植物自交不亲和性广泛存在于显花植物中,是防止近亲繁殖和促进开花植物遗传多样性和杂种优势的重要遗传机制。关于自交不亲和机制的研究多集中在S基因上。该文结合文献计量的方法,利用Hiscite、Citespace和VosViewer分析了基于S位点的植物自交不亲和机制研究的年代趋势、重点国家、重要机构、重要作者、研究前沿和研究热点,对蛋白质磷酸化、S-RNase泛素化和拟南芥属的演化作了简要论述,并根据目前的研究现状提出了该领域研究中存在的问题及解决对策,旨在为进一步研究提供重要参考依据。

Plant self-incompatibility is widely found in flowering plants. It’s an important genetic mechanism to prevent inbreeding and increase the genetic diversity and heterosis of flowering plant. About self-incompatibility mechanism, most of the researches focus on the S gene. In this paper, we use Hiscite, Citespace and VosViewer based on Bibliometrics to analyze self-incompatibility mechanism in the S-locus of plant, and have a brief discussion on protein phosphorylation, S-RNase ubiquitination and the evolution of Arabidopsis. According to the current research status in this field, we also put forward the existing problems and solutions to provide a reference for further study.
