The ttk gene structural characteristics of Sogatella furcifera and its expression level in nymphs
) gene transcription products are important transcription factors, which can regulate the development, differentiation and sexual behavior of organisms. In this study, a 1 657 bp cDNA sequence of
ttk
was identified from the transcriptome database of
Sogatella furcifera
. The open reading frame is 1 377 bp in length and encodes a protein composed of 458 amino acids. It has a typical BTB domain and a zinc finger structure. The phylogenetic tree shows that
ttk
of
S. furcifera
is closely homologous to that of
Zygaena filipendulae
,
Cimex lectularius
and
Nilaparvata lugens
. Quantitative detection results showed that the transcriptional level of
ttk
was higher in the 1st instar nymphs, but decreased to a lower level in the 2nd instar nymphs. From the 3rd instar,
ttk
expression increased gradually with instar growth, and at the 5th instar nymphs,
ttk
expression was more than twice as high as that in the 3rd instar nymphs. This is the first in detail investigation on
ttk
gene structure of white backed planthopper, and the results provide a foundation for further and function and regulation study of
ttk
gene, in the growth and development of rice planthopper in the future.
