Shoot organogenesis from mulberry leaf tissue: origin and development of regenerated shoots

Direct shoot organogenesis induced from mulberry leaf tissue was observed histologically. In the initial stage of culture, small meristematic nodules were newly formed from subepidermal layer in the midrib and its adjacent zone of cultured leaf tissues, resulting in dome-like protrusions initiated on the adaxial leaf surface. These protrusions were elongated, from which leaf primordia were differentiated thereafter. In later stage, the cone-shaped cells were also differentiated in the outer surface of leaf primordia, and trichomes with a spheroidal head as well. In regenerated shoots, calcium deposition was observed in idioblasts that changed into rounded form. All of these histological features revealed the direct shoot organogenesis without taking a pathway through callus phase
