Schematic representation of constructs used for transformation. Constructs used for gene silencing by RNAi are in the green-shaded box, those for complementation tests are in the yellow-shaded box, and ones for overexpression are in the blue-shaded box. Short vertical lines represent the SNP: red, T; black, G; green, A. Triangle marks the 65-bp deletion at P6 marker in MH63. Dotted lines indicate omitted genome sequences. Arrow with asterisk indicates the cleavage site of miR2118.
