De novo shoot organogenesis during plant regeneration.

Summary of "De novo shoot organogenesis during plant regeneration."

Plants exhibit remarkable regeneration capacity, ensuring developmental plasticity. In vitro tissue culture techniques are based on the plant regeneration ability and facilitate production of new organs and even whole plant from explants. Plant somatic cells can be reprogrammed to form a pluripotent cell mass called callus. A portion of pluripotent callus cells gives rise to a fertile shoot via de novo shoot organogenesis (DNSO). Here, we reconstitute the shoot regeneration process with four phases, including pluripotency acquisition, shoot promeristem formation, establishment of confined shoot progenitor, and shoot outgrowth. Additionally, other biological processes, including cell cycle progression and reactive oxygen species metabolism, which further contribute to successful completion of DNSO, are also summarized. Overall, this study highlights recent advances in the molecular and cellular events involved in DNSO and regulatory mechanisms behind key steps of DNSO.

Medical and Biotech [MESH] Definitions

Transformative processes which occur in cells and tissues to produce differentiated plant organs.

Molecule produced in plant leaves that acts like a hormone by inducing flowering in the shoot apical meristem of buds and growing tips.

Procedures for enhancing and directing tissue repair and renewal processes, such as BONE REGENERATION; NERVE REGENERATION; etc. They involve surgically implanting growth conducive tracks or conduits (TISSUE SCAFFOLDING) at the damaged site to stimulate and control the location of cell repopulation. The tracks or conduits are made from synthetic and/or natural materials and may include support cells and induction factors for CELL GROWTH PROCESSES; or CELL MIGRATION.

A preparation consisting of PLATELETS concentrated in a limited volume of PLASMA. This is used in various surgical tissue regeneration procedures where the GROWTH FACTORS in the platelets enhance wound healing and regeneration.

A cosmetic technique that uses PLASMA GASES in therapeutic treatment to help achieve skin REJUVENATION or REGENERATION and delay SKIN AGING.
