JAZ proteins, crucial in the jasmonic acid signaling pathway, play essential roles in plant growth, development, and responses to various biotic and abiotic stresses. This study identifies 22 <em>JAZ</em> genes in moso bamboo using bioinformatics. We conducted a comprehensive analysis of their physicochemical properties, gene structure, chromosomal localization, conserved structural domains and motifs, cis-acting regulatory elements, and evolutionary relationships. Furthermore, by mining transcriptome data, we delineated the expression patterns of the JAZ gene family during the rapid shoot development phase in moso bamboo. This analysis suggests a significant role for the <em>JAZ</em> genes in the growth and development of moso bamboo. Additionally, we predicted transcription factors that regulate <em>JAZ</em> and analyzed protein interactions to construct an initial <em>JAZ</em>-related regulatory network. This study provides a crucial foundation for understanding the functions of the JAZ gene family and elucidating the molecular mechanisms underpinning the rapid shoot development in moso bamboo.</p></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"7 ","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773139124000284/pdfft?md5=cfbe604a128690194163d53dfea76197&pid=1-s2.0-S2773139124000284-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140917771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the widespread adoption of bamboo as a building material presents some challenges, especially in relation to the durability of the material. In fact, being a natural material, it requires protection from atmospheric agents, such as rain and sun, as well as from attacks by insects and animals. Ensuring the longevity of bamboo involves implementing tailored treatments, precise precautions, and regular structural inspections to detect any potential degradation over time. In this context, the article focused on the monitoring of a structure made of bamboo and on the testing of an innovative system to identify the structural critical issues present, in the context of a FISR project which envisaged a cultural exchange between China and Italy. Starting from the survey of the structure carried out with a drone, a 3D model was then built using a commercial software. For the monitoring phase of the structure, an innovative system was used that exploits the YOLO v5s6 algorithm to identify structural critical issues, supported by a Virtual/Augmented/Mixed reality app developed by the authors. This app is useful not only during the monitoring phase, but also in the subsequent phase of disseminating information relating to the potential of the use of bamboo in the field of structural engineering. The tested and proposed methodologies have proven to be particularly useful and high-performance, especially regarding the monitoring of bamboo structures, in relation to the resolution of problems linked to their possible fragility and limitations in certain application areas. The contribution provided in this paper by Geomatics methodologies is evident to better highlight the potential of this eco-friendly material for its desirable ever-increasing use in the construction sector by becoming aware of its potential.</p></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"7 ","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773139124000247/pdfft?md5=e70f4ff1e047e2f0a569346b63651362&pid=1-s2.0-S2773139124000247-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140638863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Choline chloride and proline were utilized as hydrogen bond acceptors in a total of eight deep eutectic solvents, whereas glucose, sucrose, glycerol, ethylene glycol, acetylpropionic acid, malic acid, and lactic acid were used as hydrogen bond donors. This work examined the protein extraction from bamboo shoots using deep eutectic solvents. Single-factor experiments were conducted to determine the optimal composition of the deep eutectic solvents, along with the ideal gradients of material-liquid ratio gradients, water content, extraction time, and water bath temperature. The impact and interplay of various variables on the protein extraction rate of bamboo shoots were examined using the Box-Behnken Design and Response Surface Methodology. Both the water bath temperature and the extraction time significantly influenced the protein extraction rate of bamboo shoots. Notably, the interaction between extraction time and water bath temperature had the most substantial effect on the protein extraction rate of bamboo shoots. The quadratic response surface regression equation for the protein extraction rate of bamboo shoots relative to the actual values of each factor was obtained as follows: Protein extraction rate = −193.3275 + 3.8395 A - 18.7075 B + 6.3285 C + 0.2125 AB - 0.0089 AC + 0.024 BC - 0.02885 A² + 0.685 B² - 0.06455 C². Finally, this work predicted optimum extraction parameters for bamboo shoots with choline chloride-sucrose (molar ratio 1:2), a material-liquid ratio of 1:50, a water content of 74 %, an extraction time of 4 h, and a water bath temperature of 44 ℃. Under the optimal conditions, the protein extraction yield was 59.39±0.45 %, which aligned with the predicted value from the response surface fitting equation. This indicated that the optimised regression equation may have practical significance.
