Salt stress is considered to be one of the major abiotic stresses influencing rice growth and productivity. To improve crop productivity in saline soils, it essential choose a suitable variety for mitigating salt gain deep understanding underlying mechanisms. The current study explored tolerance mechanism wild 'HD96-1 (salt resistive)' conventional 'IR29 sensitive)' by evaluating morph-physiological, transcriptomic, metabolomic approaches. Physiological data indicated that HD96-1 had higher chlorophyll content, photosynthetic efficiency, more stable Na+/K+, less H₂O₂, lower electrolyte leakage under compared with IR29. Transcriptomic showed expression NHXs IR29 was significantly down-regulated stress, leading large accumulation Na⁺ cytoplasm, CHLH, PORA, PORB down-regulated, inhibiting synthesis. maintained balance K⁺ increasing NHX4, there no significant change genes related synthesis, which made resistant than In addition, inhibited excessive synthesis hydrogen peroxide (H₂O₂) alleviated oxidative damage down-regulating ACX4 stress. promoted isoleucine up-regulating branched-chain amino acid aminotransferase 2 4 might promote raffinose stachyose gene galactitol synthase 2, which, turn, osmotic pressure relieved We also found inhibition photosynthesis light-harvesting chromophore protein complex (LHCH II)-related reducing glucose metabolites, respectively. enhances regulating C2H2 bHLH153 transcription factors.

Reduced glutathione (γ-glutamyl-cysteinyl-glycine, GSH), the primary non-protein sulfhydryl group in organisms, plays a pivotal role plant salt stress response. This study aimed to explore impact of GSH on photosynthetic apparatus, and carbon assimilation tomato plants under stress, then investigate nitric oxide (NO) this process. The investigation involved foliar application 5 mM GSH, 0.1% (w/v) hemoglobin (Hb, scavenger), GSH+Hb endogenous NO levels, rapid chlorophyll fluorescence, enzyme activities, gene expression related Calvin cycle seedlings (Solanum lycopersicum L. cv. 'Zhongshu No. 4') subjected short-term (100 NaCl) for 24, 48 72 hours. treatment notably boosted nitrate reductase (NR) synthase (NOS) elevating signaling salt-stressed seedling leaves. It also mitigated fluorescence (OJIP) curve distortion damage oxygen-evolving complex (OEC) induced by stress. Furthermore, improved photosystem II (PSII) electron transfer efficiency, reduced QA - accumulation, countered effects I (PSI) redox properties, enhancing light energy absorption index (PIabs). Additionally, enhanced key activities upregulated their genes. Exogenous optimized PSII utilization via NO, safeguarded reaction center, photochemical assimilation, ultimately net efficiency (Pn) Conversely, Hb hindered Pn reduction weakened positive plants. Thus, regulation photosynthesis requires involvement NO.

Recent Advancement on Physiological and Molecular Response to Cotton under Salt Stress: A Review

Опубликована: Июль 21, 2023

The production of plants and crops is influenced by environmental stress, which a serious scientific issue. Cotton an essential crop for producing natural fibers that are used to make biofuel edible oils. Salinity the main element influences cotton growth during beginning germination. type salt stage affects how sensitive plant stress. Developing ways enhance performance in salty circumstances can be aided understanding response salt, its mechanism resistance, management methods. Osmotic ionic imbalances originate due deposition soluble salts under salinity stress plant's root zone. Soil significantly reduces several factors, such as nutritional ion imbalance, K+, PO4-, NO- absorption, excessive chloride concentrations, osmotic hinders water availability. Research has revealed compared subsequent stages, germination, emergence, seedling phases more vulnerable ultimately seed yield delaying blooming, reducing fruiting positions, shedding fewer fruits, boll weight. morphology, roots, shoots, yield, fiber quality all strongly impacted It slows down feeding, cellular metabolism, photosynthesis. soil, water, climate affect responds During exclusion sodium or compartmentalization key adaptation process cotton. A major adaptive potential create types withstand provided up-regulation both physicochemical non-enzymatic antioxidant genes. successful strategy increase germination saline soils priming. Moreover, transgenic might viable choice improving environments. Our review focuses on impacts productivity well react also clarifies recent genetic advancements molecular breeding cotton's resistance soil salt.

AbstractSalt toxicity is one of the foremost environmental stresses that declines nutrient uptake, photosynthetic activity and growth plants resulting in a decrease crop yield quality. Seed priming has become an emergent strategy to alleviate abiotic stress improve plant growth. During current study, turnip seed with sodium selenite (Na2SeO3) was investigated for its ability mitigate salt stress. Turnip (Brassica rapa L. var.

Changes in the atmospheric CO2 concentration influence plant growth and development by affecting morphological structure photosynthetic performance. Despite evidence for macro-effects of elevated concentrations on morphology yield tomato, gene regulatory network key genes related to cross-regulation have not been reported. To identify hub metabolic pathways involved response tomato enrichment, weighted co-expression analysis was conducted using expression profiles obtained RNA sequencing. The role photosynthesis-related Soly720 (Solyc01g007720) CO2-enriched plants explored. Tomato responded enrichment primarily through RNA-related metabolism amino acids, fatty carbohydrates. networks were associated with development, including cellular components photosynthesis. Compared wild-type plants, transgenic overexpressing exhibited 13.4%, 5.5%, 8.9%, 4.1% increases height, stem diameter, leaf length, width, respectively, under high-CO2 conditions. improvements accompanied enhancement performance terms chlorophyll contents, characteristics, enzyme activities.

ABSTRACT Water sources in the Brazilian semi-arid region commonly contain high levels of dissolved salts their composition, standing out as one abiotic stresses that limit expansion irrigated fruit growing, especially salt stress-sensitive crops such sour passion fruit. Thus, use elicitors, proline, can be an effective alternative to mitigate stress plants. In this context, objective study was evaluate effects foliar application proline on chlorophyll fluorescence, growth, quality and tolerance with saline water during seedling formation phase. The experiment conducted from July October 2022, under greenhouse conditions Campina Grande, PB, Brazil, using a completely randomized design, 5 × 4 factorial scheme, five electrical conductivity irrigation - ECw (0.6, 1.2, 1.8, 2.4 3.0 dS m-1) four concentrations (0, 5, 10 15 mM), replicates two plants per plot. salinity 0.6 m-1 reduces maximum variable quantum yield photosystem II growth ‘BRS GA1’ seedlings. Foliar at ranging 6 8.05 mM increases plant height, stem diameter leaf area genotype is sensitive salinity, threshold level reduction unit increase 10.49%.
