Fig. 6From: Gut microbiota is associated with the effect of photoperiod on seasonal breeding in male Brandt’s voles (Lasiopodomys brandtii)Summary on the changes of physiological indices in donor voles (solid arrow) and recipient voles (dashed arrow). Upward/down arrow shows an increase/decrease in hormone levels or gene expression under SD or F-SD conditions as compared to LD or F-LD treatment. “-” indicates no change. MT, melatonin; GnRH, gonadotropin-releasing hormone; FSH, follicle-stimulating hormone; LH, luteinizing hormone; T, testosterone; Dio2, iodothyronine deiodinase 2; Dio3, iodothyronine deiodinase 3; Dio2/Dio3, the ratio of Dio2 to Dio3 expression; Kiss-1, Kisspeptin-1; GPR54, G-protein-coupled receptor 54; GnRH, gene which encode gonadotropin-releasing hormone; Rfrp-3, RFamide-related peptide 3; Stra8, stimulated by retinoic acid 8. LD, long-day photoperiod (16L: 8D); SD, short-day photoperiod (8L: 16D); F-LD, recipients with transplantation of gut microbiota from LD donor voles; F-SD, recipients with transplantation of gut microbiota from SD donor volesBack to article page
