However, the regulatory mechanisms of IPPIs across cellular compartments remain poorly understood. <em>Artemisia annua</em>, a medicinal plant renowned for its high yield of terpenoids, particularly the antimalarial drug artemisinin, serves as an excellent model for studying IPPIs function. In this study, we identified a novel dual-localized IPPI (AaIPPI2) in <em>A. annua</em> alongside the previously characterized plastid-localized AaIPPI1, and explored their contributions to terpenoid biosynthesis. Our results showed that AaIPPI2, primarily localized in cytoplasm, exhibited significantly lower catalytic activity toward IPP compared to AaIPPI1. Overexpression of <em>AaIPPIs</em> in their respective compartments enhanced the production of monoterpenes, particularly camphene and camphor. Interestingly, although artemisinin levels increased to 1.5 mg/g FW, the overall sesquiterpene synthesis did not significantly rise. This suggested that adequate levels of AaIPPI2 and its IPP substrates were manufactured in cytoplasm to compensate for its lower activity, thereby supporting sesquiterpene biosynthesis. This mechanism also facilitated the accumulation of cytoplasmic IPP and its flux into plastids for monoterpene biosynthesis. Conversely, monoterpene biosynthesis was limited by the availability of AaIPPI1 and IPP substrates. Additionally, interference with <em>AaIPPI1</em> expression impaired terpenoid synthesis in both compartments, indicating that IPP formation and its normal flow between cytoplasm and plastids were disrupted. These findings enhance our understanding of terpenoid synthesis regulation in <em>A. annua</em> and suggest strategies for optimizing terpenoid production in plants.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"229 ","pages":"Article 120989"},"PeriodicalIF":5.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807080","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}

Moreover, due to the impact of global climate change and human activities, the habitat of many medicinal plants has been degraded or migrated, and their yield and quality have been seriously affected. However, the distributional changes of <em>D. dasycarpus</em> remain poorly understood, and there is still a knowledge gap regarding the environmental factors influencing the quality of its medicinal material. This study, using Heilongjiang province (one of the core-suitable areas for <em>D. dasycarpus</em>) as a case study, based on species distribution models under current and future climate scenarios and fingerprint of Dictamni Cortex, constructing a targeted high-quality wild tending areas and hotspot counties. The results show that the potential suitable areas for <em>D. dasycarpus</em> exhibit a significant increasing trend under climate change scenarios. Still, the suitability within Heilongjiang province is gradually declining as the leading province of its distribution. The fingerprint results show that the overall quality of Dictamni Cortex samples varies across different areas in Heilongjiang province, with the highest-quality medicinal samples coming from Mudanjiang and Qitaihe cities. Statistical methods were used to explore the relationships between the five active components of the Dictamni Cortex and its overall quality. Additionally, spatial distribution layers of these components under different climatic scenarios and periods were constructed. Based on the above results, we recommended the targeted tending of Dictamni Cortex in specific counties and cities within Heilongjiang province.

Three irrigation levels were set based on 0.35 (W1), 0.50 (W2), and 0.65 (W3) of the local ETo (reference evapotranspiration). DVRT depths of 20 (F1), 40 (F2), and 60 cm (F3) were tested.

The feed quality and soil salinity reduction at the W3 irrigation level were lower than those at the W2 level, indicating that higher irrigation levels did not always yield greater benefits. Although the salt absorption capacity was not maximized at the DVRT depth of F3, biomass, feed quality, soil salt reduction, and water use efficiency were maximized at the same irrigation level. The optimal amount of irrigation water for each parameter depended on the DVRT depth, making it impossible to simultaneously achieve the maximum relative feeding value, salt absorption capacity, soil salt reduction, water use efficiency, crude protein, and net profit. The multi-objective optimization analysis demonstrated that when the ideal irrigation water volume was 3124.96–3181.88 m³ ha⁻¹ and the DVRT depth was 53.68–55.39 cm, the net profit, salt absorption capacity, soil salinity reduction, water use efficiency, crude protein, and relative feeding value of <em>Suaeda salsa</em> reached over 83 % of their maximum values.

This review systematically examines recent advances in elucidating the structural and chemical transformations of lignin during pulping and bleaching processes, with a focus on reaction mechanisms and their industrial implications. In acidic pulping, protonation and hydrolysis of ether bonds lead to lignin depolymerization, while competing condensation reactions form carbon-carbon linkages. Alkaline pulping primarily cleaves <em>β-O</em>-4 bonds using quinone methide intermediates, which fragment lignin and enable condensation. Different reagents exhibit distinct mechanisms during bleaching: Chlorine dioxide phenolic groups form quinones and cleave aromatic rings, hydrogen peroxide-generated hydroxyl radicals preferentially attack non-phenolic structures, and ozone directly disrupts electron-rich aromatic regions through cycloaddition. These chemical changes not only facilitate lignin removal but also affect pulp’s brightness, strength and environmental impacts. This review provides a fundamental framework of lignin chemistry during these processes for developing more efficient, sustainable pulping technologies.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"229 ","pages":"Article 121004"},"PeriodicalIF":5.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807085","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}

Testing results show that high-temperature olive oil lubrication can be divided into four stages: start-up lubrication stage, steady lubrication stage, transition lubrication stage, and lubrication failure stage (dry friction). The material wear mechanisms under olive oil lubrication at high temperatures mainly include abrasive wear, adhesive wear, fatigue wear, oxidation wear.
