New Guinea Impatiens (Impatiens hawkeri W. Bull) is an eye-popping landscaping plant of bright and colorful blooms. A highly efficient in vitro regeneration system via direct shoot organogenesis was established for the first time from hypocotyl with partial cotyledons Impatiens. Our results showed that explant sterilization method, basic medium type, AgNO3, sucrose growth regulators have signif...

Six tetraploid Alstroemeria clones were micropropagated by rhizome multiplication, a system whereby the shoots were cut off from the rhizome and discarded. In a three-week subculture interval, the average rhizome multiplication rate for all genotypes was 2.3. In one selected genotype the discarded shoots were used to initiate another micropropagation system: the leafy explant micropropagation s...

An in vitro culture system leading to the formation of callus and plant regeneration, starting from nodal sections and shoot tips, was developed for Solidago chilensis (Asteraceae). The content of the gastroprotective diterpene solidagenone as well as the phenolics chlorogenic acid (CA) and rutin was determined either in rhizomes from wild growing plants and in callus and in in vitro regenerate...

A novel, efficient, and direct blend of solvents, tetrabutylammonium acetate/dimethyl sulfoxide (TBAA/DMSO), was used for the dissolution and regeneration of bamboo pulp. Regenerated fibers were successfully prepared by a wet spinning process. The bamboo pulp without any pretreatment was readily soluble in the solvent under mild conditions. The dissolution process was observed using a confocal ...

The axolotl can regenerate multiple organs, including the brain. It remains, however, unclear whether neuronal diversity, intricate tissue architecture, and axonal connectivity can be regenerated; yet, this is critical for recovery of function and a central aim of cell replacement strategies in the mammalian central nervous system. Here, we demonstrate that, upon mechanical injury to the adult ...

Lallemantia iberica (Bieb.) Fisch. and C. A. Mey is high valued annual ornamental and medicinal plant from Lamiaceae family that prefers dry sunny hillsides, roadsides, slopes, and fallow fields over an altitude of 500-2150 m. It bears beautiful white flowers and bloom from April to June each year. This study reports L. iberica micropropagation using cotyledon node explants isolated from 15-day...
