Lycopene is present in a range of fresh fruits and vegetables, especially in the leaves of Barringtonia racemosa. The traditional lycopene extraction from the plant is being employed instead of an easy propagation technique like cell culture process from the leaf explants. We intend to assess how lycopene could be extracted via tissue culture under light (illuminance: 8,200 lux under white fluo...

Rapid in vitro multiplication of shoots has been described using capitular sections and leaf explants in Gerbera jamesonii. Three types of basal media regimes were used including MS and two of its modified forms⎯MSI and MSA. Shoot induction was achieved on all three regimes but MSI medium supplemented with Kn (4 mg/l) and IAA (0.5 mg/l) was ideal for shoot bud initiation (8-11) from capitular s...

An efficient in vitro protocol has been established for somatic embryogenesis and plantlet conversion of Korean wild ginseng (Panax ginseng Meyer). Wild-type and mutant adventitious roots derived from the ginseng produced calluses on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L 2,4-dichlorophenoxyacetic acid and 0.3 mg/L kinetin; 53.3% of the explants formed callus. Embryogenic ca...

Eostrobilopshumicolus Páll-Gergely & Hunyadi, sp. n. is described from Guangxi Province, China. It is characterized by the combination of a small shell (diameter: 2.3-2.4 mm), strongly ribbed dorsal surface, an infraparietal lamella not reaching the callus, and long basal folds. The new species is found approximately 500 and 800 km from the two nearest species Eostrobilopsinfrequens (northern V...

abstract an investigation was accomplished during 2007 and 2008 to test effect of hormonal treatment and cutting position on rooting of sebri , shekari and natanz cultivars of pear (pyrus pyrifolia.) the experimental design was a two way factorial in a completely randomized method and with pgr5 treatment (iba and iba with naa in four levels in the first year and four higher levels of iba in sec...

Root induction by auxins is still not well understood at the molecular level. In this study a system has been devised which distinguishes between the two active auxins indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA). IBA, but not IAA, efficiently induced adventitious rooting in Arabidopsis stem segments at a concentration of 10 microM. In wild-type plants, roots formed exclusively ou...

Ficus lyrata is a popular ornamental foliage plant with unique violin- or guitar-shaped green leaves. In our previous study, grapevine gene VvMybA1 was introduced into F. via Agrobacterium-mediated transformation, which resulted in the availability of purple-leaved plants. Since transcription factor, regeneration transgenic plants might potentially produce variants multicolored The objective th...

<i>Verbascum scamandri</i> Murb. known as "Kazdağı Mullein" is an endemic species in Türkiye and classified endangered (EN) species. The aim of this study to establish efficient callus culture for <i>V. analyze the amounts verbascoside, luteolin, aucubin metabolites calli samples. Leaf explants were cultured on MS medium with cytokinin (BAP, Kin, 0, 0.5, 1, 2, 3 mg/L) auxin (N...

Stress fractures are overuse injuries of bone that affect elite athletes and military recruits. One response of cortical bone to stress fracture is to lay down periosteal callus. The objectives of this study were to determine if material properties are different among bones with different stages of stress fracture callus, at both a callus site and at a distal site. Cortical specimens were mecha...

Rye is second only to wheat among grains most widely used in the making of bread and is also a very important gene resource for breeding and improvement of wheat and other cereal crops owing to tolerance to abiotic stress factors such as low temperatures, drought and poor soil conditions. However, application of biotechnologies has been limited in rye breeding since it is one of the most recalc...
