Expression and Functional Characteristics of Genes in the Globodera rostochiensis Woll. Potato Cyst Nematode at Different Stages of Its Life Cycle

Аннотация

The expression of the Ams-1, Pel-1, Eng-1.4, Cle, VAP-1, SPRYSEC-1, Tpx, and Gpx genes was studied in Globodera rostochiensis juveniles at early stages of the life cycle. Low gene activity was registered in juveniles inside the cyst. It was established that the transition to active life is accompanied by transcriptome activation. It was found that when susceptible plants (characterized by slow development of protective reactions) act as a host, gene expression is increased in the juveniles depending on the stage of development; this provides a successful passage of the nematode life cycle. A decreased gene transcription is registered in the juveniles in the case of plants treated with short-term temperature drops (DROP treatment); this can lead to the suppression of nematode development.
