In previous studies, TUB exhibited a stable expression, for example, Nilaparvata lugens for geographic population (Yuan et al., 2014), Sogatella furcifera at different developmental stages and under different temperature stress (An et al., 2016), Thitarodes armoricanus for the fungal infections (Liu et al., 2016), and Bemisia tabaci MED across all sample sets (Dai et al., 2017). Here, TUB is linked to fungal infectious disease.
