Additionally, 2 weedy types, <em>P. frutescens</em> var. <em>frutescens</em> (WPF) and <em>P. frutescens</em> var. <em>crispa</em> (WPC), are commonly found in the country. This study aims to develop a core collection using 7 qualitative and 10 quantitative traits from 1227 <em>Perilla</em> accessions representing these 3 types (PF, WPF, WPC). Significant variations were observed among these types, with WPC displaying the most diverse leaf, stem, and flower colors, while PF had the largest plant size and seed weight. WPC exhibited the longest inflorescences but had lower values for most other traits. Several core collections were created: QL_Core (qualitative traits), QN_Core (quantitative traits), and A_Core (all traits + passport data), each containing 184 accessions (∼15 %). P_Core (PowerCore software) was the largest, with 362 accessions (∼29.5 %). The D_Core, consisting of 235 accessions (∼19.2 %), exhibited the highest variance and coefficient of variation, indicating the greatest diversity. Comparative analysis revealed that D_Core showed greater variation across all quantitative traits than the entire collection. The principal component analysis confirmed its genetic diversity, with a higher cumulative variation (90 % by PC5) than the entire collection (74.6 %). Boxplot analysis demonstrated wider dispersion, while analysis of variance indicated no significant differences in 7 traits. However, plant height, node number, and branch number were slightly higher in the entire collection. Overall, D_Core effectively represents the variation of <em>Perilla</em> accessions, making it a valuable collection for future genetic and breeding research.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"235 ","pages":"Article 121783"},"PeriodicalIF":6.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896008","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}

Bamboo is a rapidly growing and widely distributed renewable biomass resource, and composite hydrogels with multiple functions can be constructed based on bamboo powder. This study developed a bio-based multifunctional superabsorbent hydrogel (BP-AD) that features both water retention and intelligent fertilizer control functions by grafting bamboo power (BP) with diacetone acrylamide (DAAM) and acrylic acid (AA) through an ultrasonic-assisted green aqueous solution polymerization technique. Characterization of FT-IR, XRD, and TGA confirmed that BP-AD is functionalized with carboxylic acid and amide groups and endows the material with excellent thermal stability. BP-AD exhibited an exceptional water absorbency capacity of 1401.5 g·g⁻¹ in ultrapure water, and its water absorption kinetics followed the pseudo-second-order kinetic model (R²= 0.9991), indicating that chemical adsorption predominates in the moisture capture process. The adsorption of urea by BP-AD conforms to the Freundlich model, suggesting that multiphase multilayer adsorption is the mechanism behind urea adsorption. Density Functional Theory (DFT) calculations indicate that the adsorption of urea by BP-AD can be attributed to hydrogen bonding and electrostatic interactions. The release of urea from BP-AD aligns with both the Korsmeyer-Peppas model and Zero-order kinetic model, and regulated by an ionic strength response mechanism. This research integrates biomass resource conversion with precision modern agriculture by innovatively developing dual-functional hydrogels, offering technical support for sustainable agriculture.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"235 ","pages":"Article 121776"},"PeriodicalIF":6.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896009","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}

