Fig 5. Brv1 is involved in the UV-induced shift of behavioral responses to cold.

(A-C) Percent of (A) CT, (B) US or (C) BR responders to the cold probe (10°C) 24 hours after UV in TRP channel mutant for Brv1 over a relevant deficiency (Df). (D-F) Percent of (D) CT, (E) US, or (F) BR responders to the cold probe 24 hours after UV in larvae expressing brv1-RNAi transgenes in class IV or chordotonal neurons. (A-F) n = 3 sets of 20 larvae averaged ± s.e.m., except for (E) where Ch-Gal4>brv1-RNAi was an n = 20 larvae (therefore, SD not shown). Stats: two-tailed Fisher’s exact test, * = p < 0.05, ** = p < 0.001. Black asterisks indicate statistical analysis between mock and UV groups for a given genotype. Red asterisks indicate statistical analysis between (A-C) UV-treated w¹¹¹⁸ and mutant, or (D-F) UV-treated Gal4 alone and RNAi. NS = no significance between UV and mock of same genotype.
