Features inheritance of root system Arabidopsis thaliana (L.) Heynh. the interaction of genes CTR1 AND ALF3, NPH4 and IAR2

SUMMARY. The results of study interaction of genes CTR1, ALF3 and NPH4, IAR2 inheritance attributes of the root system Arabidopsis. It is set that there is a recession epistasis in the second generation of crossing of plants mutant lines ctr1-1 × alf3-1 (alf3-1 alf3-1 > CTR1_). At crossing of plants mutant lines nph4-1 × iar2-1 there is polymeric co-operation of genes NPH4 and IAR2 in the generation of F2.
