De novo shoot organogenesis (DNSO) is a procedure commonly used for the in vitro
regeneration of shoots from a variety of plant tissues. Shoot regeneration occurs on nutrient media
supplemented with the plant hormones cytokinin (CK) and auxin, which play essential roles in this
process, and genes involved in their signaling cascades act as master regulators of the different phases
of shoot regeneration. In the last 20 years, the genetic regulation of DNSO has been characterized in
detail. However, as of today, the CK and auxin signaling events associated with shoot regeneration
are often interpreted as a consequence of these hormones simply being present in the regeneration
media, whereas the roles for their prior uptake and transport into the cultivated plant tissues are
generally overlooked. Additionally, sucrose, commonly added to the regeneration media as a carbon
source, plays a signaling role and has been recently shown to interact with CK and auxin and to
affect the efficiency of shoot regeneration. In this review, we provide an integrative interpretation
of the roles for CK and auxin in the process of DNSO, adding emphasis on their uptake from the
regeneration media and their interaction with sucrose present in the media to their complex signaling
outputs that mediate shoot regeneration.
