The South-West Asian mountains, a significant global biodiversity hotspot, still have limited understanding of their biodiversity, especially the biodiversity in the commonly remote alpine and subnival zones. Aethionema umbellatum (Brassicaceae), whose distribution spans the Zagros and Yazd-Kerman mountain ranges of western and central Iran, illustrates this point remarkably well, encompassing a broad but geographically separated range. Phylogenetic analyses of morphological and molecular data (plastid trnL-trnF and nuclear ITS sequences) indicate a restricted distribution of *A. umbellatum* to the Dena Mountains in southwestern Iran's southern Zagros range, while populations from central Iran (Yazd-Kerman and central Zagros) and western Iran (central Zagros) represent distinct novel species, *A. alpinum* and *A. zagricum*, respectively. The newly discovered species, phylogenetically and morphologically similar to A. umbellatum, exhibit the characteristic features of unilocular fruits and one-seeded locules, highlighting their kinship. However, differentiating them is straightforward given the differences in leaf shape, petal size, and fruit characteristics. Despite significant efforts, the alpine plant life in the Irano-Anatolian region, as indicated by this study, continues to be poorly understood. The abundance of rare and locally endemic species in alpine habitats underscores their paramount importance for conservation.

Receptor-like cytoplasmic kinases (RLCKs) participate in numerous plant growth and developmental pathways, and they are also key regulators of plant immunity against pathogen attacks. Crop output is reduced and plant development is obstructed by environmental stimuli, such as pathogen infestation and drought. The precise contribution of RLCKs to sugarcane development is presently unclear.

Antiplasmodial compounds, abundant in plants, have formed the foundation for pharmaceutical drugs used in the prevention and treatment of malaria, a major health concern for many communities. Plants with antiplasmodial potential are not readily apparent, and the process of identifying them can be lengthy and costly. To identify suitable plants for investigation, one strategy leverages ethnobotanical insights, albeit with a focus on a relatively narrow range of species, despite its successes. A promising means of refining the identification of antiplasmodial plants and hastening the search for innovative plant-derived antiplasmodial compounds lies in the application of machine learning, incorporating ethnobotanical and plant trait data. This paper presents a novel dataset exploring antiplasmodial activity in three flowering plant families: Apocynaceae, Loganiaceae, and Rubiaceae (approximately 21,100 species). We further demonstrate the capacity of machine learning algorithms to predict the antiplasmodial activity of plant species. Predictive capabilities of various algorithms – Support Vector Machines, Logistic Regression, Gradient Boosted Trees, and Bayesian Neural Networks – are assessed and compared to two ethnobotanical selection approaches, based respectively on anti-malarial and general medicinal use. We assess the approaches using the supplied data, along with the reweighted samples, which have been adjusted to account for sampling biases. Evaluation in both contexts reveals that machine learning models consistently demonstrate higher precision than ethnobotanical approaches. Bias correction enabled the Support Vector classifier to achieve peak performance, demonstrated by a mean precision of 0.67, exceeding the mean precision of 0.46 achieved by the most successful ethnobotanical technique. We employ bias correction and support vector classification to assess the prospective antiplasmodial compound yield of plants. Approximately 7677 species from the Apocynaceae, Loganiaceae, and Rubiaceae families, as we estimate, require further exploration. Additionally, we doubt that at least 1300 active antiplasmodial species will be the subject of investigation using traditional methodologies. composite genetic effects The profound value of traditional and Indigenous knowledge for understanding the intricate relationship between people and plants is undeniable, yet these results underscore the substantial, largely unexplored potential within this knowledge for discovering new plant-derived antiplasmodial compounds.

