Abstract Aroma is a crucial quality trait in rice, primarily regulated by the Badh2 gene located on chromo-some 8. In this study, we identified novel allele of Badh2, badh2-I11, an aromatic rice variety, Hei126 (H126). This carries 55-bp deletion intron 11 gene, which leads to alternative splicing (AS), resulting both normal and aberrant transcripts. The transcript contains premature stop codon, leading reduced mRNA moderate accumulation compound 2-acetyl-1-pyrroline (2-AP). Genetic analysis F2 population derived from cross between H126 non-aromatic Huahang 48 (HH48) revealed segregation ratio consistent with Mendelian inheritance (1:2:1), phenotypic plants was 3:1. An InDel marker developed for efficient screening of badh2-I11 breeding population. This transitional phenotype highlights as unique germplasm, accumulating 2-AP while retaining partial function. study provides insights into molecular mechanism aroma production via intron-mediated offers valuable genetic resources tools breeding.

Soil salinization poses a serious threat to global food security, as high Na+ contents in soils hinder nitrogen use efficiency (NUE), affecting the growth and yield of crop plants. The present study aims explore effects different fertilizer types viz., NO3- (N1) NH4+ (N2) planting densities, D1: 30 × 10 cm, D2: 20 D3: on development, absorption utilization, formation. salt-tolerant rice variety 'Jingliangyou 3261' was exposed 0.3% salt irrigation water. Results revealed that N2 substantially improved by increasing number effective panicles rate grain-setting compared N1. In addition, also increased leaf chlorophyll content, dry matter accumulation, antioxidant enzyme activity such superoxide dismutase, peroxidase, catalase reduced content malondialdehyde. comparison with N1, treatment resulted an increase 12.21%, 31.89%, 37.53% total recovery (NRE), agronomic (NAE), respectively. This can be attributed enhanced metabolic activity, including nitrate reductase glutamine synthetase, more robust root system. Under N1 conditions, D3, D1 tillers but decreased percentage productive tillers, grains per panicle, grain-filling rate, thousand-grain weight, thereby reducing yield. Additionally, D3 significantly NRE NAE treatment. Therefore, rational selection type density (D3) is crucial for improving rice. would broaden scope agricultural solutions saline soils, potentially security regions where soil widespread issue.

The present study aimed to investigate the effects of different soil amendments coupled with nitrogen fertilizer on morpho-physiological characteristics and yield salt-tolerant rice under saline conditions. amendments, i.e., S1: zeolite amendment, S2: coconut coir S3: humic acid S0: no treatments, N1: urea, N2: slow-release N0: N fertilizer, were kept in main plots sub-plots, respectively, a split-plot design. variety 'Shuangliangyou 138' was exposed 0.3% salt irrigation water. results showed that during entire growth period, compared S0, S1 S3 treatments increased SPAD values by an average 6.3%and 5.5%, leaf area index 24.5% 19.8%, canopy interception rate 11.5% 4.1%, aboveground biomass 36.8% 13.9%, respectively. Moreover, conditions, tiller number per square meter, water potential, content, chlorophyll contents also improved urea than urea. promoted root vitality nutrient absorption as well enhanced activity antioxidant metabolism enzymes In sum, rational application could improve productivity saline-alkali land.

The global landscape is marked by climatic, socioeconomic, and demographic complexities, enhancing food production through byproducts has emerged as a powerful strategy to address these challenges. This review aimed analyze the potential impacts of VIUSID® agro, an amino acid–based growth promoter, on plant growth, productivity, tolerance salt stress. A quantitative systematic was conducted utilizing databases such Web Science, Scopus, Google Scholar. research papers highlighted positive effects agro production, well physiological biochemical indices related stress across various crops. Furthermore, this biostimulant can be administered in different doses application methods. also examined its during ex vitro acclimatization phase tissue culture. results demonstrated enhanced crop increased biomass accumulation, modulation photosynthesis, improved enzymatic antioxidant defenses, maintenance ionic homeostasis, all contributing superior performance. These findings suggest that beneficial for wide range crops, with effectiveness primarily attributed rich acid composition, which influences modulates processes within cells.

ABSTRACT Nitrogen (N) uptake and utilisation are crucial for improving rice yields, but the mechanisms of N absorption transportation under salt stress conditions still unclear. To address this gap, therefore, a field experiment was conducted from 2022 to 2023 evaluate characteristics metabolism, nitrogen use efficiency, yield in varying saline conditions. The comprised three irrigation treatments i.e., freshwater (S0) seawater mixtures 5 dS m −1 (S1), 11 (S2) simulate tolerant (ST), ‘Chaoyou 1000’ ‘Longliangyou 506’, sensitive (SS), ‘Ruanhuayou1179’ ‘Ruanhuayoujinsi’ varieties. Compared with S0, 2‐year average decreases total accumulation, grain production efficiency harvest index were 27.1%, 17.8% 10.5% S1 treatment 46.8%, 53.7% 41.2% S2 ST, respectively, all which lower than those SS. Additionally, gene expression N‐metabolising enzymes such as OsNR1 , OsGS1.1 OsGOGAOT transporter genes OsNRT2.1 OsNRT2.3 higher ST SS during heading stage stress, potentially enhancing transport utilisation. Moreover, significant positive correlation found between accumulation at maturity stress. Overall, findings not only provide theoretical support breeding improvement salt‐tolerant varieties also offer scientific guidance optimising management strategies
