Morpho-histology of co-occurrence of somatic embryos, shoots, and inflorescences within a callus of Limonium 'Misty Blue'.

This is the first attempt to report the co-occurrence of somatic embryos, shoots, and inflorescences and their sequential development from stem cell niches of an individual callus mass through morpho-histological study of any angiosperm. In the presence of a proper auxin/cytokinin combination, precambial stem cells from the middle layer of a compact callus, which was derived from the thin cell layer of the inflorescence rachis of Limonium, expressed the highest level of totipotency and pluripotency and simultaneously developed somatic embryos, shoots, and inflorescences. This study also proposed the concept of programmed cell death during bipolar somatic embryo and unipolar shoot bud pattern formation.

Direct Shoot From Root and True-to-Type Micropropagation of Limonium "Misty Blue" in Partially Immersed Culture on an Aluminum Mesh Raft.

Commercial plant tissue culture now primarily serves the ornamental horticulture industry. The main pillars of the commercial tissue culture business are scalability of production, cost reduction, limited labor involvement, high quality, and genetic homogeneity of propagated plants. Based on these requirements, the current protocol employs a partially immersed liquid culture medium supported by a flexible aluminum mesh raft with a wire stand to facilitate shoot organogenesis from the horizontally placed root explants and hold the plants upright for shoot multiplication and rooting of Limonium Misty Blue.
