Defining a transcriptome

I'm working with CLC to map Illumina paired end data from various plant varieties against either a CDS set or an annotated genome, depending on the species, and so to determine tissue transcript expression levels.

Clearly a few mapped reads cannot constitute true transcript expression, so my question is whether there is a generally accepted cutoff filter, based on RPKM or something else that can be used to define the transcriptome for that sample?

thanks in advance

hmmm.., not a lot of interest in answering this I see..

However tI hve just found an article that could help address this;
