We report the isolation of a bifunctional co¡ee ca¡eine synthase (CCS1)clone from co¡ee endosperm by reverse transcriptionpolymeras chain reaction (RT-PCR)and rapid ampli¢cation of cDNA ends (RACE)technique using previously reported sequence information for theobromine synthases (CTSs). The predicted amino acid sequences of CCS1are more than 80 UR - https://drive.google.com/file/d/1y6v-JV0a1C_uMO09hd04PBhHc4G-DIw_/view?usp=drivesdk ER -
