A high precision virtual restoration method for stone setting exemplified by Lingfeng Stone
No full textWith advancements in technology, virtual restoration of garden heritage has gained significant attention, yet the restoration of stone settings remains underexplored. Stone setting, small and naturally flexible, are vital elements in Chinese classical gardens. This paper introduces a comprehensive method for their virtual restoration, encompassing evidence verification, data acquisition, model creation, evaluation, and utilization of results. The approach aims to achieve high precision restoration of complex stone settings using 3D digital technology. Applied to the Lingfeng stone in Wenyuan Pavilion of Yuanmingyuan, the method involves 3D digitization for existing parts and photo perspective reversion, grid positioning, and informed speculation for missing sections. The accuracy of model is scientifically assessed, and the restoration results are effectively utilized. This case study confirms the efficacy of method in high precision virtual restoration, supporting the preservation and promotion of stone elements in classical gardens and enhancing the dissemination of garden heritage restoration achievements

No full textInterspecific genomic introgression is an important evolutionary process with respect to the generation of novel phenotypic diversity and adaptation. A key question is how gene flow perturbs gene expression networks and regulatory interactions. Here, an introgression population of two species of allopolyploid cotton (Gossypium) to delineate the regulatory perturbations of gene expression regarding fiber development accompanying fiber quality change is utilized. De novo assembly of the recipient parent (G. hirsutum Emian22) genome allowed the identification of genomic variation and introgression segments (ISs) in 323 introgression lines (ILs) from the donor parent (G. barbadense 3–79). It documented gene expression dynamics by sequencing 1,284 transcriptomes of developing fibers and characterized genetic regulatory perturbations mediated by genomic introgression using a multi-locus model. Introgression of individual homoeologous genes exhibiting extreme low or high expression bias can lead to a parallel expression bias in their non-introgressed duplicates, implying a shared yet divergent regulatory fate of duplicated genes following allopolyploidy. Additionally, the IL N182 with improved fiber quality is characterized, and the candidate gene GhFLAP1 related to fiber length is validated. This study outlines a framework for understanding introgression-mediated regulatory perturbations in polyploids, and provides insights for targeted breeding of superior upland cotton fiber.This article is published as Chen, Xinyuan, Xiubao Hu, Guo Li, Corrinne E.
