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.
