Previous studies have indicated the phosphoinositide and phospholipid signaling pathways play a key role in plant growth, development and responses to environmental stresses. However, little is known about the phosphoinositide and phospholipid signaling pathways in maize (Zea mays L.). To better understand the function of genes involved in the phosphoinositide and phospholipid signaling pathways in maize, the cDNA sequences of ZmPIS2, ZmPLC2, ZmDGK1, ZmDGK2 and ZmDGK3 were obtained by RACE (rapid amplification of cDNA ends) or in silico cloning combined with PCR. RT-PCR analysis of cDNA from five tissues (roots, stems, leaves, tassels, and ears) indicated that the expression patterns of the five cDNAs we isolated as well as ZmPIS, ZmPLC, ZmPLD varied in different tissues. To determine the effects of different environmental conditions such as cold, drought and various phytohormones (abscisic acid, indole-3-acetic acid and gibberellic acid) on gene expression, we analyzed expression by Real-Time (RT-PCR), and found that the different isoforms of these gene families involved in the phosphoinositide and phospholipid signaling pathways have specific expression patterns. Our results suggested that these genes may be involved in the responses to environmental stresses, but have different functions. The isolation and analysis of expression patterns of genes involved in the phosphoinositide and phospholipid signaling pathways provides a good basis for further research of the phosphoinositide and phospholipid signaling pathways in maize and is a novel supplement to our comprehension of these pathways in plants.
