Background & Aim: Sweet basil (Ocimum basilicum), a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta, confectioneries and other products as both a fresh and dried herb. The effect of foliar application of Jasmonic acid and reduced irrigation on essential oil yield and chemical components of two Iranian landrace of basil (<e...

background &amp; aim: recent researches have been done on effects of plant growth regulators (pgr) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. the application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation...

Leaf trichomes protect plants from attack by insect herbivores and are often induced following damage. Hormonal regulation of this plant induction response has not been previously studied. In a series of experiments, we addressed the effects of artificial damage, jasmonic acid, salicylic acid, and gibberellin on induction of trichomes in Arabidopsis. Artificial damage and jasmonic acid caused s...

Jasmonic acid and its metabolites are ubiquitously occurring lipid-derived signaling compounds that regulate growth, development and defense processes in flowering plants. However, their functions in lower land plants have not been well characterized yet. The model moss, Physcomitrella patens is a member of bryophytes and represents a key evolutionary position between green algae and flowering ...

Salicylic acid, jasmonic acid, methyl salicylate, and methyl jasmonate are important phytohormones and defensive signaling compounds, so it is of great importance to determine their levels rapidly and accurately. The study uses Ulmus pumila leaves infected by Tetraneura akinire Sasaki at different stages as materials; after extraction with 80% methanol and ethyl acetate and purification with pr...

Natural plant hybrid zones have been described as 'sinks' and 'centers of biodiversity' for herbivores and fungal pathogens. Jasmonic acid is known to be a critical signaling molecule for defense against these enemies. Does inhibition of jasmonic acid perhaps contribute to the susceptibility of hybrid plants to attack by herbivores? Here, we discuss recent evidence that plant immune system inco...

Objective: In order to study the effect of drought stress, salicylic acid (SA) and  jasmonic acid (JA) foliar application on H...

background &amp; aim:jasmonic acid (ja) is regarded as endogenous regulators that play important roles in regulating stress responses, plant growth and development.effect of foliar application of ja on the essential oil and oil chemical components of hyssop (hyssopus officinalis l.) were investigated. experimental:  this study conducted in a crd with three replications and in experimental green...

Sex determination in maize is controlled by a developmental cascade leading to the formation of unisexual florets derived from an initially bisexual floral meristem. Abortion of pistil primordia in staminate florets is controlled by a tasselseed-mediated cell death process. We positionally cloned and characterized the function of the sex determination gene tasselseed1 (ts1). The TS1 protein enc...
