What is it about?
Silicon, the second most abundant element of the Earth's crust, has beneficial role to alleviate stress conditions in crops. We show that silicon application in soluble form improves the biochemical and physical defenses of wheat, as indicated by induction of stress hormones, transporter genes, antioxidants and pigment stoichiometry.

Why is it important?
Salinity impedes plant growth and productivity, thereby improving salt resistance in crops is critical for sustainable crop production in salt effected marginal lands. We show for the first time that silicon application leads to changes in photosynthetic pigments, indicative of photoprotection by virtue of "mechanically shielded leaf microenvironment".
Perspectives
I believe the aim of this study is in line with the demand of our society from science to offer practical solutions for pressing problems of today and future. This study contributes to develop our understanding on the interaction between plants and soil, with reference to the role of soil elements to improve salt-stress resistance
