In the present study, the effects of three ethylene inhibitors, silver nitrate (AgNO 3 ), silver sulfate (Ag 2 SO 4 ), and cobalt chloride (CoCl 2 ), on the morphogenic and biochemical responses in CAB-6P and Gisela 6 cherry rootstocks were investigated. In both rootstocks, AgNO 3 and Ag 2 SO 4 promoted shoot regeneration while CoCl 2 had such an effect only in Gisela 6. The rooting percentage of CAB-6P and Gisela 6 explants was diminished with AgNO 3 , Ag 2 SO 4 , and CoCl 2 . AgNO 3 increased root number (40 µM) and root length (50 µM) in the CAB-6P rootstock while it had an inhibitory effect in Gisela 6. Ag 2 SO 4 and CoCl 2 enhanced root length of Gisela 6 explants whereas Ag 2 SO 4 decreased root number and root length of CAB-6P explants. CoCl 2 at 10 µM in both rootstocks augmented root number whereas 20 µM CoCl 2 increased root length of CAB-6P microshoots. AgNO 3 , Ag 2 SO 4 , and CoCl 2 decreased leaf chlorophyll and carbohydrate content in CAB-6P rootstock. On the other hand, in Gisela 6, 10 µM AgNO 3 gave elevated chlorophyll levels and 20 µM AgNO 3 or 10-50 µM CoCl 2 raised leaf carbohydrate content. The three ethylene inhibitors led to elevated leaf proline levels in the CAB-6P rootstock, whereas in Gisela 6 the increase or decrease in leaf proline content was dependent on both type and concentration of ethylene inhibitor. An efficient micropropagation protocol was established for the CAB-6P and Gisela 6 cherry rootstocks using ethylene inhibitors.

In order to further increase the shoot regeneration frequency of Artemisia annua L., the effects of silver nitrate on this process was investigated in this study. Different concentration of silver nitrate was added to the shoot induction medium, which was MS basic medium containing 1.0 mg l −1 6-benzyladenine (6-BA) and 0.05 mg l −1 α-napthaleneacetic acid (NAA). When 2 mg l −1 silver nitrate was added to the shoot induction medium, the shoot induction frequency and shoot number per explants was significantly higher than that of the control (without silver nitrate). In addition, silver nitrate at all the tested concentrations could significantly reduce callus formation of the explants. Silver nitrate had also positive influence on shoot elongation in the first 20 days. Furthermore, silver nitrate did not affect the sensitivity of A. annua shoots to Kanamycin (KM); therefore, silver nitrate could be used to improve shoot regeneration capacity and frequency in A. annua genetic transformation.

“…Several studies have investigated different compounds that affect the biosynthesis of ethylene or its action on the morphogenic responses of in vitro cultures (Faria and Segura 1997;Naik and Chand 2003;Reis et al 2003;Ozudogru et al 2005;Santana-Buzzy et al 2006;Jha et al 2007;Joshi and Kothari 2007), but few have studied the possible effects of these compounds on polyamine biosynthesis. In order to verify this possible interaction, the objectives of the present study were to investigate the effect of ethylene on in vitro morphogenesis in hypocotyl-derived explants of passion fruit (Passiflora cincinnata Mast.…”

Ethylene and polyamine interactions in morphogenesis of Passiflora cincinnata: effects of ethylene biosynthesis and action modulators, as well as ethylene scavengers

Ethylene is a plant hormone that is of fundamental importance to in vitro morphogenesis, but in many species, it has not been thoroughly studied. Its relationship with polyamines has been studied mainly because the two classes of hormones share a common biosynthetic precursor, S-adenosylmethionine (SAM). In order to clarify whether competition between polyamines and ethylene influences in vitro morphogenetic responses of Passiflora cincinnata Mast., a climacteric species, different compounds were used that act on ethylene biosynthesis and action, or as ethylene scavengers. Treatment with the ethylene inhibitor, aminoethoxyvinylglycine (AVG) caused a greater regeneration frequency in P. cincinnata, whereas treatment with the ethylene precursor, 1-aminocyclopropane-1-carboxylic-acid (ACC) lessened regeneration frequencies. The data suggested that levels of polyamines and ethylene are not correlated with morphogenic responses in P. cincinnata. It was ascertained that neither the absolute ethylene and polyamine levels, nor competition between the compounds, correlated to the obtained morphogenic responses. However, sensitivity to, and signaling by, ethylene appears to play an important role in differentiation. This study reinforces previous reports regarding the requirement of critical concentrations and temporal regulation of ethylene levels for morphogenic responses. Temporal regulation also appeared to be a key factor in competition between the two biosynthetic pathways, without having any effects on morphogenesis. Further studies investigating the silencing or overexpression of genes related to ethylene perception, under the influence of polyamines in cell differentiation are extremely important for the complete understanding of this process.
