Tandem repeats (TRs) are genomic regions that tandemly change in repeat number, which are often multiallelic. Their characteristics and contributions to gene expression and quantitative traits in rice are largely unknown. Here, we survey rice TR variations based on 231 genome assemblies and the rice...
Set this trigger as the first step in your flow when you want to receive events from Businessmap. Your next action should be a "Condition" check, where you will add a filter on "event" and proceed only if the event type matches the one you are interested in. Here you can find a ...
