Abstract Vitamin B6 induces in vivo as well as in vitro the appearance of a puff at region 2–48C in Drosophila hydei. At concentrations of 10−2 M or lower, region 2–48C is the only region responding to vitamin B6 provided that oligomycin is present in the incubation medium. Pyridoxal phosphate and pyridoxamine phosphate supplied to medium containing oligomycin induce upon incubation of salivary glands a larger puff at 2–48C. — Puff 2–48C produces large quantities of a unique RNP-product; globular 140–220 Å particles which aggregate to stable complexes of 0.1–0.2 μ in diameter. Upon continuous in vitro incubation with vitamin B6, puff 2–48C becomes loaded with these aggregates which have never been observed in any other puff of Drosophila hydei.
