Unorganized callus and leaf/root-differentiating callus cultures of Pimpinella major have been established in liquid nutrient medium. Their capacity to accumulate rare phenylpropa­ noids such as epoxy-pseudoisoeugenol tiglate, epoxy-anol tiglate and anol tiglate was com­ pared with that of seedlings and whole plants. The unorganized callus cultures were not able to accumulate any phenylpropanoi...

Ground and whole Ditylenchus dipsaci maintained on onion callus contain no culturable micro-organisms when tested with five check media. Healthy onion callus does not produce pectolytic enzymes. Pectolytic enzymes are present in infected callus. These enzymes are, however, associated with resident nematodes and not host tissues. These results suggest that D. dipsaci is the actual source of the ...

Investigations were carried out to determine antimicrobial and antioxidant properties and total phenol content of three wild species of Ephedra compared with their respective callus cultures. Callus induction was performed in a standard Murashige and Skoog (MS) medium with the following hormonal ranges (mg/L) for every species NAA:1.5, Kin:1 for Ephedra strobiliacea, NAA:2, Kin:1 for Ephedra pr...

We describe mutant tissue lines of Arabidopsis that are able to grow in vitro as callus on hormone-free medium. The 14 lines presented here show different hormone autotrophic differentiation behaviors that can be classified into three categories: (a) forming roots (rooty callus), (b) forming shoots or shoot-like structures (shooty callus), or (c) growing without organ formation (callus). Three ...

Among the flowering plants, the members of cucurbitaceae are duly useful for human being that is agood source of vegetables and also a better resource for phytochemical compounds. The present study was aimed to induce the callus from in vitro grown seedling explants. The effect of BAP and NAA have been investigated, the combination of BAP and NAA results in the higher callus induction. The call...

Cereus peruvianus callus have a lot of alkaloids compounds and medicine extracted, which is important in medicine, medical and agricultural industries. The experiments were performed using Complete Randomized Design (CRD) and results were analyzed using one way ANOVA. MS medium supplemented with different concentrations of (2,4-D), kinetin and NAA were used. The study was carried out on Increas...

The objective was to study the different types of lengthened bone regeneration and their development during the various phases of the process to correlate them with patient factors and the surgical technique used, and to establish a possible relation between the development of the bone lengthening formation and the problems or complications. The authors studied the radiographs of a random group...

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...

Tephorsia purpurea Linn. (Fabaceae), commonly known as Saraphunkha, is an important indigenous medicinal plant used for centuries in Indian System of Medicine (ISM). It is an important ingredient of several marketed herbal formulations like Tephroli and Yakrifit used for liver disorders. Various plant parts have been used as remedy for impotency, asthma, diarrhoea, gonorrhoea, rheumatism, and u...
