RNA interference of a trehalose-6-phosphate synthase gene reveals its roles during larval-pupal metamorphosis in Bactrocera minax (Diptera: Tephritidae)

Invertebrate Trehalose-6-Phosphate Synthase Gene: Genetic Architecture, Biochemistry, Physiological Function, and Potential Applications

“…In recent years, several approaches have been applied to study the trehalose synthesis genes TPS and TPP . Their special functions in molecular mechanisms underlying different stresses and even in the regulation of chitin synthesis have been described in insects and other invertebrates (Chen et al, 2002 , 2003 ; Tang et al, 2010 ; Chen and Zhang, 2015 ; Shi et al, 2016 ; Xiong et al, 2016 ; Yang et al, 2017 ), taking advantage of their ability to adapt to stress conditions (Chen and Haddad, 2004 ; Qin et al, 2012 ; Tang et al, 2014b ; Guo et al, 2015 ). On the one hand, an increasing number of TPS genes are being identified and cloned from different insects and other invertebrate species.…”

“…The first insect TPS gene was cloned in Drosophila (Chen et al, 2002 ; Chen and Haddad, 2004 ), and the induction of TPS1 gene expression was shown to increase tolerance to anoxia (Chen et al, 2002 ). Subsequently, insect TPS genes were cloned from Helicoverpa armigera (Xu et al, 2009 ), Locusta migratoria manilensis (Cui and Xia, 2009 ), Spodoptera exigua (Tang et al, 2010 ), Nilaparvata lugens (Chen et al, 2010b ), Catantops pinguis (Tang et al, 2011 ), Ctenocephalides felis (Kern et al, 2012 ), Harmonia axyridis (Qin et al, 2012 ), Blattella germanica (Chen and Zhang, 2015 ), Delia antiqua (Guo et al, 2015 ), Leptinotarsa decemlineata (Shi et al, 2016 ), Bactrocera minax (Xiong et al, 2016 ), and other organisms. Moreover, two TPS genes have been found in B. germanica, Tribolium castaneum , and Aphelenchoides besseyi , and three TPS genes have been found in Ascaris suum and N. lugens (Figure 1A and Table 1 , Shen, 2017 ).…”

Transciptomic Analysis of Larval Fat Body of Plutella xylostella under Low Temperature

“…Trehalose는 혈림프에서 발견되는 주요 당이며, 1차적인 에너지원과 chitin 합성의 시작물질로 알려져 있다 (Xiong et al, 2016;Thompson, 2003). 지방체는 척추동물의 간과 비 슷한 역할을 하며, 대사중심으로써 trehalose-6-phosphate synthase를 이용하여 trehalose를 생산한다 (Kern et al, 2012).…”

Targeting the potassium ion channel genes SK and SH as a novel approach for control of insect pests: efficacy and biosafety

“…This technology can be seen as an 'environmentally friendly' approach for the control of insect pests, with a high degree of specificity. 4 Many insect species from different orders, including Coleoptera, [5][6][7] Hemiptera, 8 Orthoptera, 9 Diptera 5,10,11 and Lepidoptera, [12][13][14][15] have been shown to be sensitive to dsRNA, although some species are far more sensitive than others. Previous studies have revealed that the Coleoptera are more susceptible to dsRNA compared to other arthropod orders, 16 while the Lepidoptera require higher concentrations of dsRNA.…”
