Аннотация:It is well known that high auxin concentration inhibits root growth, but lower ones can change
plant root developmental program. PIN transporters that are responsible for the auxin transport
and its redistribution certainly are involved in these phenomena. However it is not so clear what
do affect auxin transporters? Last decade significance of the CLE peptides especially in plant
root growth and development has been shown in plenty of scientific papers. The role of the
first one established CLE-like peptide - CLV3p is clear in shoot apical meristem maintenance,
however the mechanisms why it stops the root growth are not so clear yet. We have tested
the well-established concentration of 1μM chemically synthesized dodecaepeptide CLV3-
analog on distribution and fluorescent intensity of the PIN1:GFP, PIN2:GFP, PIN3:GFP in the
primary root of the Arabidopsis. We have observed that CLV3 dodecapeptide do affect PINs.
