hyssop (hyssopus officinalis l.), belongs to the family of lamiaceae which its origin is asia minor, and is considered as one of the most important medicinal plant. this experiment was done to study the effects of population and bap concentrations on hyssop plant regeneration under in vitro culture conditions. this research were performed in factorial experiment with three populations (hamadan,...

Plants, unlike animals, have plastic organ growth that is largely dependent on environmental information. However, so far, little is known about how this information is perceived and transduced into coherent growth and developmental decisions. Here, we report that the growth of Arabidopsis is positively correlated with the level of expression of the TARGET OF RAPAMYCIN (TOR) kinase. Diminished ...

Because the farmer is typically excluded from the experimental research setting, experimental research may face challenges in evaluating pest management tactics whose costs and benefits hinge on farmer decision-making. In these cases an ecoinformatics approach, in which observational data collected from the commercial farming setting are "mined" to quantify both biological variables and farmer ...

Role of humic acids (HA) in plant tissue culture as plant growth regulators has been reviewed. Humic acid is a principal component of humic substances, which are the most important organic constituents of the soil (humus). Humus is defined as the organic matter in soil, a mixture of partially and totally humified substances. Leonardite is the best source for humic acid and it is extracted by us...
