Some plant growth-promoting rhizobacteria (PGPR) regulated plant growth and elicited plant basal immunity by volatiles. The response mechanism to the Bacillus amyloliquefaciens volatiles in plant has not been well studied. We conducted global gene expression profiling in Arabidopsis after treatment with Bacillus amyloliquefaciens FZB42 volatiles by Illumina Digital Gene Expression (DGE) profili...

Volatiles from flowers at three blooming stages of nine citrus cultivars were analyzed by headspace-solid phase microextraction (HS-SPME)-GC-MS. Up to 110 volatiles were detected, with 42 tentatively identified from citrus flowers for the first time. Highest amounts of volatiles were present in fully opened flowers of most citrus, except for pomelos. All cultivars were characterized by a high p...

Due to declining dairy cow fertility rates, there is great interest in developing tools for oestrus detection. Compounds in the volatile profile of oestrous cows are suggested as oestrus-specific, but consistent results have not been presented. Certain haematophagous arthropods can discriminate stages of the mammalian reproductive cycle based on host volatiles. This study investigated whether t...

Endoclita signifer is a major wood-boring pest of eucalyptus trees in China, and its third instar larvae can accurately find infest mixed-species forests, although it also feed on another 51 tree species the same planted area. A total 34 volatile compounds were identified from trunks, including non-infested infested trunks with single or multiple (more than three) larval entrance cover packets,...

Whey edible films (EFs) functionalized with essential oils have a high potential to be used on various foods due their antimicrobial and antioxidant activities. Encapsulation is applied for better retention of volatiles in EFs; however, the functional properties EFs are modified. The containing thyme oil (TEO) encapsulated by co-precipitation β-CD, developed three formulae, inclusion complexes ...

Bacterial volatiles protect plants either by directly inhibiting a pathogenic fungus or by improving the defense capabilities of plants. The effect of bacterial volatiles on fungal growth was dose-dependent. A low dosage did not have a noticeable effect on Botrytis cinerea growth and development, but was sufficient to elicit induced resistance in Arabidopsis thaliana. Bacterial volatiles displa...

ABSTRACT Irradiation dose affected production of volatiles in vacuumand aerobic-packaged cooked pork sausage, but its effect on TBARS was minor. Storage increased production of volatiles and changed their composition only in aerobic-packaged sausage. Among volat...

Like other organisms, plants have endogenous biological clocks that enable them to organize their metabolic, physiological, and developmental processes. The representative biological clock is the circadian system that regulates daily (24-h) rhythms. Circadian-regulated changes in growth have been observed in numerous plants. Evidence from many recent studies indicates that the circadian clock r...

C5 volatile compounds, derived from fatty acids, are among the most important contributors to consumer liking of fresh tomatoes. Despite their important roles in flavour, the genes responsible for C5 volatile synthesis have yet to be identified. This work shows that their synthesis is catalysed in part by a 13-lipoxygenase (LOX), TomloxC, the same enzyme responsible for synthesis of C6 volatile...

laurus nobilis l. (sweet laurel) is one of the volatile oil bearing plants of lauraceae family. it is cultivated in different parts of iran and its leaves and fruits have been used in food, cosmetics and pharmaceutical industries. there are a few reports about the effects of some environmental conditions on the quality and quantity of laurel volatiles. the goal of our work was to search the sea...
