Abstract

Plant malectin/malectin-like receptor-like kinases (MRLKs) play crucial roles throughout the life course of plants. Here, we identified 23 SiMRLK genes from foxtail millet. All the SiMRLK genes were named according to the chromosomal distribution of the in the foxtail millet genome and grouped into five subfamilies based on phylogenetic relationships and structural features. Synteny analysis indicated that gene duplication events may take part in the evolution of SiMRLK genes in foxtail millet. The expression profiles of 23 SiMRLK genes under abiotic stresses and hormonal applications were evaluated through qRT-PCR. The expression of , , and were significantly affected by drought, salt and cold stresses. Exogenous ABA, SA, GA and MeJA also obviously changed the transcription levels of , , and . These results signified that the transcriptional patterns of showed diversity and complexity in response to abiotic stresses and hormonal applications in foxtail millet.

摘要

植物类凝集素/类凝集素受体样激酶（MRLKs）在植物的整个生命周期中发挥着关键作用。在此，我们从谷子中鉴定出23个SiMRLK基因。所有SiMRLK基因均根据其在谷子基因组中的染色体分布进行命名，并基于系统发育关系和结构特征分为五个亚家族。共线性分析表明，基因复制事件可能参与了谷子中SiMRLK基因的进化。通过qRT-PCR评估了23个SiMRLK基因在非生物胁迫和激素处理下的表达谱。SiMRLK1、SiMRLK5、SiMRLK9和SiMRLK11的表达受到干旱、盐和冷胁迫的显著影响。外源脱落酸（ABA）、水杨酸（SA）、赤霉素（GA）和茉莉酸甲酯（MeJA）也明显改变了SiMRLK1、SiMRLK5、SiMRLK9和SiMRLK11的转录水平。这些结果表明，在谷子中，SiMRLK基因的转录模式在响应非生物胁迫和激素处理时表现出多样性和复杂性。
