Table_8_Chromosome Evolution in the Family Solanaceae.pdf

This review summarizes and discusses the knowledge of cytogenetics in Solanaceae, the tomato family, its current applications, and prospects for making progress in fundamental systematic botany and plant evolution. We compile information on basic chromosome features (number, size, morphology) and molecular cytogenetics (chromosome banding and rDNA patterns). These data were mapped onto the Solanaceae family tree to better visualize the changes in chromosome features and evaluate them in a phylogenetic context. We conclude that chromosomal features are important in understanding the evolution of the family, especially in delimiting clades, and therefore it is necessary to continue producing this type of data. The potential for future applications in plant biology is outlined. Finally, we provide insights into understanding the mechanisms underlying Solanaceae’s diversification that could substantially contribute to developing new approaches for future research.

本综述总结并探讨了茄科（Solanaceae，番茄所属的科）的细胞遗传学（cytogenetics）相关知识、当前应用情况，以及其在基础系统植物学与植物演化研究中取得突破的发展前景。我们整理了基础染色体特征（包括染色体数目、大小、形态）与分子细胞遗传学（molecular cytogenetics，含染色体显带及核糖体DNA（rDNA）图谱）相关的研究数据，并将这些数据映射至茄科系统发育树（phylogenetic tree）中，以便更直观地展现染色体特征的演化变化，并在系统发育框架下对其开展评估。本研究得出结论：染色体特征对于理解茄科的演化过程至关重要，尤其是在演化支（clade）的界定方面，因此持续生成此类研究数据具有必要性。本文还概述了该领域在未来植物生物学研究中的应用潜力。最后，本研究为阐明茄科物种分化的潜在机制提供了见解，这将为未来研究开发新的研究路径提供重要助力。
