Sorry for not including this info first:

1) I would like to use total RNA from plants, probably contaminated with
carbohydrates, as the starting material

2) Primers are 25-30mers, Tm's ~55 degrees C in PCR

3) Targets are maximally 1.1 kB

4) Is a gene-specific primer for the RT step better/necessary with rTth?

5) (anything else I have forgotten to mention?)

Hope to hear replies soon!
