Tóm tắt

Tóm tắtĐặt vấn đề

Mycoparasitism, một lối sống trong đó một loại nấm ký sinh vào một loại nấm khác, có ý nghĩa đặc biệt khi con mồi là một tác nhân gây bệnh thực vật, cung cấp một chiến lược cho kiểm soát sinh học sâu bệnh trong việc bảo vệ thực vật. Có lẽ, các tác nhân kiểm soát sinh học được nghiên cứu nhiều nhất là các loài thuộc chi Hypocrea/Trichoderma.

Kết quả

Trong nghiên cứu này, chúng tôi báo cáo một phân tích về các chuỗi gen của hai loài kiểm soát sinh học Trichoderma atroviride (teleomorph Hypocrea atroviridis) và Trichoderma virens (trước đây là Gliocladium virens, teleomorph Hypocrea virens), và so sánh với Trichoderma reesei (teleomorph Hypocrea jecorina). Ba loài Trichoderma này thể hiện sự bảo toàn đáng chú ý của trật tự gene (78 đến 96%), và thiếu các yếu tố di động hoạt động có thể do đột biến điểm gây ra bởi sự lặp lại. Một số họ gene đã được mở rộng ở hai loài mycoparasitic so với T. reesei hoặc các ascomycetes khác, và được đại diện quá mức trong các vùng gen không đồng vị. Phân tích hệ phylogenetic cho thấy T. reeseiT. virens có nguồn gốc từ T. atroviride. Các gene đặc trưng cho mycoparasitism do đó phát sinh trong một tổ tiên chung của Trichoderma nhưng sau đó đã bị mất ở T. reesei.

Kết luận

Dữ liệu cung cấp sự hiểu biết sâu sắc hơn về mycoparasitism, và do đó thúc đẩy việc phát triển các chủng kiểm soát sinh học cải tiến cho việc bảo vệ thực vật hiệu quả và thân thiện với môi trường.
