RING is a really interesting new gene which plays important regulatory roles in many developmental processes as well as in plant-environment interactions. In the present report, the Zm RHCP1 gene encoding a putative RING-HC protein was isolated from maize and characterized. The Zm RHCP1 protein contained 310 amino acid residues with a conserved RINGHC zinc-finger motif and two transmembrane（TM） domains. Zm RHCP1 was expressed ubiquitously in various organs（root, stem, leaf, seedling, immature ear, and tassel）, but its transcript levels were higher in vegetative organs than in reproductive organs. Moreover, the expression pattern of Zm RHCP1 in brace roots indicated that Zm RHCP1 functions in brace root initiation. In addition, Zm RHCP1 expression was regulated by abiotic stresses. The expression results suggested that Zm RHCP1 plays important roles in brace root development and abiotic stress responses. The findings of the present study provide important information to help us understand the function of Zm RHCP1 in maize.

The aim of this paper is to study the inheritance pattern of ear tip-barrenness trait in maize （Zea mays L.）. Ear tipbarrenness trait in maize can be classified into two types, tip-barren and tip-barrenless. Two inbred lines, lx01-3 （tipbarrenless type）, wx04-1 （tip-barren type）, and their F1, F2, BC1, BC2 generations were analyzed on their ear tip-barrenness types. Results showed that F1 was tip-barren type; the ratio of tip-barren type versus tip-barrenless type followed a 12.78： 1 ratio in F2 segregation population and a 2.75：1 ratio in BC1. Z2 test indicated that the trait of ear tip-barrenness type followed an inheritance pattern of 2 duplicate dominant genes. SPSS analysis indicated that the trait of ear tip-barrenness length is of abnormal distribution. Above results mean that：（1） The trait of maize ear tip-barrenness type is controlled by 2 duplicate dominant genes; tip-barren type is dominant over tip-barrenless type; （2） the trait of tip-barrenness length is a quantitative character controlled by polygene with major genes expected.

In this work,we focus on the conforming and nonconforming leap-frog virtual element methods for the generalized nonlinear Schrodinger equation,and establish their unconditional stability and optimal error *** constructing a time-discrete system,the error between the solutions of the continuous model and the numerical scheme is separated into the temporal error and the spatial error,which makes the spatial error τ-*** inverse inequalities in the existing conforming and new constructed nonconforming virtual element spaces are utilized to derive the L^(∞)-norm uniform boundedness of numerical solutions without any restrictions on time-space step ratio,and then unconditionally optimal error estimates of the numerical schemes are obtained *** needs to be emphasized is that if we use the pre-existing nonconforming virtual elements,there is no way to derive the L^(∞)-norm uniform boundedness of the functions in the nonconforming virtual element spaces so as to be hard to get the corresponding inverse ***,several numerical examples are reported to confirm our theoretical results.

Peeling strength can comprehensively reflect slider track safety and is crucial in car seat safety assessments. Current methods for determining slider peeling strength are primarily physical testing and numerical simulation. However, these methods encounter the potential challenges of high costs and overlong time consumption which have not been adequately addressed. Therefore, the efficient and low-cost surrogate model emerges as a promising solution. Nevertheless, currently used surrogate models suffer from inefficiencies and complexity in data sampling, lack of robustness in local model predictions, and isolation between data sampling and model prediction. To overcome these challenges, this paper aims to set up a systematic framework for slider track peeling strength prediction, including sensitivity analysis, dataset sampling, and model prediction. Specifically, the interpretable linear regression is performed to identify the sensitivity of various geometric variables to peeling strength. Based on the variable sensitivity, a distance metric is constructed to measure the disparity of different variable groups. Then, the sparsity-targeted sampling(STS) is proposed to formulate a representative dataset. Finally, the sequentially selected local weighted linear regression(SLWLR) is designed to achieve accurate track peeling strength prediction. Additionally, a quantitative cost assessment of the supplementary dataset is proposed by utilizing the minimum adjacent sample distance as a mediator. Experimental results validate the efficacy of sequential selection and the weighting mechanism in enhancing localization ***, the proposed SLWLR method surpasses similar approaches and other common surrogate methods in terms of prediction performance and data quantity requirements, achieving an average absolute error of 3.3 kN in the simulated test dataset.
