Features of inheritance of Arabidopsis thaliana (L.) Heynh. root system: Interaction of genes CTR1 and ALF3, NPH4, and IAR2

Resumo

The results of studied interaction of genes CTR1, ALF3 and NPH4, IAR2 at the inheritance of the root system features of Arabidopsis were presented. A recessive epistasis was found in the second generation of crossing of plant mutant lines ctr1-1 × alf3-1 (alf3-1 alf3-1 > CTR1_). Crossing plant mutant lines nph4-1 × iar2-1 resulted in a polymeric cooperation of genes NPH4 and IAR2 in F₂ generation.
