Summary: In this study, the changes in plasma membrane proteins during Magnaporthe oryzae infection in rice were analyzed, and differentially expressed proteins associated with vesicle trafficking were identified. Among them, a novel plant-specific protein OsNPSN13 was upregulated and overexpression of this gene enhanced blast resistance in transgenic rice plants. These findings provide new insights into the plant immunity-associated vesicle trafficking network in the interaction between rice and blast fungi.

Summary: Soil salinity is a critical issue for rice production and is often linked to phosphorus deficiency. Plant hormones such as brassinosteroids have been shown to play a role in plant response to stress. This study compared the growth and root characteristics of two rice cultivars under salt stress, phosphorus limitation, and brassinosteroid treatment. The results showed that salt mainly affected root size and extent, while phosphorus supply mitigated the negative effects of salt on root growth in one of the cultivars. Brassinosteroid treatment had minimal impact on plant development in both experiments. Root traits may be useful for selecting salt-tolerant and phosphorus-efficient rice cultivars.

Summary: By analyzing the cell wall proteins of tomato seedlings under salt stress, it was found that there were significant changes in the cell wall proteins of salt-tolerant and salt-sensitive tomato genotypes. Proteins associated with signal transduction and alterations to cell wall polysaccharides increased in response to salt stress in both genotypes. Additionally, there were different metabolic changes between the two genotypes in response to salt stress. The salt-tolerant genotype showed decreased Na+ accumulation and enhanced regulation of redox balance and cell wall lignification in response to salt stress.

Summary: Salt stress negatively affects root growth, root border cell (RBC) number, and mucilage layer thickness in rice. Time kinetics analysis reveals that a small portion of seedlings already respond to salt stress within one day. These findings are important for understanding the mechanism of salt stress resistance in rice and for constructing models.

Summary: Our study revealed that high concentrations of zinc can affect the growth of rice seedlings and root cell death, but also stimulate glutathione synthesis, reduce levels of reactive oxygen species (ROS) and malondialdehyde. A total of 42 zinc-responsive proteins were identified, with proteins involved in redox regulation, defense responses, sulfur metabolism, and proteolysis being induced while those of energy production and cell wall biogenesis were decreased.

Summary: This study discusses the role of salinity responsive metabolites in rice and its wild species. Salinity stress severely affects rice productivity, and while many important physiological and molecular responses have been studied, the role of salt stress and microbes-induced metabolites in overcoming salt stress in rice has been less explored. Metabolomic studies have allowed for a comprehensive analysis of rice salt stress responses. This review discusses the alterations in various metabolites triggered by salt stress in rice and their significant roles in salinity tolerance, including as signaling molecules and protective agents. The accumulation of metabolites induced by salinity stress varies between salt-sensitive and tolerant rice genotypes, contributing to their different degrees of salt tolerance. Additionally, certain tolerance metabolites may induce unique pathways for defense mechanisms in salt-tolerant rice varieties, suggesting their potential roles as universal biomarkers for salt tolerance. The review also explores the involvement of rhizosphere microbes in rice salt tolerance. Overall, this study provides valuable insights into salt-induced metabolites in different rice genotypes and their relationships with stress genes, offering a reference point for biomarker design in rice. It also helps to decipher metabolic systems associated with salt tolerance in rice, which can be useful for developing salt-tolerant rice cultivars through conventional breeding, genetic engineering, or exogenous application of metabolites.

Summary: Leaf morphology is an important trait for plant architecture and stress resistance. In this study, a rice mutant, ltr1, with rumpled leaves and decreased grain yield was identified. LTR1, a wax synthesis gene, was found to be constitutively expressed in various tissues, with higher expression in leaves and panicles. Overexpression of LTR1 increased grain yield and positively regulated salt stress by affecting water and ion homeostasis. These findings provide insights into the molecular mechanisms of leaf morphogenesis and stress response, and offer a potential strategy for stress-tolerance breeding.

Summary: Salinity is a major stress that affects crop growth, especially cereals. Zinc (Zn) is essential for cultivating rice, and different application methods of Zn, such as ZnS, can help alleviate the issue of poor micronutrient uptake in salt-affected soils. Inoculating arbuscular mycorrhizae (AMF) can further improve Zn uptake and alleviate salinity stress. This study showed that ZnS with AMF performed significantly better in enhancing rice production and increasing Zn concentration in grains.

Summary: In recent decades, the concern for environmental pollution caused by chromium (Cr) has increased. This review summarizes the biogeochemical processes that regulate the mobilization, accumulation, bioavailability, and toxicity of hexavalent chromium [Cr(VI)] in soils. The impacts of Cr(VI) on plant growth and development, as well as the oxidative stress it induces in plants, are highlighted. The review also discusses the mechanisms plants use to cope with Cr(VI) toxicity, such as avoiding absorption or detoxifying the compound through antioxidant production. Additionally, it explores recent advances in remediation techniques for Cr(VI)-contaminated soil and water, such as bioremediation/phytoremediation, organic amendments, and nano-remediation supplements.

Summary: Drought is a major constraint for agricultural productivity worldwide. Allelopathic hormesis, the low dose stimulatory effect of allelochemicals, can help alleviate the adverse effects of drought stress in plants. This study evaluated the potential of brassica water extract in enhancing drought tolerance in wheat. The results showed that seed priming with 1.5% brassica water extract increased morphological attributes, antioxidant enzyme activities, and chlorophyll contents, while reducing hydrogen peroxide contents in wheat under drought stress. This priming technique improved the growth and drought tolerance of wheat cultivars by enhancing their physiological attributes and antioxidant defense system.

Summary: Plants have adapted to defend themselves against environmental stresses, including heavy metal toxicity, through programming, reprogramming, and stress tolerance. Beneficial microbes play a crucial role in improving plant productivity and mitigating abiotic stress. However, the simultaneous effect of heavy metal stress on soybeans and the need to reduce metal contamination in soybean seeds through sustainable approaches have been rarely explored. This article describes the initiation of heavy metal tolerance mediated by plant inoculation with endophytes and plant growth-promoting rhizobacteria, the identification of plant transduction pathways, and the impact of microbial inoculation on stress metal tolerance.

Summary: The optimal nitrogen application rate, source, and timing are crucial for achieving high wheat yield. This study examined the effects of various nitrogen sources (common urea, Zn-coated urea, neem-coated urea, and polymer-coated urea) and application methods (basal and split application) on wheat growth, physiology, yield, and related traits. The results showed that neem-coated urea applied in splits was the most effective source, followed by Zn-coated, polymer-coated, and common urea. Split application also improved growth and overall yield compared to basal application.

Summary: The purpose of this study was to assess the vulnerability of different phosphate-based fertilizers to cadmium contamination in agricultural soil using Brassica campestris. The results indicated that the use of rock phosphate (RP) as a fertilizer resulted in more cadmium contamination compared to the other two fertilizers (DAP and NP). It is recommended to choose alternative fertilizers with lower cadmium concentrations to reduce the potential of contamination.
