taxus    is an endangered plant which is the only commercial source of paclitaxel, which is used for treatment of ovary and breast cancer. as production of this valuable drug is a destructive process, other alternatives should be considered for its sustainable production. plant tissue and cell culture is a promising method for production of secondary metabolites. in order to optimize yew callus...

Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...

shoot tips from actively growing, greenhouse maintained plants of kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on murashige and skoog (ms) basal medium supplemented with naa and ba, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...

Communication between distant organs is an essential feature of multicellular organisms. Plants are no exception to this rule and long-range signals are involved in the regulation of many aspects of organ growth and development. In this review, we use two specific examples to illustrate this point. The first is a novel upwardly mobile hormone involved in the regulation of shoot branching. The s...
