Transcription profiling of Arabidopsis dormant versus active axillary shoot apical mersitems

ABSTRACT: The aim of this study is to identify genes differentially expressed during the transition between dormancy and activity in axillary shoot apical meristems. We have chosen to study this by comparing mRNA populations from the axillary buds of the auxin over-responding, apically dominant axr3-1 mutant of Arabidopsis,with those from the axillary buds of the auxin resistant axr1-12 bushy mutant. Preliminary investigation using cDNA AFLP has been successful in identifying differentially expressed transcripts in the buds of these two genotypes, thus demonstrating the importance of this study, however this is a time consuming procedure. Axillary buds from axr3-1 are seen to arrest at an early stage when the buds are approximately 2mm long and harvested at this point. Buds of a similar size were ha
