To investigate the formation and regulation of floral scent during flower development, the flower developmental process from squaring stage to senescence stage was divided into six developmental stages with 12-h intervals (designated D1 to D6) (Fig. 1a).
This study investigated the development of scent emission and scent profile of narcissus cultivars of simple and double flower architecture.
In parallel, we tested differences in development of scent glands between males exhibiting different parasite load using an ANOVA.
To address whether this atlas of gene expression allows data mining to help initiating studies of specific functions in the rose, the following three important developmental processes related to flower development and scent were analyzed.
Together, these data demonstrate that the genetic event at the origin of 'St Anne's' altered mainly the petal number, but did not (or in a very limited manner) impact vegetative development or floral scent.
The development of the scent glands seems to be an honest signal for mate choice as it is negatively correlated with helminth load.
A parasitic queen may enter the host nest before the first brood has hatched, establishing herself prior to development of a colony scent.
We found that the development of the lateral scent glands of male voles was negatively correlated with helminth load.
These works have highlighted the usefulness of cDNA sequencing in the discovery of candidate genes for orchid floral development [ 16, 17], floral scent production [ 14, 18], and flowering time determination [ 19], in the absence of a full genomic sequence.
These studies have highlighted the utility of cDNA sequencing for discovering candidate genes for orchid floral development [ 19, 20], floral scent production [ 16, 21] or flowering time [ 22] in the absence of a genomic sequence.
