Across a biennial time frame spanning from 2022 to 2023, diverse siliceous substances were administered through foliar application to address seed-shattering issues and enhance growth parameters. The study was carried out utilizing a Randomized Complete Block Design (RCBD) involving seven treatments and 3 replications. The experimental site is situated in a semi-arid sub-tropical region known for hot summers and comparatively mild winters. Results revealed that the foliar application of potassium silicate at a concentration of 200 mg/L notably boosted plant height (42.86 cm), plant spread (19.68 cm<sup>2</sup>), root length (14.87 cm), and leaf dimensions (4.51 cm) compared to alternative treatments. Furthermore, the application of potassium silicate at 200 mg/L substantially decreased the number of shattered pods (262), while elevating the count of intact pods (91.23), overall pod tally (524.3), and seeds per plant (4718). Increased silicon levels were detected in capsules, suggesting a heightened silicon deposition in plant tissues after the utilization of siliceous substances. Principal component analysis and correlation assessments were utilized to evaluate the impacts of treatments and the interrelationships among variables.

Among various soil improvement techniques, soil stabilization remains one of the oldest and most widely adopted methods by engineers and geotechnical professionals. This paper introduces an innovative, environmentally sustainable approach that integrates soil and plant chemistry, leveraging the cation exchange capacity (CEC) of soil and the properties of biological plant extracts. CEC refers to the soil's ability to adsorb and exchange positively charged ions (cations). When the availability of free cations is limited, the soil's exchange capacity reduces, which can lead to a form of natural stabilization. CEC can be assessed through various techniques, with the methylene blue spot test being a preferred method due to its simplicity, cost-effectiveness, and rapid execution. Plant-based extracts, rich in anions, can interact with soil cations, effectively neutralizing their effects and contributing to stabilization and strength enhancement. This geobiological stabilization method has demonstrated promising results in terms of cost efficiency and applicability. It offers potential for use in highway embankment slope stabilization, subgrade improvement, forest conservation efforts, and broader ecological preservation initiatives.</div></div>","PeriodicalId":8774,"journal":{"name":"Biocatalysis and agricultural biotechnology","volume":"68 ","pages":"Article 103666"},"PeriodicalIF":3.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sense- and anti-sense fragments were inserted to vector, cloned in <em>E. coli</em> and cloning was confirmed through PCR and restriction digestion of plasmids isolated from positive colonies. Through sequencing, the direction of target gene fragments in the vector was confirmed. The recombinant plasmid was transformed into <em>Agrobacterium tumefaciens</em>, and through <em>in planta</em> transformation, six cisgenic lines were obtained. Synthesis of target siRNA was confirmed using stem-loop Reverse Transcription PCR. Comparative expression levels of <em>MIPS1</em> in RNAi lines were downregulated to 0.03–0.75-fold. The phytic acid level in mature pods was reduced significantly from 410.88 mg/100 g in wild type to 56.47–278.53 mg/100 g (32.22–86.25 % reduction). Germination, development and agronomic performance of the RNAi lines were comparable with those of wild type.</div></div>","PeriodicalId":8774,"journal":{"name":"Biocatalysis and agricultural biotechnology","volume":"67 ","pages":"Article 103693"},"PeriodicalIF":3.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
