Climate change and global warming represent the main threats for many agricultural crops. Tomato is one of most extensively grown consumed horticultural products can survive in a wide range climatic conditions. However, high temperatures negatively affect both vegetative growth reproductive processes, resulting losses yield fruit quality traits. Researchers have employed different parameters to evaluate heat stress tolerance, including evaluation leaf- (stomatal conductance, net photosynthetic rate, Fv/Fm), flower- (inflorescence number, flower stigma exertion), pollen-related traits (pollen germination viability, pollen tube growth) per plant. Moreover, several authors gone even further, trying understand plants molecular response mechanisms this stress. The present review focused on tomato during stage, since increase above optimum usually occurs late growing season. Reproductive-related directly affects final are regulated by genes such as transcriptional factors, shock proteins, related flower, flowering, set, epigenetic involving DNA methylation, histone modification, chromatin remodelling non-coding RNAs. We provided detailed list these their function under temperature conditions defining with aim summarize recent findings pose attention candidate that could prompt selection constitution new thermotolerant plant genotypes able face abiotic challenge.

With increasing plastic manufacture and consumption, microplastics/nanoplastics (MP/NP) pollution has become one of the world's pressing global environmental issues, which poses significant threats to ecosystems human health. In recent years, sharp researches have confirmed that MP/NP had direct or indirect effects on vegetative growth sexual process vascular plant. But potential mechanisms remain ambiguous. particles can be adsorbed and/or absorbed by plant roots leaves thus cause diverse This holistic review aims discuss plant, with special emphasis changes metabolic molecular levels. alter substance energy metabolism, as well shifts in gene expression patterns. Key aspects affected stress include carbon nitrogen amino acids biosynthesis hormone signal transduction, related genes, metabolism those involved pathogen defense. Additionally, provides updated insights into physiological responses plants exposed MP/NP, encompassing phenomena such seed/spore germination, photosynthesis, oxidative stress, cytotoxicity, genotoxicity. By examining impact from both perspectives, this sets stage for future investigations complex interactions between pollutants.

MicroRNAs (miRNAs) have been shown to be critical components in plant immunity. MicroRNA398 (miR398) is a highly conserved miRNA all land plants and plays crucial roles diverse biotic stress responses. However, the role of miR398 has not yet characterized tomato resistance against Botrytis cinerea. In this report, transcript levels sly-miR398b were strongly decreased B. cinerea-infected leaves overexpression resulted enhanced susceptibility. The attenuated expression cytosol Cu/Zn-SOD (CSD1), chloroplast (CSD2), guaiacol peroxidase (GPOD), as well activities superoxide dismutase (SOD) GPOD, collectively led increased hydrogen peroxide (H2O2) accumulation overexpressing plants. Furthermore, was induced by methyl jasmonate (MeJA) treatment. suppressed TomLoxD, LapA, PR-STH2 response cinerea MeJA Our data demonstrate that negatively regulates inducing reactive oxygen species (ROS) downregulating MeJA-responsive defense genes.

Tomato (Solanum lycopersicum) is significantly affected by drought. An excessive amount of reactive oxidative species (ROS) generated in tomato under drought stress, causing devastating effects on growth and yield. Drought stress response adaptation plants are complex their regulatory gene networks being investigated to improve our understanding. The signaling molecule, ABA (abscisic acid), one the key players response. Plants synthesize accumulate because can act membrane transporters, protein kinases, transcription factors, other hormonal pathways elicit appropriate In this review, we will discuss current knowledge how perform Moreover, offer future directions that extend understanding tomato's tolerance stress.

Aluminum (Al) toxicity is a serious environmental constraint facing crop production in acidic soils, primarily due to the oxidative damage it causes plant tissues. Alfalfa (Medicago sativa), globally important forage crop, highly susceptible Al-induced stress, necessitating development of Al-tolerant cultivars for sustainable production. In this study, we investigated regulatory role miR156 Al stress response alfalfa. Transcript analysis revealed significant downregulation alfalfa roots after 8 h exposure, suggesting negative Al. To further investigate regulating agronomic traits and alfalfa's tolerance, utilized short tandem target mimic (STTM) method silence (MsSTTM156), which led an upregulation SQUAMOSA PROMOTER BINDING-LIKE (SPL) genes, albeit with variable dose-dependent effects across different transgenic genotypes. Morphological characterization MsSTTM156 plants changes root architecture, shoot biomass, as well flowering time. Under overexpression (MsmiR156OE) resulted stunted growth reduced whereas moderate MsmiR156 silencing enhanced dry weight increased stem basal diameter. contrast, MsmiR156OE height, diameter, branching, overall biomass under conditions. At molecular level, modulated transcription cell wall-related genes linked such polygalacturonase 1(MsPG1) 4 (MsPG4). Furthermore, influenced expression indole-3-acetic acid (IAA) transport-related auxin transporter-like protein (MsAUX1) efflux carrier components 2 (MsPIN2), showing lower higher transcript levels, respectively, upon exposure. These findings reveal multi-layered mediating providing valuable insights into genetic strategies that regulate
