Eremurus spectabilis M. Bieb, a perennial herbaceous wild species, is commonly used in the horticultural, ornamental, and pharmaceutical markets. Studies on tissue culture systems for this species would be beneficial mass multiplication as well future breeding programs. An vitro propagation technique was established here using tuberous root explants unique responsive starting materials initiati...

A protocol for direct shoot regeneration without intervening callus phase was developed by shoot tip culture of MS (murashinge and skoog) medium for teak. The study reveal that aseptically inoculated shoot tip of teak in established shoot induction and shoot multiplication was also observed at same concentration .At BAP 1mg/l, IAA 1mg/l and kin 1mg/l the shoots were weak ,tiny and non separable...

An efficient and reproducible procedure was established for direct shoot regeneration of Solanum surattense Bum. using internodal explants. The shoot regeneration efficiency on Murashige and Skoog (MS) medium supplemented with 6benzylaminopurine (BAP) was superior in compared to 6furfurylaminopurine (Kn). The highest mean number of shoots per explant was recorded on MS medium containing 0.5 mgl...

Cells of yellow-poplar (Liriodendron tulipifera L.) were transformed by direct gene transfer and regenerated into plants by somatic embryogenesis. Plasmid DNA bearing marker genes encoding beta-glucuronidase (GUS) and neomycin phosphotransferase (NPT II) were introduced by microprojectile bombardment into single cells and small cell clusters isolated from embryogenic suspension cultures. The nu...

A protocol for direct organogenesis in Bixa orellana (pink flowers variety) has been developed with significant organogenic response from rooted hypocotyls, hypocotyl segments, and cotyledonary leaf explants on Murashige and Skoog (MS) medium supplemented with 2.0 mg L thidiazuron and 0.25% coconut water or 7.0 mg L N-Benzyladenine and 0.1 mg L a-naphthalene acetic acid. Thidiazuron in combinat...

Self-maintenance of the shoot apical meristem (SAM), from which aerial organs are formed throughout the life cycle, is crucial in plant development. Class I Knotted1-like homeobox (KNOX) genes restrict cell differentiation and play an indispensable role in maintaining the SAM. However, the mechanism that positively regulates their expression is unknown. Here, we show that expression of a rice (...

The percent study describes the in vitro responses of mature zygotic embryos of Boscia senegalensis to different concentrations (0.0-5.0 mg/L) of 6-benzyladnine (BA), Thidiazuron (TDZ), α-Naphthalene acetic acid (NAA), and 2, 4-Dichlorophenoxyacetic acid (2, 4-D) supplemented on Murashige and Skoog medium (MS). The plant growth regulators (PGRs) were considerably affected the morphogenetic resp...

To accelerate breeding of Pinus massoniana Lamb. resistance to pine wilt disease (PWD), caused by the pinewood nematode (PWN), Bursaphelenchus xylophilus, a protocol was established for in vitro propagation P. and evaluation regenerated microshoots from different clones PWN. Axillary bud induction achieved culturing cotyledonary node explants 3-week-old seedlings Gupta Durzan (DCR) medium that ...
