Phospholipase C (PLC) is one of the main hydrolytic enzymes in the metabolism of phosphoinositide and plays an important role in a variety of signal transduction processes responding to plant growth, development, and stress. Although the characteristics of many plant PLCs have been studied, genes of maize have not been comprehensively identified. According to the study, five phosphatidylinositol-specific PLC (PI-PLC) and six non-specific PLC (NPC) genes were identified in maize. The PI-PLC and NPC genes of maize are conserved compared with homologous genes in other plants, especially in evolutionary relationship, protein sequences, conserved motifs, and gene structures. Transient expression of ZmPLC-GFP fusion protein in protoplast cells showed that are multi-localization. Analyses of transcription levels showed that were significantly different under various different tissues and abiotic stresses. Association analysis shown that some significantly associated with agronomic traits in 508 maize inbred lines. These results contribute to study the function of ZmPLCs and to provide good candidate targets for the yield and quality of superior maize cultivars.
磷脂酶C(PLC)是磷酸肌醇代谢中的主要水解酶之一,在响应植物生长、发育和胁迫的多种信号转导过程中发挥重要作用。尽管许多植物PLC的特性已被研究,但玉米的基因尚未得到全面鉴定。根据该研究,在玉米中鉴定出了5个磷脂酰肌醇特异性PLC(PI-PLC)和6个非特异性PLC(NPC)基因。与其他植物中的同源基因相比,玉米的PI-PLC和NPC基因是保守的,尤其是在进化关系、蛋白质序列、保守基序和基因结构方面。ZmPLC-GFP融合蛋白在原生质体细胞中的瞬时表达表明其具有多定位性。转录水平分析表明,它们在不同组织和非生物胁迫下存在显著差异。关联分析表明,在508个玉米自交系中,一些基因与农艺性状显著相关。这些结果有助于研究ZmPLC的功能,并为优良玉米品种的产量和品质提供良好的候选靶点。
