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.
