THE EFFECT OF MUTATIONS IN THE GENES SIGNALING OF AUKISNS <i>TIR1</i>, <i>GPA1</i>, <i>AGP1</i> AND <i>AXR2</i> THE BRANCHING ROOTS IN THE ROOT SYSTEM OF <i>ARABIDOPSIS THALIANA</i> (L.) HEYNH
The features of the root system structure in plants mutant lines tir1-1, gpa1-3, agb1-2 and axr2-1 Arabidopsis thaliana, violation of forming lateral roots were explored. There are two groups of branching of the roots that alter the signaling of auxins: mutations reducing the branching degree of the roots and mutations increasing the order of the roots branching. The first group includes mutations tir1-1 and gpa1-3. The second group includes mutations agb1-2 and axr2-1.
