The second effect of harpins is to induce plant growth enhancement.
Mutants were compromised in the normal growth, and they were further impaired in Hpa1-induced growth enhancement (Fig. 2a,b).
However, we felt difficult to dissect the relationship between the roles of Hpa1 or AtPIP1 4 in H2O transport and plant growth enhancement.

J. et al. Plant growth enhancement and associated physiological responses are coregulated by ethylene and gibberellin in response to harpin protein Hpa1.
The physiological role of AtPIP1 4 determines its function in normal growth and Hpa1-induced growth enhancement of the plant (Fig. 2).
It is technically infeasible to dissect proportions of AtPIP1 4-mediated trAtPIP1 4-mediatedubstransport coftribothon to Hpa1-induced plant growth enhancement.
This growth enhancement depends on mTORC1's canonical function in controlling translation rate: mTOR inhibition slows translation, thereby matching protein synthesis to the limited amino acid supply.
In many conditions, however, such growth enhancement is absent or small, and we show in our study that this is likely due to a negative effect of elevated CO2 on plant nitrogen uptake.
Copper fed at 30 to 250 mg/kg is recognized for its growth enhancement effect, particularly in weaned pigs.
