Callus culture for biomass production of milk thistle as a potential source of milk clotting peptidases Electron. J. Biotechnol.
Cimino,Cecilia; Vairo Cavalli,Sandra; Spina,Francisco; Natalucci,Claudia; Priolo,Nora.
The objective of this work was the optimization of the conditions of in vitro culture for callus production of Silybum marianum (L.) Gaertn. (Asteraceae). Sections of cotyledons, previously disinfected by washing successively with ethanol 70º, NaClO (10% w/v) and Tween 20 (0.05% v/v) and rinsing with sterile distilled water, were used as explants. For its initial culture, B5 medium supplemented with BA and 2,4-D solidified with phytagel was used, and a 63% survival was achieved. To obtain callus, two solid media were assayed (S1 and S2) using B5 medium supplemented with growth regulators (BA and 2,4-D or NAA and BA, respectively). The calli were grown at 25ºC during 45 days in darkness. Growth kinetics was studied using S1 medium...

Callus induction and plant regeneration of the endemic Astragalus nezaketae in Turkey Electron. J. Biotechnol.
Erisen,Semiha; Yorgancilar,Mustafa; Atalay,Emine; Babaoglu,Mehmet; Duran,Ahmet.
A callus induction and plant regeneration protocol was developed from leaf and petiole explants of the endemic Astragalus nezaketae. Explants were cultured on Murashige and Skoog medium (MS) supplemented with different plant growth regulators (PGRs) [?-naphthaleneacetic acid (NAA), benzyladenine (BA), 2,4-dichlorophenoxyacetic acid (2,4-D), kinetin (Kin), thidiazuron (TDZ)]. The combinations and concentrations of PGRs were shown significant variations for the frequency of callus formation, appearence of callus and the potential of callus differentiation. NAA x BA have been found highly affective in callusing and plant regeneration. Other PGRs have not resulted in callus differentiation for shoot formation. The highest number of shoots (6/explants) was...

Embryogenic potential of the callus of gabirobeira, Campomanesia adamantium (Cambess) O. Berg Biological Sciences
Rossato, Marieli; Schumacher, Pedro Vitor; Costa Netto, Antônio Paulino da; Stein, Vanessa Cristina; Reis, Edésio Fialho dos; Vilela, Marlúcia Souza Pádua; Paiva, Luciano Vilela.
Campomanesia adamantium is a native plant species of Brazilian Cerrado with diverse economic potential and great medicinal importance. Its sexual propagation is impaired by the recalcitrance of its seeds, which prevents effective and profitable propagation. With the purpose of establishing commercial crops and minimizing the extractive use of vegetal resources, the aim of the present study was to induce embryogenic calli in nodal segments of gabirobeira, and to determine and characterize their embryogenic phase through the establishment of a growth curve based on cellular characteristics. Calli were induced using nodal segments inoculated in WPM culture medium without the addition of hormones (control) and with different concentrations of 2,4-D, IAA, IBA,...

Gene expression of a putative glutathione S-transferase is responsive to abiotic stress in embryogenic cell cultures of Cyclamen persicum Electron. J. Biotechnol.
Hoenemann,Claudia; Ambold,Juliane; Hohe,Annette.
Background: Cyclamen persicum is an economically important ornamental crop that is propagated exclusively through seeds as vegetative propagation using cuttings is not possible. Therefore a micropropagation method through somatic embryogenesis is of high interest; however the method suffers from low reliability concerning quality and quantity of the produced plantlets. A crucial step of the protocol is the removal of plant growth regulators (PGRs) that triggers embryo development. In order to get a better insight in this crucial step of the propagation process, a gene expression analysis has been set up using five different genes of glutathione S-transferases (GST) as these are known to be auxin responsive as well as stress reactive. Results: One out of...

Improved method for isolation of coupled mitochondria of Araucaria angustifolia (Bert.) O. Kuntze BABT
Mariano,André Bellin; Kovalhuk,Leonardo; Valente,Caroline; Maurer-Menestrina,Juliana; Pereira-Netto,Adaucto Bellarmino; Guerra,Miguel Pedro; Carnieri,Eva Gunilla Skare.
A method for the isolation of coupled mitochondria from the callus of Araucaria angustifolia is described for the first time. Mitochondria were isolated from embryogenic callus of A. angustifolia. They were metabolically active, able to sustain oxidative phosphorylation as shown by respiratory control ratio values, which were about 2.4 when respiring on succinate as substrate. Oxygen uptake experiments, using freeze-thawed disrupted mitochondria, showed the presence of alternative rotenone-insensitive NAD(P)H dehydrogenases, which were stimulated by Ca2+. The procedure now described for the isolation of A. angustifolia mitochondria is an important new tool, allowing the investigation of mitochondrial bioenergetics and metabolism and physiology of plants.

In vitro establishment and multiplication of the Normania triphylla (Lowe) Lowe BABT
Delmail,David; Labrousse,Pascal; Lesouëf,Jean-Yves; Le Hir,François; Autret,Jean-Luc; Botineau,Michel.
Normania triphylla is an endemic species from Madeira island (Portugal) extinct in the wild since 1991. The aim of this work was to culture the meristems of this species in vitro and to multiply its shoots in order to preserve this endangered species. The best results in terms of multiplication were obtained in Murashige and Skoog medium supplemented with 10 µM 6‑benzylaminopurine (BAP). The number of shoots, the number of nodes and the number of leaves were the most important in this medium. However, the best results concerning the total shoot length were obtained when BAP was not supplemented into the medium and in the presence of 5 or 7.5 µM 1-naphtalene acetic acid (NAA). This is the first report on the in vitro culture of N. triphylla which could...
