The induction of rooting in microshoots of Zingiber officinale cvs. Suprava, Turia local, Suruchi and V3S18 was achieved on half-strength basal Murashige and Skoog's medium supplemented with 0.5-1.0 mg/l either indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA) and 2% (w/v) sucrose within 7-9 days of culture. Rooting was inhibited when the microshoots were cultured under higher concentra...

Peroxidase and chitinase activities were measured in rnotsi of Eucalyptus ghhulus spp. bicustata {Wdid. et aL) Kirkp, during colonization by Pisolithus sp. isolated from under Eucalyptus. Ten fungal isolates, ranging from poor to good root colonizers, were selected to represent a range of ectomycorrhizal aggrfssi\'ity. The induction of chitinases and peroxidases was strongly related to the aggr...

The development of an efficient protocol for successful hairy root induction by Agrobacterium rhizogenes is the key step toward an in vitro culturing method for the mass production of secondary metabolites. The selection of an effective Agrobacterium strain for the production of hairy roots is highly plant species dependent and must be determined empirically. Therefore, our goal was to investig...

Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...

GF677 rootstock (peach ×almond) is an important rootstock for peach. It was produced by Bernhard in French at Grand Farad Research Centre in 1965. The present study focused on the effect of some PGRs on propagation and root induction on GNH medium as part of providing an applicable protocol for micro-propagation of mentioned rootstock. Results indicated that BAP at concentration of 0.5 mg/l plu...

In eukaryotes, the control of cell cycle progression is exercised by heteromeric protein kinase complexes composed of a cell cycle-dependent, kinase-related subunit (Cdc2) and a cyclin subunit. To explore the possibility that cyclin transcription plays a role in the developmental regulation of cell division, we examined the spatial and temporal expression of a cyclin gene (cyc1At) in Arabidopsi...

The aim of this study was to evaluate the microbial distribution in the root canal system after periapical lesion induction in dogs' teeth using different methods. Fifty-two root canals were assigned to 4 groups (n=13). Groups I and II: root canals were exposed to the oral cavity for 180 days; groups III and IV: root canals were exposed for 7 days and then the coronal openings were sealed for 5...
