- Abstract:
- ... A protocol for large-scale propagation of Phragmites communis Trin. by adventitious bud formation and plant regeneration was established. Adventitious buds were induced through either the indirect pathway or the direct pathway from stem explants of Phragmites communis. In the indirect pathway, it was essential to decrease the level of 2,4-dichlorophenoxyacetic acid from 9.1 to 0.5 μμM to induce ad ...

- Abstract:
- ... Cryopreservation of African violet via encapsulation––dehydration, vitrification, and encapsulation––vitrification of shoot tips was evaluated. Encapsulation––dehydration, pretreatment of shoot tips with 0.3 M sucrose for 2 d followed by air dehydration for 2 and 4 h resulted in complete survival and 75%% regrowth, respectively. Dehydration of encapsulated shoot tips with silica gel for 1 h result ...

- Abstract:
- ... The cucurbit family includes a number of valuable crop species (melon, cucumber, squash/pumpkin, watermelon). Much of this review is concerned with transgenic resistance to viruses, shown to be the major application of biotechnology in the cucurbit family. Progress made with the production of transgenic cucurbit crops is discussed. Published data on field tests of transgenic cucurbits are reviewed ...

- Abstract:
- ... The effect of different sealing materials \[i.e., polyvinyl chloride (PVC) transparent film, and Parafilm (PARA)\] for Petri dishes was investigated on shoot regeneration from quince (Cydonia oblonga L.) ‘‘BA 29’’ leaf explants. Leaves were excised from proliferating shoot cultures, transversally scored, and placed with the abaxial side down in 60-mm Petri dishes containing 10 ml of Murashige and ...

- Abstract:
- ... To achieve reliable stable transformation of sweet potato, we first developed efficient shoot regeneration for stem explants, leaf disks, and petioles of sweet potato (Ipomoea batatas (L.) Lam.) cultivar Beniazuma. The shoot regeneration protocol enabled reproducible stable transformation mediated by Agrobacterium tumefaciens strain EHA105. The binary vector pIG121Hm contains the npt II (pnos) gen ...

- Abstract:

High-frequency embryogenesis systems were established for hybrid yellow-poplar (Liriodendron tulipifera××L. chinense) and hybrid sweetgum (Liquidambar styraciflua××L. formosana) by modifying a medium originally developed for embryogenic yellow-poplar cultures. Embryogenic cultures of both hybrids, consisting of proembryogenic masses (PEMs), were initiated from immature hybrid seeds on an induction ...

An elite aspen hybrid (Populus××canescens××P. grandidentata) was transformed with Agrobacterium tumefaciens strain EHA105 that harbored a binary vector (pBI121) carrying the nptII gene under the nos promoter and tandem rolB––uidA (GUS) genes with the CaMV 35S or heat shock promoter. Among 32 independent kanamycin-resistant plants, 25 plants were confirmed by polymerase chain reaction and Southern ...

- Abstract:
- ... A new protocol has been developed for the highly efficient somatic embryogenesis and plant regeneration of 10 recalcitrant Chinese cotton cultivars. Calluses and embryogenic calluses were induced on MSB1 medium containing the optimal combination of indolebutyric acid (IBA; 2.46 μμM) and kinetin (KT; 2.32 μμM). Up to 86.7%% of embryogenic calluses differentiated into globular somatic embryos 2 mo. ...

- Abstract:
- ... The effect of ventilation during the multiplication stage on the development of propagules from different clones of jojoba \[Simmondsia chinensis (Link) Schneider\] was investigated. Variation in the response to ventilation was due to genotype, the extent of ventilation, and to the period of exposure (transfer number). With intermediate ventilation treatments, propagules elongated to a greater ext ...

- Abstract:
- ... The capacity of cultured plant tissues and cells to undergo morphogenesis, resulting in the formation of discrete organs or whole plants, has provided opportunities for numerous applications of in vitro plant biology in studies of basic botany, biochemistry, propagation, breeding, and development of transgenic crops. While the fundamental techniques to achieve in vitro plant morphogenesis have bee ...

- Abstract:
- ... An efficient procedure for the in vitro propagation and cryogenic conservation of Syzygium francissi was developed. The maximum number of shoots per explant was obtained on a Murashige and Skoog (MS) medium supplemented with 4.5 μμM benzyladenine and 0.5 μμM indole-3-butyric acid (IBA). The in vitro-propagated shoots produced roots when transferred to MS medium containing IBA, indole-3-acetic acid ...

- Abstract:

Studies were carried out to evaluate sugarcane bagasse as an alternative to agar for micropropagation of apple clones to reduce the cost of micropropagation and improve the quality of the propagules. Significant improvement in the in vitro rooting process, coupled with cost reduction, were obtained by the use of sugarcane bagasse as a substitute for the traditionally used agar-gelled medium. The t ...
