This study aimed to investigate the role of isopentenyl transferase (<em>IPT</em>) and cytokinins in the regulation of vegetative branching in cotton (<em>Gossypium hirsutum</em> L.), hypothesizing that they play key roles in this process. Plant topping was implemented at peak flowering stage in field-grown cotton, and seedcotton yield, yield components, vegetative branching, fruiting, and cytokinin levels were examined over two consecutive years. The results showed that plant topping significantly enhanced the growth and development of vegetative branches, as evidenced by increased biomass, leaf area, and fruiting of vegetative branches, along with an accumulation of cytokinin accumulation at the tips of vegetative branches. This led to a 10.3 % rise in boll density and an 11.4 % increase in seedcotton yield compared with the non-topped control. The analysis of RNA-seq and qRT-PCR data revealed significant differences in the expression patterns of <em>IPT</em> genes, suggesting their importance in regulating the growth and development of vegetative branches. Furthermore, examing the <em>IPT</em> gene families in diploid and tetraploid cotton species identified a total of 8, 8, 16, and 16 <em>IPT</em> genes, categorized into 6 groups. Prediction of cis-acting elements of <em>GhIPT</em> gene family promoters and analysis of their expression profiles demonstrated the involvement of <em>GhIPT</em> genes in multiple plant growth pathways with specific spatio-temporal expression. The findings underline that plant topping enhances cytokinins accumulation at vegetative branch tips by up-regulating <em>IPT</em> genes, leading to increased vegetative branching, fruiting, and ultimately, seedcotton yield. This study provides valuable insights into enhancing cotton yield formation through the regulation of growth and development of vegetative branches by <em>GhIPTs</em> and offers a crucial reference for further investigations into the functions of <em>IPT</em> genes.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the direct sunlight, the nanostructured fabric cools the skin by 1.21 °C below ambient temperature, preventing an excessive increase of 8.2 °C in skin temperature.

The widespread production of mushrooms corresponds to disposal challenge, generating a significant volume of biowaste known as spent mushroom substrate. Their use as a catalyst can assist in lowering the expense of producing catalyst and the issue related to their disposal. Hence, the current study focused on developing a nanocatalyst for biodiesel synthesis from a blend of eight different types of oil. The catalyst was synthesized by using spent mushroom substrate (sawdust) of <em>Ganoderma lucidum</em> as the foundation of the catalyst, which was impregnated by BaO and K₂CO₃ via the wet-impregnation method followed by calcination. The developed nanocatalyst CSA/BaO@K₂CO₃ (CSA, calcined spent substrate ash) was characterized via various sophisticated methods like XRD (X-ray Diffraction), BET (Brunauer-Emmett-Teller), FT-IR (Fourier Transform Infrared Spectroscopy), FESEM (Field Emission Scanning Electron Microscopy) - EDX (Energy Dispersive Spectroscopy), XPS (X-ray photoelectron spectroscopy), HRTEM (High Resolution Transmission Electron Microscopy), and SAED (Selected Area Electron Diffraction). The HRTEM data showed that the average particle size of CSA/BaO@K₂CO₃ was 14.368 ± 0.262 nm, which confirmed it as a nanocatalyst. The synthesized catalyst’s catalytic activity was investigated for the transesterification of the blended oil (BO), where the influence of different optimum parameters was investigated. The catalyst consisted of a BET surface area of 16.441 m² g⁻¹ and resulted in the highest biodiesel yield of 94.36 ± 0.29 % under the optimized reaction conditions of 10 wt% of catalyst load, 9:1 of methanol to oil molar ratio (MTOMR), 65 ℃ of reaction temperature, and 34.67 ± 0.58 min of reaction duration. The biodiesel conversion under the optimized condition was also determined and found to be 95.85 %. The conversion of biodiesel was confirmed using spectroscopic techniques. The reusability test was carried out and found that the catalyst was reusable for up to three cycles. The energy of activation for transesterification using the synthesized catalyst was evaluated to be 83.55 kJ/mol.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142450298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering this, in the present study, thirty-five germplasm (seeds) of <em>E. foetidum</em>, which were collected from different regions of Northeast India, were planted in Randomized Block Design (RBD) in the experimental farm of CSIR-NEIST, Jorhat. All the agronomical and essential oil data were recorded as per standard protocol for two consecutive years (2018, 2019, and 2020). In the selection trial, one high essential oil-rich line was selected and planted at four different locations in NE India during the <em>rabi</em> season. By considering four environments of the genotypes, stability was checked using AMMI and the Eberhart-Russell model for four check varieties along with the identified strain, which was named Jor Lab LC-1. The identified variety was found to be more stable considering both the genotype and the environment interaction than the other genotypes. GC-FID and GC/MS analysis of Jor Lab LC-1 essential oil showed that trans-2-dodecenal (62.34 %) is the main component. Moreover, to the best of our knowledge, this is the first report on stability studies on <em>E. foetidum</em>.
