Abstract
By optimizing the Mg2+ concentration, Taq enzyme dosage, SYBR Green I (SGI) concentration, and plate reading temperature in PCR system, we established the method for detecting the expression levels of nitrogen assimilation-related genes in rice by using RT-PCR technique. Based on this qualified method, we investigated the variations of OsAMT1.1 (one of nitrogen uptake genes) and OsGlt1 (one of nitrogen metabolism genes) expression levels in rice seedlings under conditions of varying nitrogen supply. The results show that by optimizing the parameters in the PCR system to fit the characters of target genes best, we can successfully quantify the low-abundant nitrogen transport and metabolism genes in rice quickly and exactly using fluorescence RT-PCR technique.
