Abstract Producing high value-added products from waste lipid feedstock by microbial cell factory has great advantages to minimize the pollution as well improve economic value of wasted oils and fats. Yarrowia lipolytica is a non-conventional oleaginous yeast can grow on variety hydrophobic substrates. In this study, we explored its ability synthesize α-farnesene, an important sesquiterpene, us...

The composition of the essential oils of Teucrium chamaedrys L. belongs to the family Lamiaceae, It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. In this research, essential oils of T. chamaedrys, extracted and measured at the different location by different methods of distillationand then were analyzed by GC and GC/MS. Investigation and comparison o...

To characterize the role of the phytotoxin mimic 6-substituted indanoyl isoleucine conjugate 1 in plant secondary metabolism, tobacco (Nicotiana tabacum L. K326) was treated with compound 1. The volatile compounds of tobacco leaves were analyzed by GC-MS. In contrast to the control, three compounds, farnesene (2), santalol (3) and tetradecanal (4), were induced by treatment with 1 mM of compoun...

The importance of chamomile (Chamomilla recutita) inflorescence is widely known in classical and folk medicine, with the largest group its effective constituents forming essential oil (chamazulene, a-bisabolol, α-farnesene, trans-β-farnesene, spathulenol, cis/trans-en-in-dicycloethers). Among cultivated species, Hungarian BK-2 contains more chamazulene than German Degumil type, which mainly for...

The effect of four temperatures (18, 20, 25 and 30°C) on pupa development and sexual maturity of Anastrepha obliqua adults was investigated under laboratory conditions. The results showed that the duration of the pupal stage decreased with an increase in temperature (29, 25, 13 and 12 days, respectively), and maintaining the pupae at 18°C and 20°C results in a low percentage of pupation, pupa w...

Insects trigger plants to release volatile compounds that mediate the interaction with both pest and beneficial insects. Soybean aphids (Aphis glycines) induces soybean (Glycine max) leaves to produce volatiles that attract predators of the aphid. In this research, we describe the use of solid-phase microextraction (SPME) for extraction of volatiles from A. glycines-infested plant. Objectives w...

In this paper we report on the large induction of volatile organic compounds (VOCs) from a single leaf of the mossy sorrel, Rumex confertus Willd. (Polygonaceae), by herbivory of the red dock weevil (Apion miniatum Germ., Coleoptera: Apionidae). VOC blends induced by the red dock weevil herbivory included 5 green leaf volatiles (GLVs) ((Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexenol, (E)-2-hexenol,...
