Mitochondrial regulation of flower development

Abstract

Flower development in plants depends not only on a set of nuclear genes but also on the coordinate action of the mitochondrion. Certain mitochondrial genomes in combination with certain nuclear genomes lead to the expression of cytoplasmic male-sterility (CMS). Both mitochondrial genes that determine male-sterility and nuclear Restorer-of-fertility genes that suppress the male-sterile phenotype have been cloned. Lately, the interactions between mitochondrial and nuclear genes through retrograde signalling in CMS-systems have been dissected. Of special interest are the altered expression patterns of floral homeotic genes in certain CMS-systems. Here, we review the mitochondrial influence on flower development and give examples from CMS-systems developed in Brassica, Daucus Carota, Nicotiana tabacum and Triticum aestivum.
