The dearth of pseudogenes suggests that sequence clusters are maintained by selection for high gene-copy number, perhaps due to selection for high expression rates.

In an effort to increase stress tolerance, there have been attempts to artificially increase the concentration of GB in plants by selection for high accumulating species, genetic engineering, or exogenous application.

This is consistent with the notion that both characters are affected by selection for high rates of gene expression, although the relative placement of slow and intermediate growers indicates that this selective pressure is not the only factor at play.
