Transcription profiling by array of Saccharomyces cerevisiae strain VL3 with or without the the co-inoculation of a second yeast species, Pichia kluyveri (PKKR1).

ABSTRACT: Replicate cultres of Saccharomyces cerevisiae strain VL3 (a commercial wine strain) were inititaed with and without the the co-inoculation of a second yeast species, Pichia kluyveri (PKKR1). In addition replicate cultures of Pichia kluyveri were initiated. The media for all cultures was sterile Sauvignon blanc grape juice. Triplicates of each treatment were destructively harvested at days 2, 9 and 16 of fermentation and RNA extracted. RNA from S. cerevisiae could not be preferentially extracted from co-ferments. P. kluyveri genome has not been sequenced and so homology to S. cerevisiae probes on the array could not be accurately estimated. We extracted RNA from the P. kluyveri single ferments and hybridised them to the S. cerevisiae arrays to control for this. These species diverged over 1
