Is Coefficient of Variability (CV) positively correlated with root mean squared error (RMSE) in every case??

My data for fungicide treated replication shows higher RMSE and R-square but less CV compared to the untreated replication for a regression between vegetation indices and yield. How correct is it?...

How do I find out the flanking ends or the complete genome sequence of a given sequence that I have obtained from a PCR product?

The organism is Streptomyces but the exact strain is not known and hence the sequence. So after sending the PCR product for sequencing we have the part of the whole sequence that contains the gene...
