Hypocotyls from Antirrhinum majus L. were excised at 2 weeks of age from seedlings grown under a 16-hour photoperiod or continuous darkness. Explants were cultured on modified Murashige-Skoog (MS) medium containing 0, 0.44, 2.22, 4.44, 8.88, or 44.4 μm BA to investigate adventitious shoot formation. Excised hypocotyls from eight commercial cultivars, three inbred lines, and an F1 hybrid between two of the inbreds were cultured on MS medium containing 2.22 μm BA to assess genotypic effects on adventitious shoot formation. The influence of seedling age was assessed by excising hypocotyls from seedlings at 6, 10, 14, 18, 22, 26, or 30 days. Optimal conditions for adventitious shoot formation on excised hypocotyls included: seedling growth in a lighted environment, use of hypocotyls from 10-day-old seedlings, and culture on medium containing 2.22 μm BA for 3 weeks. Under these conditions, up to a 5-fold improvement in number of shoots per hypocotyl over previous studies was achieved. Adventitious shoot formation was genotype-dependent and appeared to be a dominant trait. Chemical name used: N6-benzyladenine (BA).

“…In addition to seed storage, tissue-culture methods for cucurbits are relatively well developed (see Molina and Nuez 1996), and pollen-storage methods, primarily for Citrullus, are being developed (Sugiyama, Morishita and Nishino 2002b).…”

“…In contrast to pollen storage, tissue-culture methods for cucurbits are relatively well-developed, although organogensis and regeneration success can be strongly influenced by genotype (see Molina and Nuez 1996). Protocols for embryo and ovule culture were recently reviewed by Skalova, Lebeda, and Navratilova (2004) and those for protoplast culture by Gajdova, Lebeda, and Navratilova (2004).…”

“…It is common knowledge that regeneration is infl uenced by genotype in some species. Segregation for regeneration studies indicate regeneration is under genetic control in melon (Cucumis melo L.) (Molina and Nuez, 1996), tomato [Lycopersicon esculentum Mill. and L. peruvianum (L.) Mill.]…”

Developmental anatomy of adventitious shoot formation in vitro from snapdragon (Antirrhinum majus L.) hypocotyls was investigated using two inbred lines, the most (R) and least (NR) regenerative lines selected from screening (Schroeder and Stimart, 1999). Time course analysis indicated cell division in the most regenerative line occurred first in one or a small number of epidermal cells with periclinal and anticlinal divisions within 2 days of placing hypocotyls on induction medium. Subsequently, cortical then vascular cells were recruited beneath the dividing epidermal cells. Once shoots formed, their vascular system was continuous with the original hypocotyl explant. The least regenerative line had no cell division directed towards organogenesis through 6 days. Shoot formation on snapdragon hypocotyls was adventitious in origin, by direct organogenesis and genotype dependent.
