The Gnetum genus is an important medical, grain, and oil crop with ambiguous phylogenetic placement in seed plants. In the current study, full-length transcripts from G. luofuense L. leaves were utilized for codon usage pattern analysis. For this, a total of 30,666 full-length transcripts were used for analysis after data filtering. The GC content of all transcripts was 44.75%, with GC1 being the highest at 50.98%. Eighteen codons were identified as optimal codons, and 16 codons ending with A/U, indicating a higher frequency of A/T codon usage. Advanced analyses indicated that other factors, such as natural selection, play an important role in shaping the codon usage patterns in Gnetum. This study will be beneficial for understanding both the evolutionary mechanisms as well as the history of Gnetum genus.

基于转录组数据的罗汉果密码子使用模式分析

该买麻藤属植物是一种重要的医药，粮食和油料作物在种子植物系统发育暧昧安置。在当前的研究中，来自罗浮草叶的全长转录本被用于密码子使用模式分析。为此，总共30,666个全长转录本用于数据过滤后的分析。所有转录本的GC含量为44.75％，其中GC1最高，为50.98％。18个密码子被确定为最佳密码子，而16个以A / U结尾的密码子表明A / T密码子使用的频率更高。先进的分析表明，其他因素（例如自然选择）在塑造Gnetum中的密码子使用方式方面也起着重要作用。这项研究将有助于了解Gnetum 属的进化机制和历史。
