Unfortunately, no effective treatments are available to reduce the infection and, to date, the most promising strategy relies on controlling the meadow spittlebug <em>Philaenus spumarius</em> L. one of the main vectors of <em>X. fastidiosa</em>. Among insecticides and repellents, botanical insecticides represent valuable candidates. Their encapsulation into stable formulations, like nanoemulsions (NEs), can boosts the efficacy and stability. We investigated the toxicity, repellent, and antifeedant activity of carlina oxide, a polyacetylene isolated from the roots of <em>Carlina acaulis</em> L. (Asteraceae), and its NEs, against <em>P. spumarius</em> adults. In addition, we carried out electroantennographic (EAG) tests to evaluate the capability of the male and female antennae to perceive carlina oxide. EAG assays demonstrated that <em>P. spumarius</em> antennal olfactory system of both sexes is capable of perceiving carlina oxide over a wide range of doses and that females, at the lowest doses, have significantly greater olfactory sensitivity than males (0.01 and 0.1 µg, respectively (<em>p</em> &lt; 0.001)). In toxicity experiments, the percentage of adult survival in topical and fumigant trials was high, while it resulted significantly lower in ingestion trials. In olfactory tests, <em>P. spumarius</em> showed a slight preference for green beans treated with 1 % carlina oxide. However, no significant differences were observed between treatments when the concentration of carlina oxide was increased to 3 %. On the contrary, feeding tests showed a significant repellent effect of carlina oxide against <em>P. spumarius</em> adults up to 24 h after the treatment and a reduction in <em>P. spumarius</em> presence on treated green beans ranging from 51.2 % to 94.7 %, if compared with control green beans. Overall, this study sheds light on the possible development of effective and environmentally friendly formulations of carlina oxide to manage <em>P. spumarius</em>. Further studies are needed to evaluate the efficacy of this natural compound in field conditions, and to investigate its potential side effects on non-target species.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553039","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}

Transcription factors (TFs) play a crucial role in regulating lignin biosynthesis. However, investigations into the molecular mechanism involving NUCLEAR FACTOR Y subunit A (NF-YA) TFs in poplar lignin biosynthesis have yet been widely conducted. Here, <em>PtNF-YA11</em> was identified in <em>Populus trichocarpa</em>. It is predominantly expressed in the xylem and is responsible for regulating S-lignin biosynthesis in poplar. Further investigation revealed that overexpression of <em>PtNF-YA11</em> leads to an increase in S-lignin content, while the CRISPR-Cas9-edited <em>nf-ya11</em> poplars exhibit a decrease in S-lignin composition. Reverse transcription quantitative PCR data revealed that several genes associated with lignin biosynthesis, including <em>phenylalanine ammonia-lyase</em> (<em>PtPAL1</em>), <em>4-hydroxycinnamoyl CoA ligase</em> (<em>Pt4CL1</em>), <em>caffeoyl CoA O-methyltransferase</em> (<em>PtCCoAOMT</em>), and <em>ferulate 5-hydroxylase</em> (<em>PtF5H1</em> and <em>PtF5H2</em>), were upregulated in <em>PtNF-YA11</em>-overexpressing poplars but downregulated in <em>nf-ya11</em> poplars.

The inclusion of SL led to a 19.67 % increase in HLA yield and a 5.25-fold enhancement in FLA content compared to that without SL. The probable reason underlying SL's facilitation of HLA and FLA formation involved the effective dissolution of lignin and hemicelluloses to produce more precursors, as well as the incorporation of SL structure into the HLA molecule.

This regulation occurs through direct modulation of jasmonic acid (JA) biosynthesis and the JA-mediated signaling pathway.

This study aims to evaluate HemoQR, a novel point-of-care (POC) diagnostic method for haemoglobin (Hb) level detection using a smartphone-based system integrated with a paper strip without needing any reagent or additional auxiliary device. The goal is to assess the efficacy of this portable, user-friendly, rapid and accurate alternative for Hb measurement in large-scale intervention programmes such as Anaemia-mukt Bharat (AMB), which is crucial for diagnosing anaemia and monitoring various health conditions. The method involves the transfer of one drop of the blood sample to a paper strip that is made indigenously using plant based cellulosic sources for optimal functionality. The colour signal around the test spot is quantitatively analysed using a smartphone camera equipped with a custom application. The application processes the images through a machine learning algorithm to determine the Hb concentration. The system was evaluated in a clinical trial involving 200 participants, comparing its performance with the gold-standard laboratory Hb assay using automated haematology analyser. The smartphone-based method demonstrated high sensitivity (87.09 %) and specificity (96.11 %) for anaemia screening, as compared with laboratory results. The average detection time was significantly reduced to under q minute, and the system showed excellent user-friendliness and portability with no auxiliary device needed beyond the smartphone. Clinical trial results indicated that the device was accurate and reliable across different Hb levels. Summarily, HemoQR evidenced to be a promising tool for POC diagnostics. Its high accuracy, rapid results, and ease of use make it suitable for both clinical settings and remote areas with limited access to laboratory facilities. Future research will prioritize further validation and integration of the anaemia screening outcome with electronic health records from a large population cohort. This will help identify early indicators and signals of numerous emerging disease burdens that could escalate into secondary and tertiary health crises if not addressed in time.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142556046","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}
