However, additional research effort is still needed to elucidate the antibacterial mechanism involved. In this study, bioinspired CuO NPs were synthesized, and their antibiofilm strategies against <i>R. solanacearum</i> were systematically investigated. CuO NPs effectively inhibited the biofilm formation of <i>R. solanacearum</i> at various stages of maturity (24, 48, and 72 h) by damaging the cellular morphology and reducing the extracellular polysaccharide (EPS) and protein content of bacteria within biofilms. The motility activities of <i>R. solanacearum</i>, including swimming, swarming, and twitching, were significantly inhibited upon exposure to CuO NPs. Furthermore, we confirmed that both two-dimensional and three-dimensional structures of mature biofilms (at 24 h) were disrupted, as determined by confocal laser scanning microscopy (CLSM), atomic force microscopy (AFM), and scanning electron microscopy (SEM), revealing a scattered morphology and a disrupted surface topology pattern. Importantly, the quantitative reverse transcription polymerase chain reaction (qRT-PCR) was employed to assess the transcriptional levels of genes related to biofilm formation and virulence in <i>R. solanacearum</i> stems following treatment with CuO NPs. Notably downregulated genes included those involved in chemotaxis (<i>cheA</i> and <i>cheW</i>), EPS-related genes (<i>xpsR</i> and <i>epsE</i>), swimming activity (<i>flgC</i>, <i>fliA</i>), the quorum-sensing (QS) system (<i>solR</i>, <i>phcB</i>, <i>phcS</i>), the type III system (T3SS) (<i>prhI</i> and <i>hrpG</i>), and the two-component system (<i>pehS</i> and <i>pehR</i>).

The increases in soil moisture, improvement in leaf structure, and enhancement of the photosynthetic process under intercropping were the primary drivers of the accumulation of volatile compounds, particularly key quality indicators such as 2-acetyl-1-pyrroline and phytol, in pandan leaves.

The present review presents a comprehensive methodology of sex determination mechanisms in dioecious plants consisting of cytological, biochemical, morphological, and molecular traits which is an unquestionable requirement required for sexual distinction in dioecious plant species. A special emphasis is focused on molecular marker approaches like Inter-Simple Sequence Repeat (ISSR), Random Amplified Polymorphic DNA (RAPD), Amplified Fragment Length Polymorphism (AFLP), and Sequence Characterized Amplified Region (SCAR) molecular markers, which have potentially enhanced sex determination accuracy and efficiency. These markers have been utilized successfully in a range of dioecious crops such as <i>Pandanus</i> spp., <i>Carica papaya</i>, <i>Cannabis sativa</i>, and <i>Asparagus officinalis</i>. The review also points out the RAPD and ISSR conversion into SCAR for enhancing reproducibility and specificity, along with modern transcriptomic techniques for identifying floral sex-specific genes in economically important plants.

Rising rainfall due to climate change, evolving environmental regulations, and cost-driven harvesting practices have increased extraneous matter (EM) in sugar cane, reducing factory efficiency and sugar recovery. Despite its significant impact, EM cannot be regularly quantified in sugar factories due to the lack of practical measurement methods and is therefore still excluded from cane payment systems. We introduce near-infrared (NIR) spectroscopy as a rapid, nondestructive solution to this challenge. NIR calibration models for leaf content in shredded cane were developed using mixtures of clean cane, soil, and leaves with known EM concentrations, and soil content calibrations were built using incinerated ash as the reference method. Partial least-squares regression models with k-fold cross-validation were developed to correlate NIR spectra with reference values. Soil content based on ash analysis yielded strong calibration results (R<sup>2</sup> = 0.88), markedly outperforming sediment analysis (R<sup>2</sup> = 0.12). For the first time, NIR successfully predicted brown leaves (R<sup>2</sup> = 0.72), green leaves (R<sup>2</sup> = 0.73), and total leaves (R<sup>2</sup> = 0.88).

All studied traits exhibited significant variation (<i>p</i> ≤ 0.001), indicating substantial genetic variability among the genotypes.

Rapid determination of soil properties at different depths is essential for the precision management of farming inputs. Most existing studies focus on predicting surface soil properties using spectral data from a single sensor, while research exploring the potential of multisensor spectral fusion for soil analysis at varying depths remains limited. This study evaluated the predictive performance of: (1) single-spectrum modeling using visible and near-infrared (vis–NIR) and mid-infrared (MIR) spectrophotometers and (2) two spectral fusion methods─direct concatenation and outer product analysis of full-spectral absorbance─for five key soil properties: pH, total organic carbon (TOC), available phosphorus (AP), available potassium (AK), and magnesium (Mg), across three soil depths. The data set comprised 176 fresh soil samples collected from 59 locations across five arable cropping fields. Prediction models were developed using partial least-squares regression (PLSR) and support vector machine (SVM), whose performance was assessed using the coefficient of determination (<i>R</i><sup>2</sup>), root-mean-square error (RMSE), and ratio of performance to interquartile distance (RPIQ). Results showed that vis–NIR spectra generally outperformed MIR, with validation <i>R</i><sup>2</sup> ranging from 0.39 to 0.67 and RPIQ from 0.84 to 3.25, compared to MIR (<i>R</i><sup>2</sup> = 0.42–0.62, RPIQ = 0.97–3.08).

However, fusion was not always superior to single-spectrum models; for example, vis–NIR-SVM and MIR-SVM gave the best results for AK (<i>R</i><sup>2</sup> = 0.53, RPIQ = 1.45) and Mg (<i>R</i><sup>2</sup> = 0.61, RPIQ = 1.30), respectively.
