Abstract

Introduction: Caleosins are recognized as the key proteins found in Lipid Droplets (LDs) and are crucial for the creation, maintenance, and breakdown of LDs. Nevertheless, our understanding of caleosins remains limited within Theaceae, a prominent botanical family encompassing economically significant tea and oil tea species.

Methods: In this research, we conducted a comprehensive genome-wide exploration and examination of the caleosin family in Theaceae species with sequenced genomes. The gene number of caleosin was similar among Theaceae species. Segmental duplication was the main form of caleosin expansion in Shuchazao (SCZ), Huangdan (HD), Biyun (BY), Tieguanyin (TGY), Longjing (LJ), C. lanceoleosa (Cla) and C. chekiangoleosa (CCH). Synteny analysis revealed one-to-more and more-to-one collinear relationships of caleosin genes among Theaceae species.

Results: Caleosins in Theaceae are categorized into either the H-family or the L-family, each exhibiting distinct motif structures and physicochemical properties. Expression analysis revealed an apparent flower-predominant expression pattern of caleosin genes in Theaceae species. In addition, most paralogous pairs displayed expression divergence.

Conclusion: This research enhanced our understanding of the lineage-specific evolution of caleosin genes in Theaceae, and is valuable for future functional analysis of this gene family in tea and oil-tea species.

对山茶科 Caleosin 家族的基因组分析揭示了特定世系的进化模式。

简介苍耳素被认为是脂滴（LDs）中的关键蛋白，对于 LDs 的形成、维持和分解至关重要。然而，我们对大叶茶科植物中的鲸蜡醇蛋白的了解仍然有限，而大叶茶科是一个重要的植物科，包括具有重要经济价值的茶叶和油茶品种：在这项研究中，我们对有基因组测序的茜草科植物中的鲸蜡色素家族进行了全面的全基因组探索和研究。结果表明，不同茶科植物中的卡来苷基因数量相近。在舒茶藻、黄丹藻、碧云藻、铁观音藻、龙井藻、C. lanceoleosa (Cla) 和 C. chekiangoleosa (CCH)中，片段式重复是主要的caleosin扩增形式。合成分析表明，在山茶科植物中，杜鹃花苷基因之间存在一对多和多对一的共线关系：结果：山茶科植物的岩白菜素可分为 H 家族和 L 家族，每个家族的岩白菜素都具有不同的结构和理化性质。表达分析表明，杜鹃花科植物中的杜鹃花素基因的表达模式明显以花为主。此外，大多数旁系配对基因显示出表达差异：结论：这项研究加深了我们对茶科植物中的卡来霉素基因特异性进化的理解，对今后在茶叶和油茶物种中对该基因家族进行功能分析具有重要价值。

期刊介绍： Current Protein & Peptide Science publishes full-length/mini review articles on specific aspects involving proteins, peptides, and interactions between the enzymes, the binding interactions of hormones and their receptors; the properties of transcription factors and other molecules that regulate gene expression; the reactions leading to the immune response; the process of signal transduction; the structure and function of proteins involved in the cytoskeleton and molecular motors; the properties of membrane channels and transporters; and the generation and storage of metabolic energy. In addition, reviews of experimental studies of protein folding and design are given special emphasis. Manuscripts submitted to Current Protein and Peptide Science should cover a field by discussing research from the leading laboratories in a field and should pose questions for future studies. Original papers, research articles and letter articles/short communications are not considered for publication in Current Protein & Peptide Science.
