Thermopsis turcica is an endemic species of wild legume in Türkiye. The plant produces flower pistils with unusual morphological properties. The aim of this study was to determine the factors controlling the interesting feature of this plant. Particularly the controlling features of the flower meristem and the pistils that mutations in two genes and helps occurring the number of flower organs and can cause abnormalities, This study has attempted to explore the controlling feature of Thermopsis turcica, the young bud Arabidopsis CLV2, and CRC gene homologs were isolated and analyzed in different tissues. First, with total RNA isolated from the first thread degenerated primers synthesized cDNA expressions, second with a partial length cDNA cloning process made and the replicated set of analyses. The full-length cDNA of genes related to RACE analysis was carried out with the sequencing process. The real-time PCR method was applied for gene functional analyses with buds, sepals, petals and stamen and relative expression analysis of genes in the tissue of pistils. Full-length cDNA sequence for the gene CLV2 2557 bp, the encoded protein 716 amino acids, CRC 901 for full-length cDNA sequence of the gene—bp, the encoded protein 174 identified as amino acids. Alignment and phylogenetic analyses of CLV2 and CRC genes were found to be similar to other types of legumes in homologous sets. Real-time (RT-qPCR) PCR results relative to study courses with genes.

Communications in Theoretical Physics 2024年第10期76卷 14-25页

作者： arzu Akbulut Waseem Razzaq Filiz Tascan Department of Mathematics Faculty of Arts and Science Bursa Uluda? University Math Center House no 87 Rahmanyia Colony Department of Mathematics and Computer Sciences Faculty of Arts and Science Eskisehir Osmangazi University

In this study, the exact solutions for the propagation of pulses in optical fibers are *** values are given in the model used, and two nonlinear differential equations are *** equations are reduced to ordinary differential equations with the help of wave transformations. Then, the obtained differential equations are solved by two different methods,namely the modified simplest equation and the modified Kudryashov procedures. The solutions are given by hyperbolic, trigonometric and rational functions and the results are useful for optics,engineering and other related areas. Finally three-dimensional, contour and two-dimensional shapes are given for some solutions. These figures are important for understanding the motion of the wave. The given methods are applied to the equations for the first time. To the best of the authors' knowledge, these results are new and have not been obtained in the literature. The results are useful for applied mathematics, physics and other related areas.