Although canola meal (CM) has an excellent nutrition profile, its application is limited to animal feed industries. With protein content up to 39 % per dry biomass, CM contains a substantial amount of vitamins, minerals, sugars, and digestible fibres. The extraction of nutrients for the development of low-volume, high-value products—such as canola meal extract—offers promising applications across diverse fields. Bypassing processing steps involving protein isolation and removal of undesirable components for food application, its use in non-food applications, such as microbial media supplement, is one of such opportunities. Microorganisms require an adequate supply of nitrogen for optimal growth, which is currently met through synthetic nitrogen sources or conventional extracts derived from plants, animals, or microbes (e.g., yeast extract). However, these conventional nitrogen sources are costly and contribute significantly to the operational expenses of biotechnology industries. Canola meal, an abundant agro-industrial byproduct in Canada with minimal market value, presents an untapped opportunity. With an appropriate extraction technique, it may be possible to develop a novel, value-added product that not only enhances the utility of canola processing but also mitigates the cost burden on microbial production industries. The current study compares pH and temperature-based extraction methods and their combinatorial effect on solvent-extracted CM. Alkaline extractions were conducted at pH ranging from 6 to 12 and temperature from 25^°C to 160^°C. A response surface method was used to analyze the effect of pH and temperature on the yield of solid extract and protein content. Effects of further defatting of CM and its treatment with acidic ethanol (30 % 1 M HCl in ethanol) were evaluated. Biocatalysis was performed in solid-state fermentation with <em>Aspergillus oryzae</em> and submerged fermentation with inherent microbes present on canola meal. Central composite design shows that alkaline pH had a greater effect on protein extraction as compared to temperature. Although yields of solid extracts (397 ± 8 mg/ g of CM) and protein (51.8 % of extract) were significantly higher (P &lt; 0.05) during subcritical temperature (160^°C) at alkaline pH (11.5), amino acid profile and contents were better in bio-catalyzed extracts. The highest protein content in the solid extracts was obtained when <em>A. oryzae</em> pretreated CM was extracted at an alkaline pH. Additional defatting did not make significant changes in the yield, and compared to chemical pretreatment with organic solvents, the microbial method resulted in a higher yield.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"235 ","pages":"Article 121772"},"PeriodicalIF":6.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896012","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}

This study systematically investigates the structural evolution and kinetic behavior of sugar products during mandelic acid (MA) pretreatment. At low MA concentrations (2 %), the process primarily induces mild hydrolysis of the hemicellulose main chain, yielding high-value xylooligosaccharides (31.45 g/kg). As MA concentration increases, xylooligosaccharides are further hydrolyzed into xylose, alongside the formation of degradation products such as furfural. Post-pretreatment, the main structure of residual hemicellulose is β-D-xylose. Notably, key side-chain groups, including 4-O-methyl-α-D-glucuronic acid and O-acetyl groups, are preserved under mild acidic conditions but progressively cleaved with increasing pretreatment severity. This structural evolution lays the foundations for targeted depolymerization into xylose. Kinetic analysis reveals a biphasic hydrolysis pattern: a fast phase (k_f = 6.09 ×10⁵ min⁻¹, E_a = 62.39 kJ/mol) associated with the amorphous region, and a slower phase (k_s = 1.10 ×10¹³ min⁻¹, E_a = 123.54 kJ/mol) corresponding to crystalline resistance. The overall hydrolysis rate of hemicellulose exceeds the degradation rate of xylose (k₂ = 7.06 ×10⁶ min⁻¹, E_a = 76.66 kJ/mol), enabling selective xylose production. Optimal conditions, 150 °C and 5 % MA, maximize xylose yield while minimizing degradation. The activation energy landscape positions xylose degradation between the fast and slow hydrolysis phases of hemicellulose. Based on these findings, a multi-parameter synergistic model integrating temperature, acidity, and time was developed to guide the efficient and selective conversion of hemicellulose to xylose. This approach enhances the valorization of hemicellulose and supports ecological sustainability and the advancement of a green sugar-based bioeconomy.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"235 ","pages":"Article 121786"},"PeriodicalIF":6.2,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896010","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}

The developmental processes underlying flower formation and the critical stages of sex differentiation in this species remain poorly understood. This study investigated the cymose panicle structure and the spatial distribution of male and female flowers, and conducted detailed morphological and cytological analyses across 15 developmental stages. The observations revealed that both male and female flowers initially passed through a bisexual phase before one set of sexual organs was arrested and underwent abortion during a broad developmental window. Ovule abortion in male flowers primarily occurred during the pre-meiosis to the pre-mitosis stage (S10–S11), while in female flowers, pollen abnormalities appeared at the post-meiosis stage, specifically during the first mitotic division (mitosis Ⅰ, S11), preceding the arrest of the styles and filaments. Distinct features, including abnormal cell plate degradation and formation, pollen degradation, calcium oxalate crystal-associated anther dehiscence, extensive programmed cell death (PCD) and other abnormalities were observed in the sterile anther of female flowers. These results identified megaspore mother cell (MMC) pre-meiosis (S10c) as the point of sex determination, and MMC meiosis and pollen mitosis I (S11) as the onset of visible sex differentiation.
