Hi all

I'm doing denovo RNAseq on a non-model plant under abiotic stress. I've done kegg enrichment for DE transcript by KAAS. But my results showed that in some cases there are several transcripts for a K-identifier or enzyme that can be the isoforms of a different gene or single gene based on the assembeled transcripts id. Even in some cases, the transcripts related to a id k showed a different expression pattern (up and down) How can these results be justified? can these transcripts be different members of gene family or result of alterenative splicing? thanks a lot
