The endophytic fungal populations of different tissues of Taxus baccata grown at high altitudes in West Bengal, India were explored. These isolated fungal populations represented different genera, which were screened for taxol production using immunoassay technique. The culture AAT-TS-4(1) that produced taxol was identified as Gliocladium sp. based on its cultural, morphological characteristics...

In vitro cultivated plant cells and tissues were found to synthesize polyisoprenoids. Taxus baccata suspension cell cultures accumulated polyisoprenoids of the same pattern as the parental tissue; methyl jasmonate or chitosan treatment almost doubled their content. All the root cultures studied accumulated dolichols as predominant polyisoprenoids. Roots of Ocimum sanctum grown in vitro accumula...

Female individuals of dioecious plants invest their resources more in storage and defence, the males have higher nitrogen content invested production pollen grains. An unresolved problem is whether this strategy occurs only sexually mature or can also occur juvenile plants. To answer this, Taxus baccata (L.) needles from rooted cuttings (juveniles) a pot experiment were compared for carbon, nit...