South China's hilly regions are the primary area for cultivating the economically significant edible oil-producing woody plant, Camellia oleifera Abel. The deficiency of phosphorus (P) in acidic soils presents significant obstacles to the growth and productivity of C. oleifera. Plant responses to a variety of biotic and abiotic stresses, including tolerance to phosphorus deficiency, are demonstrably linked to the significant roles of WRKY transcription factors. The diploid genome of C. oleifera has been found to harbor 89 WRKY proteins, exhibiting conserved domains, which were subsequently grouped into three categories. The phylogenetic analysis of these proteins specifically led to the identification of five subgroups within group II. The conserved motifs and gene structure of CoWRKYs demonstrated the presence of mutated and variant WRKYs. Segmental duplication events were hypothesized to be the primary force behind the expanding WRKY gene family in C. oleifera. Transcriptomic analysis of two C. oleifera varieties, differing in phosphorus deficiency tolerance, revealed divergent expression patterns in 32 CoWRKY genes under phosphorus deficiency stress. The results of qRT-PCR analysis indicated that the expression levels of CoWRKY11, -14, -20, -29, and -56 genes were positively correlated with P-efficiency in the CL40 variety, contrasting with the P-inefficient CL3 variety. These CoWRKY genes exhibited continued parallel expression patterns under phosphorus deficiency, with a treatment duration of 120 days. The result revealed a connection between CoWRKY expression sensitivity in the P-efficient variety and the cultivar-specific tolerance of C. oleifera to phosphorus deficiency conditions. The contrasting expression of CoWRKYs in various tissues implies their possible role as a key factor in phosphorus (P) transport and reuse in leaves, modifying a broad range of metabolic pathways. KP-457 in vivo The study's data unambiguously demonstrates the evolution of CoWRKY genes in the C. oleifera genome, offering a valuable resource for future functional characterization studies of WRKY genes aimed at enhancing phosphorus deficiency tolerance in C. oleifera.

Crucially, remote measurement of leaf phosphorus concentration (LPC) is essential for agricultural fertilization strategies, crop development tracking, and advanced precision agriculture. To pinpoint the optimal predictive model for leaf photosynthetic capacity (LPC) in rice (Oryza sativa L.), this investigation leveraged machine learning algorithms, incorporating full-band spectral data (OR), spectral indices (SIs), and wavelet features. During the 2020-2021 period, greenhouse pot experiments were implemented, involving four phosphorus (P) treatments and two rice cultivars, to procure measurements of LPC and leaf spectra reflectance. Phosphorus insufficiency in the plants caused an increase in visible light reflectance (350-750 nm) and a reduction in near-infrared reflectance (750-1350 nm), according to the findings, in comparison to the control group receiving sufficient phosphorus. For linear prediction coefficient (LPC) estimation, the difference spectral index (DSI) composed of 1080 nm and 1070 nm wavelengths yielded the best results, as indicated by the calibration (R² = 0.54) and validation (R² = 0.55) coefficients. To ensure accurate prediction from spectral data, a continuous wavelet transform (CWT) was applied to the original spectrum, consequently enhancing denoising and improving filtering. The most effective model, employing the Mexican Hat (Mexh) wavelet function at a wavelength of 1680 nm and scale 6, demonstrated a calibration R2 of 0.58, a validation R2 of 0.56, and a root mean squared error (RMSE) of 0.61 mg/g. Random forest (RF) emerged as the top-performing machine learning algorithm in terms of model accuracy across the OR, SIs, CWT, and SIs + CWT datasets, outclassing the remaining four algorithms. The coupling of SIs, CWT, and the RF algorithm led to the superior model validation performance, evidenced by an R2 of 0.73 and an RMSE of 0.50 mg g-1. CWT presented the next best result (R2 = 0.71, RMSE = 0.51 mg g-1), followed by OR (R2 = 0.66, RMSE = 0.60 mg g-1) and lastly SIs (R2 = 0.57, RMSE = 0.64 mg g-1). Employing the random forest (RF) algorithm, which integrated statistical inference systems (SIs) with the continuous wavelet transform (CWT), yielded a 32% increase in the R-squared value for LPC prediction, significantly outperforming linear regression-based systems.
