When adult females of T. urticae enter diapause, their body color changes from yellowish-green to orange due to the accumulation of carotenoids. Carotenoids play several roles, including body coloration, light perception, and protection of biomolecules from oxidative stress. However, the relationship between body color changes and reproductive arrest associated with diapause remains unclear. To reveal the relationship between carotenoid accumulation and reproductive diapause, we analyzed the proteomic patterns in diapause and non-diapause induced females with a liquid chromatography tandem-mass spectrometry (LC-MS/MS). The result shows that phytoene desaturate (tetur01g11270) was highest in diapause induced females than other genes related to carotenoid biosynthesis. Using phytoene desaturate as a biomarker, we anticipate further investigation of the relationship between carotenoid accumulation and reproductive diapause in T. urticae.Thu Jul 30 00:00:00 BST 2026PXD07820732264
