat stress response, and dehydration response. The expression pattern of BnLOR family members revealed tissue specificity. RNA-Seq and qRT-PCR were used to validate BnLOR gene expression under temperature, salinity and ABA stress, revealing that most BnLORs showed inducibility. This study enhanced our comprehension of the B. napus LOR gene family and could provide valuable information for identifying and selecting genes for stress resistant breeding.

“…It is one of the fastest synthesized hormones in plant responses to abiotic stresses and plays an important role in modulating plant abiotic stress response, thereby causing osmotic adjustment, senescence, antioxidant defence and stomatal closure (Chen et al, 2020b). ABA regulates the expression of ABA-induced genes that are involved in osmoregulation, ion transport, and stress signalling pathways and can also interact with other signalling molecules, such as reactive oxygen species (ROS) (Raza et al, 2023), to transmit their signals through mitogen-activated protein kinase (MAPK) pathway (de Zelicourt et al, 2016). ILR3 can promote salicylic acid (SA)dependent defence response to Alfalfa mosaic virus and activate the ROS (Aparicio & Pallas 2017).…”

The basic helix–loop–helix (bHLH) IVc transcription factors (TFs) play central roles in controlling iron (Fe) homeostasis and biotic stress responses. However, their evolutions and functions in other abiotic stresses are poorly understood. In this study, the IAA‐LEUCINE RESISTANT3 (ILR3) homologs were traced roughly back to before the early origin of land plants and divided into six main clades (Clade A‐F). Further analysis found that the ILR3 orthologs were angiosperm‐specific, suffering from motif‐acquisition events and loose purifying selection. Synteny analysis displayed that the whole genome duplications (WGDs) contributed to the establishment of the IRON DEFICIENCY TOLERANT1 (IDT1, also called bHLH34)/bHLH104 lineage prior to the divergence of angiosperms. Sequence analysis revealed that the ILR3 homologs had some novel and conserved motifs except bHLH and leucine zipper (ZIP) domains. Particularly, Arabidopsis thaliana ILR3 (AtILR3) was a nuclear protein and greatly activated by ABA and CdCl2 stresses. Simultaneously, the molecular and genetic analyses suggested that the AtILR3 acted as a positive regulator in the ABA stress response through enhancing the ability of reactive oxygen species (ROS)‐scavenging, such as the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT). The inductively coupled plasma mass spectrometry (ICP‐MS) analyses exhibited that the AtILR3 affected the absorption of nutrient elements, especially iron elements, under ABA stress. Collectively, our findings could shed deep light on the origin and evolution of the plant ILR3s, as well as the functions of the AtILR3 under ABA stress.
