The RT\u2010PCR technique was used to investigate the expression of the arylalkylamine <jats:italic>N<\/jats:italic>\u2010acetyltransferase (AA\u2010NAT) and melatonin receptor genes during development of the pineal glands isolated from Japanese quail (<jats:italic>Coturnix coturnix japonica<\/jats:italic>) embryos incubated from 3 days on until hatching (17 days), and in some organs (pineal, brain hemisphere, eye, leg, heart) of the 3\u2010day\u2010old quail embryo. It was shown that two phases of AA\u2010NAT expression are observed during pineal gland development. The first, embryonic\u2010type phase, lasts from the beginning until 7\u201310 days of incubation, and is marked by the presence of two RT\u2010PCR products for AA\u2010NAT: the shorter mature form without intron (238 bp), and the longer form (323 bp) containing an unprocessed intron of 85 bp. The second, adult\u2010type phase is characterized by the presence of a single mature transcript, containing no intron; it starts from 7 to 10 days of incubation and lasts until hatching and in the adult pineal. The duration of this transition time from the embryonic to the adult transcription pattern in the quail pineal gland from 7 to 10 days of incubation we attribute to asynchronic embryo development, because quail chicks usually hatch between the 16th and 19th day of incubation. Analysis of the AA\u2010NAT protein sequences for chick and quail (GeneBank accession no. U 46 502 and AF 007 068, respectively) revealed their perfect homology with the part of protein read from the sequence present in the adult\u2010type phase of the pineal gland (the RT\u2010PCR product of 238 bp). The presence of the intron (in the 323 bp RT\u2010PCR product, accession no. AY 197 460) in the embryonic\u2010phase of the pineal gland changes the reading frame of the mRNA sequence and the hypothetical resulting protein loses its homology with the chick and quail AA\u2010NAT enzyme starting with 105th amino acid of the complete chick AA\u2010NAT protein comprising 205 amino acids (accession no. U 46 502). In the whole embryos at stages 1\u20138 (according to the Hamburger\u2013Hamilton classification) both RT\u2010PCR products with and without intron were consistently found, and individual tissues from 3\u2010day\u2010old embryos also produced two AA\u2010NAT products, i.e., the expression was of the embryonic\u2010type. At the time of transition from the embryonic to the adult AA\u2010NAT transcription pattern, in 7\u201311\u2010day\u2010old embryos, all three melatonin receptor transcripts (mel\u20101a, mel\u20101b, and mel\u20101c) were observed in the pineals, without consistent modifications of the band intensity. In the adult pineal, a single mature AA\u2010NAT transcript was present as well as all three melatonin receptor transcripts, usually with preferential expression of the mel\u20101a band. The transition time from the embryonic to adult AA\u2010NAT expression pattern coincides well with the acquisition of functional activity and the appearance of melatonin synthesis in the embryonic pineal reported for chicken, as related to quail. We suggest that the change in transcription pattern of the <jats:italic>AA<\/jats:italic>\u2010<jats:italic>NAT<\/jats:italic> gene may reflect another, still unknown mechanism of regulating AA\u2010NAT activity during ontogenesis, at the level of mRNA processing, whose specificity (or not) for embryonic development we wish to establish in the future.
