Abstract
Barley seedlings homozygous both for the xantha-135 and tigrina-d12 mutation accumulate magnesium protopophyrins and other precursors of chlorophyllide constitutively in darkness. The homozygous double mutant xantha-f10, tigrina-O34 produces protoporphyrin constitutively. These results provide evidence for the control of chlorophyllide synthesis in higher plants through the products of regulatory genes in the nucleus.Keywords
