Studies were followed by a transcriptome analysis of crown tissue of genotypes contrasting for Zn deficiency tolerance. In this study she highlighted the molecular mechanisms triggered by early Zn deficiency in crown tissue, through RNA sequencing of two contrasting groups of several Zn efficient and Zn inefficient genotypes. This method allowed her to 1) identify several novel and well-known Zn transporters involved in Zn retranslocation from the crown to the shoot and roots in response to Zn deficiency; 2) determine that Zn deficiency triggers the conversion of soluble sugars into starch; and 3) detect several candidate genes possibly conferring Zn efficiency, including a monosaccharide transporter, a Zn finger domain-containing protein, a gibberellin stimulated family protein and a plasma membrane polypeptide family protein. This work has been submitted and is under review in the Journal of Experimental Botany:
