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.

“…1b, c, e). The positive effect of silver ion on shoot bud multiplication and elongation has been shown by various studies earlier (Brar et al 1999;Hyde and Phillips 1996;Pestana et al 1999;Giridhar et al 2003;Sridevi and Giridhar 2014;Sgamma et al 2015;San et al 2015). Elongated shoots were harvested for root induction and remaining hypocotyls along with small shoot buds were again placed on media supplemented with 8.88 μM BAP in combination with 108.6 μM Ads and 11.84 μM AgNO 3 .…”

A reproducible protocol developed for in vitro regeneration of Milletia pinnata using hypocotyl segments. Multiple shoots were induced from hypocotyl explants through direct adventitious shoot bud regeneration. The proximal end of hypocotyls was responsive for shoot bud induction. Silver nitrate and adenine sulphate had a positive effect on shoot bud induction and elongation. The maximum response and number of shoot bud produced in media supplemented with 8.88 μM BAP with 108.6 μM adenine sulphate and 11.84 μM silver nitrate. Elongated shoots were harvested and successful rooting of microshoots achieved on MS media supplemented with 9.84 μM IBA, with 81.1 % rooting. Remaining shoot buds sub-cultured for further multiplication and elongation. Each subculture produced eight to nine elongated microshoots up to four subcultures. The rooted microshoots were successfully hardened and transferred to field.

“…Sub-culturing of these embryo clusters reported to produce more secondary embryos on reduced TDZ (0.01-0.2 mg l -1 ) containing medium and subsequently developed into plantlets followed by rooting on MS basal medium. Shoots of arabica and robusta coffee showed increased growth when cultured on MS medium containing AgNO 3 , IAA and BA (Giridhar et al 2003). Incorporation of AgNO 3 at 10-40 lM concentration in the culture medium enhanced growth of both C. arabica and C. canephora coffee (Giridhar et al 2003).…”

Coffee is an important plantation crop grown in about 80 countries across the globe. In recent years, coffee attained lot of attention in the biotechnology research area. Since last three decades, there has been a steady flow of information on coffee biotechnology and now it is entering into the genomic era. Major milestones in coffee biotech research are successful in vitro manipulation and multiplication of coffee, development of gene transfer protocols and generation of transgenic coffee plants with specific traits. The isolation of genes involved in caffeine biosynthetic pathway has opened up new avenues for generating caffeine free transgenic coffee. With the initiation of international coffee genomics initiatives, the genomic research in coffee is expected to reach new dimensions. The IPR issues may play crucial role in sharing of benefits during international collaborations in near future. This review focuses on the basic and applied aspects of coffee biotechnology for newer potentials.
