Abstract

In this work we present a study of the genetic control of flower development in common buckwheat (Fagopyrum esculentum) based on the expression analysis of FesAG, FesLFY and FesAP1 - genes orthologous to those controlling flower development in Arabidopsis thaliana - in wild type buckwheat and in mutants fagopyrum apetala, tepal-like bract, green perianth. In the fagopyrum apetala mutant, characterised by the conversion of tepals into carpelloid organs, the expression of FesAG is increased what is consistent with the current knowledge based on the studies of model plant species. In another mutant - green perianth - characterised by partial conversion of flower into inflorescence, we revealed an increased expression of FesAP1. The latter is an unexpected result contradicting current models based on the study of Arabidopsis thaliana. Our data suggest a significant difference between the genetic control of flower development in Fagopyrum and in Arabidopsis.
