Abstract

Glutamate receptor-like (GLRs) genes play essential roles in plant growth and development, and in coping with environmental stresses; however, information on GLR genes in Dendrobium species is lacking. We identified 25 GLR genes in three Dendrobium species, which were classified into three subfamilies based on their phylogenetic relationships. These genes have been relatively conserved during evolution. Analysis of cis-acting elements and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes annotations revealed the complexity and diversity of GLR gene regulation and functions. Further, gene expression analysis showed that different GLR members exhibited different expression patterns during Dendrobium growth and development, and some were involved in pathogen infection and in response to hormones. These results provide important information on the GLR gene family of Dendrobium, and a foundation for further functional, and trait regulation and improvement studies.

三种石斛谷氨酸受体样基因的全基因组鉴定和表达分析。

谷氨酸受体样基因（GLRs）在植物生长发育和应对环境胁迫中发挥着重要作用。然而，石斛属植物中GLR基因的相关信息尚缺乏。我们从3种石斛中鉴定出25个GLR基因，根据它们的系统发育关系将它们划分为3个亚科。这些基因在进化过程中相对保守。通过对顺式作用元件和基因本体以及京都基因与基因组百科全书注释的分析，揭示了GLR基因调控和功能的复杂性和多样性。此外，基因表达分析表明，不同GLR成员在石斛生长发育过程中表现出不同的表达模式，其中一些参与了病原体感染和激素应答。这些结果为石斛GLR基因家族的研究提供了重要信息，为进一步研究石斛的功能、性状调控和改良奠定了基础。
