Comment on mRNA-Sequencing Analysis Reveals Transcriptional Changes in Root of Maize Seedlings Treated with Two Increasing Concentrations of a New Biostimulant.

Overpopulation is already a reality, and the need for alternative technologies to meet a continuously increasing food demand has been much discussed around the world. In addition, soil decreasing fertility and desertification are obstacles that we will need to be overcome to increase crop productivity with a much-reduced dependence upon inorganic fertilizers. In this context, protein hydrolysates has emerged as an important strategy to reduce the use of inorganic fertilizers, whose applications as biostimulants for plant growth have shown very promising results.
