Moringa, a miracle tree, is classified as an important herbal plant due to its immense medicinal and non-medicinal benefits. However, organic amendments in the soil can improve the growth and nutritious status of <i>M. oleifera</i> plants on a sustainable basis. The study evaluated the effects of organic and inorganic amendments on <i>M. oleifera</i> genotypes’ physico-chemical and nutritious values. Results revealed that organic and inorganic amendments showed a significant effect on plant growth, water relations, gas exchange, and nutritious attributes in <i>M. oleifera</i> genotypes, while the maximum effect was observed when these amendments were applied in combination with BCRF₅₀ (50% RF + <i>Bacillus</i> + Compost). The applications of organic and inorganic fertilizers improved the plant growth parameters as plant height was improved by 36% under different soil amendments as compared to CTRL and maximum plant height was observed when RF, <i>Bacillus</i>, and compost were applied in a combination at BCRF₅₀ (50% RF + <i>Bacillus</i> + Compost). Photosynthetic rate, stomatal conductance, water potential, and relative water content increased by 13, 29, 19, and 18%, respectively, under different organic and inorganic amendments compared to CTRL. Biochemical attributes chlorophyll a, chlorophyll b, total soluble proteins, superoxide dismutase, catalase, and peroxidase increased by 49, 50, 48, 48, 44, and 50%, respectively, under different organic and inorganic amendments as compared to CTRL and maximum improvement was observed when RF, <i>Bacillus</i>, and compost were applied in a combination at BCRF₅₀ (50% RF + <i>Bacillus</i> + Compost). Nutrient contents of nitrogen, phosphorous, and zinc increased by 80, 30, and 92%, respectively in <i>M. oleifera</i> leaves under different amendments. Among different genotypes, <i>M. oleifera</i> genotype GNK outclassed other genotypes due to its better genetic potential and better utilization of resources under different organic and inorganic amendments. The combination of RF, <i>Bacillus</i>, and compost at BCRF50 significantly enhances the nutritional value of <i>M. oleifera</i> by enhancing chlorophyll content, water relations, gas exchange parameters, osmolyte production, and antioxidant activities.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":"47 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11738-025-03771-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, significant knowledge is required about the genes in wheat plants that can restrict disease development. Contemporary studies indicate that flavonoid biosynthetic genes are involved in transcriptional and post-transcriptional gene regulation, growth, responses to environmental stimuli, and signal transduction.

The flavonoid biosynthetic pathway was discerned through KEGG mapping of the identified contigs and the key genes like <i>Chalcone synthase</i>, <i>Flavanone 3-dioxygenase</i>, and <i>Anthocyanidin synthase</i> were characterized. Expression analysis of these genes at varied time points post-pathogen infection on both resistant and susceptible wheat Near-Isogenic Lines revealed their association with development, metabolism, and defense response regulation.

Many enzymes involved in primary metabolism like respiration, photosynthesis, and biosynthesis of plant hormones, possess Zn as a cofactor for their moiety. Zn at elevated concentrations in soil has hazardous effects on plants and leads to retarded cell division and elongation, affects growth and biomass production, impairs photosynthesis, and is often linked with oxidative stress by inducing reactive oxygen species (ROS). <i>Andrographis paniculata</i> is one of the popular medicinal herbs in Asia. It serves a pivotal role in Ayurveda as a traditional medicine and a source of anti-cancerous drug andrographolide (AG). The current study focused on exploring the enhancement of AG content within the plant under zinc stress. The study highlights the impact of various concentrations of Zn (50, 100, and 150 mg kg⁻¹) as zinc sulphate (ZnSO₄ × 7H₂O) on plant health, antioxidative enzymes and elicitation of AG biosynthesis in <i>A. paniculata</i> in a pot experiment with sandy loam soil in the greenhouse. Growth attributes such as plant height and fresh and dry biomass of seedlings were reduced with consistent increases in concentrations of Zn. The activities of enzymes such as catalase, guaiacol peroxidase, peroxidase, ascorbate peroxidase, and glutathione reductase rose with increasing concentrations of Zn. The maximum applied concentration (150 mg Zn kg⁻¹) showed the maximum activity of all studied antioxidative enzymes. Elevated zinc concentrations in soil correlate with increased total phenolic content, MDA content, electrolytic leakage, and H₂O₂ levels in <i>A. paniculata</i>. As the Zn content in soil increased, the AG contents in <i>A. paniculata</i> leaves increased and was maximum recorded at 150 mg kg⁻¹ of Zn. The Zn levels in root and shoot demonstrated a marked linear correlation with the concentrations of Zn applied to the soil.

This AL priming effect was demonstrated by increases in plant leaf area and dry and fresh plant weights, which might have been related to increases in the CO₂ assimilation rate (P_n and P_max). Furthermore, the reduced photon absorption (ABS/RC) and heat dissipation (DI0/RC) rates as well as the observed increase in photosystem II (PSII) efficiency (the maximum quantum yield of PSII (F_v/F_m), photochemical quenching (<i>q</i>P), actual PSII efficiency (Ф_PSII)) and electron transport (the light-saturated electron transport rate (ETR) and electron flux beyond the first quinone electron acceptor of PSII (Q_A) evaluated as (1–V_J)) provide strong evidence of a higher tolerance to clomazone.

In this study, three maize hybrids (B73 × Mo17, B73 × Sids7, and B73 × NC358), sharing B73 as the female parent, were produced, field-grown, and maintained till maturity under limited and sufficient soil nitrogen. The impact of the developing reproductive sink on growth, yield, and dynamic changes in ear-leaf physiology was monitored at 0, 5, 10, 15, and 20 days after pollination. Under limited and adequate N conditions, B73 × NC358 outperformed B73 × Mo17 and B73 × Sids7 in yield and most tested traits. The enhanced yield in B73 × NC358 was associated with increased sink-strength traits and improved source capacity-related morpho- physiological characteristics. As grain filling progressed, B73 × NC358 consistently demonstrated higher biomass accumulation, leaf nitrogen, stover nitrogen, chlorophyll content, total soluble proteins, and elevated activities of nitrate reductase (NR) and glutamine synthetase (GS) compared to the other hybrids.

Carrot, a major vegetable crop, is particularly vulnerable to drought, which severely hampers its growth and yield. To address this challenge and ensure food security in the face of current and future climatic shifts, it is important to screen and adapt carrot varieties for improved drought tolerance. Therefore, current study was conducted to observe the response of two different orange carrot lines (B2566B and NB3999) under two drought stress levels (85% and 70%) under semi-controlled greenhouse conditions. Results showed that carrot line B2566B exhibited reduced leaf numbers and a 50% increase in lipid peroxidation under drought stress conditions. Contrarily, carrot line NB3999 showed minimal reductions in root length and diameter. Higher H₂O₂ content was observed in B2566B, while NB3999 had increased total phenolic content, total antioxidant activity, and antioxidant enzymatic activity, indicating its tolerance to drought stress. Physio-biochemical traits in NB3999 confirmed its resilience to drought stress at both 85% and 70% levels. The root meristematic tissue of both lines was used for transcriptomic analysis. RNA-Seq analysis identified 788 genes upregulated in NB3999 under drought conditions compared to B2566B. qRT-PCR validation confirmed significant upregulation of these genes under 70% and 85% drought stress, with two genes, PER (peroxidase N1-like) and CYT (cytochrome P450), showing downregulation.
