If expression levels of olfactory genes could be linked with functional responses to volatiles, expression profiling could lead to a better understanding of the function and operation of olfactory genes and could elucidate how individual variation of olfactory gene expression might lead to speciation or resistance to pheromonal pest management.
Thus in populations of lox2/3 and lox2/3x Tplantslants deficient in all HIPVs except for the engineered TPS10 volatiles, TPS10 expression by edge plants increased predator activity on those plants.
Shelf-life ripening was also used to increase the complexity of our data set and to evaluate the effect on volatile and gene expression.
The amounts of volatiles and gene expression data were analyzed by using ANOVAs followed by Holm-Sidak post-hoc tests.
A number of candidate genes for peach volatiles were identified using a combination of data analysis techniques based on correlations between gene expression and volatile accumulation data (HCA, PC, and CNA).
These plants were characterized by using a combination of volatile, phytohormone and gene expression profiling approaches to investigate in more detail the process of BA emission.
Volatile concentration and MdAFS1 expression were significantly affected by 1-MCP, since its application reduced both VOCs and MdAFS1 accumulation almost completely.
Furthermore, the emissions of floral volatile compounds and the expression patterns of genes involved in the floral scent formation were analyzed.
To analyze the shelf-life response of the 'MxR_01' and 'Granada' genotypes, we compared the changes in volatile content and gene expression.
In order to obtain a global view of the interrelationships between volatile accumulation and gene expression, a Pearson correlation analysis was conducted for all the possible volatile gene pairs (Additional file 8: Table S5).
