Summary: The in vitro and in vivo efficacy of three biocontrol agents, Trichoderma viride, Pseudomonas fluorescence, and Bacillus subtilis, were tested against Rhizoctonia solani infection. All biocontrol agents significantly reduced the growth of R. solani, with T. viride showing the highest inhibition percentage. The biocontrol agents also enhanced coriander resistance to R. solani by stimulating salicylic acid, phenolics, and antioxidant enzymes.

Summary: This study explores the impact of long-term plant breeding on plant-associated microbiota and highlights the importance of microbiome in breeding processes. By analyzing the microbiome of Styrian oil pumpkins, it was found that there are significant differences in microbial composition and diversity between seeds and rhizosphere, with more substantial changes observed in seed microbiomes between genotypes. Additionally, potential plant-beneficial bacterial taxa were enriched in progeny seeds, indicating microbiome-driven breeding for plant-beneficial microbes.

Summary: Differential gene expression was found between genotypes, tissues, days post-inoculation, and inoculated/non-inoculated samples. After inoculation, CpPAL and CpChiIV were downregulated in MUCU-16, while CpLPOX and CpDEF were upregulated in M63. CpDEF showed higher overexpression after inoculation, indicating its potential as a marker for biotic stress.

Summary: The enhanced salt tolerance of squash ethylene-insensitive mutants suggests that ABA could mediate this tolerance during germination and early seedling development. The comparison of wild type and ethylene-insensitive etr2b mutant seeds germinated under water and exogenous ABA treatment showed that etr2b seeds germinated earlier than wild type and were also insensitive to ABA. The expression profiles of ethylene and ABA genes in dry and imbibed seeds demonstrated a clear crosstalk between ethylene and ABA in germination.

Summary: Different microplastics have specific and concentration-dependent toxic effects on the growth of Cucurbita pepo, with PVC identified as the most toxic and PE as the least toxic material. Microplastic pollution may result in yield and economic loss for C. pepo, as well as potential risks for entering the food chain.

Summary: Trichomes provide an excellent model for studying cell differentiation and proliferation. This study identified two major QTLs for trichome density in zucchini and further investigated the regulatory mechanism using functional annotations and transcription factor selection, laying a foundation for better understanding the density of multicellular nonglandular trichomes.

Summary: The study analyzed the genotype data of Cucurbita pepo, C. moschata, and C. maxima collected from USDA germplasm collections through genotyping-by-sequencing. The analysis revealed extensive genetic structure corresponding to geographical origin and morphotype/market class. Genome-wide associate studies identified signals for various traits, with the strongest signal found for the bush gene in C. pepo. This research provides valuable information for maintaining genetic diversity, developing breeding resources, and prioritizing whole-genome re-sequencing.

Summary: The study evaluated the antagonistic effect of selected yeasts against spoilage moulds. Several yeast isolates showed growth inhibition activity against different moulds, with Pichia kluyveri Y64 and Meyerozyma guilliermondii Y88 demonstrating high inhibition activity on apples. These yeasts have the potential to be further investigated as biofungicides.

Summary: The main goal of the paper is to extend interpolation using mapped bases to any basis and dimension without the need for resampling. The proposed method, called Fake Nodes Approach (FNA), provides an effective way of interpolating in the multivariate setting. The theoretical results are supported by numerical experiments demonstrating the robustness of the scheme.

Summary: This paper introduces the class of (beta, gamma)-Chebyshev functions and corresponding points, proving their orthogonality in certain subintervals. It investigates the cases where they become polynomials and shows their relationship with classical Chebyshev polynomials. Additionally, subsets of Chebyshev and Chebyshev-Lobatto points are instances of (beta, gamma)-Chebyshev points, and the behavior of Lebesgue constants at these points is studied by varying the parameters beta and gamma.

Summary: In this study, we extended the application of greedy algorithms and proposed solutions for the oscillation problem in approximating functions. We developed results on theoretically optimal interpolation points and introduced two algorithms for adaptively selecting spline interpolation points. One algorithm is tailored to a specific target function, while the other enables the definition of target-data-independent interpolation nodes.

Summary: This paper discusses the problem of choosing the scale or shape parameter of radial basis functions (RBFs) in kernel-based methods. It introduces a direct relation between the shape parameter and the curvature of RBFs at each point. Based on this relation, RBFs are characterized as scalable or unscalable, and their curvature is used to classify commonly used RBFs. The paper then proposes a curvature-based scaled RBFs method, where the shape parameters depend on the function values and approximate curvature values of the function to be approximated. Numerical experiments show that this method performs better than the standard fixed-scale basis and other shape parameter selection methods.

Summary: In this study, the use of mapped bases or fake nodes approach in numerical integration helped mitigate the Gibbs phenomenon and compute the quadrature weights of fake Chebyshev-Lobatto nodes analytically. Surprisingly, these weights coincided with the composite trapezoidal rule. Numerical experiments confirmed the effectiveness of the method in mitigating the Gibbs phenomenon without the need for resampling the given function.
