N2 - CLE peptides (CLAVATA3/ENDOSPERM SURROUNDING REGION) are signal molecules or plant peptide hormones that play an important role in regulation of development of various meristems governing the expression of WOX (WUSCHEL-RELATED HOMEOBOX) genes. In particular, CLE peptides belonging to a small TDIF (Tracheary Element Differentiation Inhibitory Factor) group are responsible for the operation of gene WOX4 controlling the development of cambium and the conducting system. We looked into the role of CLE41 peptide from the TDIF group in the development of storage root in two species of the genus Raphanus: cultivated radish (Raphanus sativus var. radicula Pers.) that is a popular root crop with a storage root and its ancestor wild radish (Raphanus raphanistrum L.) where storage parenchyma of the root is poorly developed. It was shown that overexpression of gene RsCLE41 and plant treatment with exogenous peptide CLE41 influenced the development of cambium and xylem in the roots of R. sativus and R. raphanistrum and affected expression of the genes from different groups. One could say that peptide CLE41 activates expression of the genes whose homologues in arabidopsis play a key role in the maintenance of cambium (RsWOX4, RsWOX14, RsHAM4, and RsCYCD3). In the storage root of radish, peptide CLE41 activates proliferation of cambium cells reducing the amount of one of the xylem’s elements (lignified parenchyma). The obtained results point to an important role of CLE41 in the development of storage root in radish.
