title: Genetic regulation of chlorophyll synthesis analyzed with mutants in barley.
abstract: Barley seedlings homozygous both for the xantha-1(35) and tigrina-d(12) mutation accumulate magnesium protopophyrins and other precursors of chlorophyllide constitutively in darkness. The homozygous double mutant xantha-f(10), tigrina-O(34) 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.
