英文摘要 | Ethanolamine kinase (ATP: ethanolamine O-phosphotransferase, EC 2.7.1.82) catalyzes the committed step of phosphatidylethanolamine synthesis via the CDP-ethanolamine pathway. The functions of eki genes that encode ethanolamine kinase have been intensively studied in mammalian cells, fruit flies and yeast. However, the role of the eki gene has not yet been characterized in filamentous fungi. In this study, Treki1, an ortholog of Saccharomyces cerevisiae EKI1, was identified and functionally characterized using a target gene deletion strategy in Trichoderma reesei. A Treki deletion mutant was less sensitive to cell wall stressors calcofluor white and Congo red and released fewer protoplasts during cell wall digestion than the parent strain QM9414. Further transcription analysis showed that the expression levels of five genes that encode chitin synthases were drastically increased in the Delta Treki1 mutant. The chitin content was also increased in the null mutant of Treki1 comparing to the parent strain. In addition, the Delta Treki1 mutant exhibited defects in radial growth, conidiation and the accumulation of ethanolamine. The results indicate that Treki1 plays a key role in growth and development and in the maintenance of cell wall integrity in T. reesei. |
