Abstract

Adventitious root formation is a key step in vegetative propagation of woody or horticultural species, and it is a complex process known to be affected by multiple factors. The process of roots development could be divided into three stages: root induction, root initiation, and root protrusion. Phytohormones, especially auxin, played an essential role in regulating roots developments. This review focused on recent advances in the research of plants rooting genomics and proteomics, including auxin biosynthesis, metabolism, transport, and signaling pathway which are involved in modulating plants rooting and the significances of proteomics on research the differences of rooting ability.

Key words: Auxin, molecular mechanism, genomics, proteomics, rooting.
