Abstract:The technique of mRNA fingerprinting was used to isolate flower-specific cDNAs in the oil palm. Differences in the RNA populations between vegetative tissue (leaf) and inflorescences at various stages of flower development were examined using 18 primer combinations. A total of 16 flower-specific cDNAs were identified, of which 15 were successfully re-amplified. Reverse Northern analysis confirmed that 8 of the 15 cDNAs appeared to truly represent differentially expressed mRNAs in flowering tissues. Northern blot analysis subsequently showed that 5 of the clones are preferentially or exclusively expressed in the flowering tissues of oil palm.
