Journal of soil science and plant nutrition, Год журнала: 2023, Номер 24(1), С. 54 - 73

Опубликована: Дек. 26, 2023

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Abstract Background and Aims Climate change is happening causing severe impact on the sustainability of agroecosystems. We argue that many abiotic stresses associated with climate will be most acutely perceived by plant at root-soil interface are likely to mitigated this globally important interface. In review we focus direct impacts change, temperature, drought pCO 2 , roots rhizospheres. Methods Results consider which belowground traits impacted discuss potential for monitoring quantifying these modelling breeding programs. specific combined stress role microbial communities populating interface, collectively referred as rhizosphere microbiota, in interactions under plastic responses a way adapting plants change. then go has understanding complex problem suggest best targets adaptation mitigation finish considering where main uncertainties lie, providing perspective research needed.

Plasticity of Root System Architecture and Whole Transcriptome Responses Underlying Nitrogen Deficiency Tolerance Conferred by a Wild Emmer Wheat QTL

Plant Cell & Environment, Год журнала: 2025, Номер unknown

Опубликована: Янв. 30, 2025

ABSTRACT Our aim was to elucidate mechanisms underlying nitrogen (N)‐deficiency tolerance in bread wheat (cultivar Ruta), conferred by a wild emmer QTL (WEW; IL99). We hypothesised that the IL99 is driven enhanced N‐uptake through modification of root system architecture (RSA) underscored transcriptome modifications. Severe N‐deficiency (0.1 N for 26 days) triggered significantly higher plasticity compared Ruta modifying 16 RSA traits; nine which were IL99‐specific. The change growth collectively characterised transition orientation from shallow steep, increased number and length, denser networks, enabling nutrient acquisition larger volume deeper soil layers. Gene ontology KEGG‐enrichment analyses highlighted IL99‐specific pathways candidate genes elevated under N‐deficiency. This included Jasmonic acid metabolism, key hormone mediating ( AOS1, TIFY, MTB2, MYC2 ), lignification‐mediated strengthening (CYP73A, 4CL ). ‘N‐metabolism’ identified as main shared pathway Ruta, with nitrate uptake predominant NRT2.4 while remobilisation strategy NRT2.3 These findings provide novel insights into response demonstrate potential WEW improving suboptimal conditions.

Sustainable agriculture and meeting the world's food needs face considerable obstacles from abiotic stresses such as soil salinity drought. This critical issue was addressed by our current study, which sought to uncover multi-trait bioinoculants hostile ecosystems that could help mitigate drought at same time.The Bacillus subtilis ER-08 (BST) strain isolated halotolerant plant Fagonia cretica collected Little Rann of Kachchh, India. Various biochemical molecular approaches were applied for detailed characterization BST isolate.The isolate demonstrated notable growth-promoting qualities. Fenugreek seed biopriming performed using isolate. The effect treatment on fenugreek developmental indices well alleviation examined under greenhouse conditions. produced 83.7 g ml-1 gibberellins (GA3) 176.1 indole-3 acetic acid. Moreover, hydrogen cyanide, siderophore, exopolysaccharides (EPS), ammonia, cellulase, protease, pectinase, chitinase also strain. Interestingly, 52% Fusarium oxysporum mycelial growth suppressed in vitro Furthermore, isolates functioned several stress conditions, instance, (4 6 ds m-1), pH (5, 7, 9), (PEG6000 10%, 20%, 30%), temperature (25°C, 35°C, 37°C, 55°C). study indicates might serve an effective bio-inoculant minimizing detrimental effects stresses.

Sugar beet is a crop with high sucrose content, known for sugar production and recently being considered as an emerging raw material bioethanol production. This also utilized cattle feed, mainly when animal green fodder scarce. Bioethanol hydrogen gas from this essential source of clean energy. Environmental stresses (abiotic/biotic) severely affect the productivity crop. Over past few decades, molecular mechanisms biotic abiotic stress responses in have been investigated using next-generation sequencing, gene editing/silencing, over-expression approaches. information can be efficiently through CRISPR/Cas 9 technology to mitigate effects cultivation. review highlights potential use management beet. Beet genes involved response alkaline, cold, heavy metal precisely modified via enhancing beet’s resilience minimal off-target effects. Similarly, help generate insect-resistant varieties by targeting susceptibility-related genes, whereas incorporating Cry1Ab Cry1C may provide defense against lepidopteron insects. Overall, enhance adaptability challenging environments, ensuring sustainable, high-yield

Modern omics toolbox for producing combined and multifactorial abiotic stress tolerant plants

Plant Stress, Год журнала: 2023, Номер 11, С. 100301 - 100301

Опубликована: Ноя. 21, 2023

Plants being sessile organisms, face environmental challenges and climate change scenarios, that often occur simultaneously (as dual or multifactorial) rather than as a single stress factor. Combined stresses may exert additive impacts on plant growth yields. The prime challenge to safely feed the burgeoning population, in light of issues, demands precise agriculture systems. Though traditional breeding methods have been utilised but with limited success owing time, cost, infrastructure constraints. Modern biotechnological tools, especially high-throughput omics including genomics, transcriptomics, miRNAomics, metabolomics, lipidomics beside others are advocated revolutionize science biology develop stress-smart crops. Omics databases, pipelines coupled machine learning, artificial intelligence, mathematical modelling proving highly effective not only deciphering mechanistic insights responses also enhancing stress-tolerance. This review presents current knowledge updates recent developments abiotic adaptive strategies against combined sequential stresses.

Abiotic stresses are among the major limiting factors for plant growth and crop productivity. Among these, salinity is one of risk development in arid to semi-arid regions. Cultivation salt tolerant genotypes imperative approaches meet food demand increasing population. The current experiment was carried out access performance different rice under stress Zinc (Zn) sources. Four were grown a pot exposed (7 dS m−1), Zn (15 mg kg−1 soil) applied from two sources, ZnSO4 Zn-EDTA. A control both kept comparison. Results showed that based on biomass accumulation K+/Na+ ratio, KSK-133 BAS-198 emerged as sensitive, respectively. Similarly, concentration, BAS-2000 reported Zn-in-efficient while IR-6 Zn-efficient genotype. Our results also revealed growth, relative water content (RWC), physiological attributes including chlorophyll contents, ionic concentrations straw grains all decreased stress. However, significantly higher shoot K+ saline conditions. application alleviates harmful effects by improving morpho-physiological enhancing antioxidant enzyme activities, uptake K Zn. beneficial effect more pronounced salt-tolerant in-efficient compared with salt-sensitive genotypes.
