“…However, with the exception of E, we were unable to find evidence for induced VOC emission in A. thaliana treated with caeliferin A16:0. Although A. thaliana has been successfully used in numerous plant-insect and VOC biosynthesis studies, it is generally recognized that A. thaliana flowers and foliage emit exceedingly low VOC levels (48,49). Given the slow kinetics (20-30 h) and low reported rates of VOC emission (3-5 ng g Ϫ1 h Ϫ1 ), it is possible that small effects of caeliferin A16:0 on induced VOC production may have been missed (48).…”

In response to insect attack, many plants exhibit dynamic biochemical changes, resulting in the induced production of direct and indirect defenses. Elicitors present in herbivore oral secretions are believed to positively regulate many inducible plant defenses; however, little is known about the specificity of elicitor recognition in plants. To investigate the phylogenic distribution of elicitor activity, we tested representatives from three different elicitor classes on the time course of defense-related phytohormone production, including ethylene (E), jasmonic acid (JA), and salicylic acid, in a range of plant species spanning angiosperm diversity. All families examined responded to at least one elicitor class with significant increases in E and JA production within 1 to 2 h after treatment, yet elicitation activity among species was highly idiosyncratic. The fatty-acid amino acid conjugate volicitin exhibited the widest range of phytohormone and volatile inducing activity, which spanned maize (Zea mays), soybean (Glycine max), and eggplant (Solanum melongena). In contrast, the activity of inceptinrelated peptides, originally described in cowpea (Vigna unguiculata), was limited even within the Fabaceae. Similarly, caeliferin A16:0, a disulfooxy fatty acid from grasshoppers, was the only elicitor with demonstrable activity in Arabidopsis thaliana. Although precise mechanisms remain unknown, the unpredictable nature of elicitor activity between plant species supports the existence of specific receptor-ligand interactions mediating recognition. Despite the lack of an ideal plant model for studying the action of numerous elicitors, E and JA exist as highly conserved and readily quantifiable markers for future discoveries in this field.ethylene ͉ insect elicitor ͉ jasmonic acid ͉ plant defense ͉ volatile organic compound

“…Rosewood (Aniba rosaeodora Ducke, Lauraceae) is an Amazonian tree that produces an essential oil which is in great demand both in Brazil and internationally. Rosewood oil contains large amounts of linalool, a compound widely used by the cosmetics industry (Vainstein et al, 2001) but which may also have therapeutic properties as an anesthetic (Ghelardini et al, 1999) and an antimicrobial agent (Rosa et al, 2003;Inouye et al, 2001) that may lead to the development of new products. Due to commercial demand, rosewood populations have decimated in its center of origin in the Amazon forest but a small number of individual trees continue to exist in the Brazilian states of Amazonas and Pará (Rosa et al, 1997).…”

Nuclear DNA content and karyotype of Rosewood (Aniba rosaeodora)

Rosewood (Aniba rosaeodora Ducke, Lauraceae) is ecologically and economically important to the Amazon region. As a consequence of its economic importance, rosewood populations have been decimated in the Amazon forest. Species of nine genera of the Lauraceae family have characterized karyotypes with n = x = 12 chromosomes in the gametophytic phase but the genus Aniba is one of the least studied Lauraceae genera with a previously undescribed genome. We used cytogenetic techniques to determine that the A. rosaeodora karyotype contained 12 pairs (2n = 24) of relatively small submetacentric chromosomes with lengths ranging from 1.34 to 2.25 mm and a nucleolar organizer region (NOR) in the short arm of chromosome 7. Flow cytometry gave 2C = 2.32 pg of DNA, equivalent to approximately 2.24 x 10 9 base pairs.

“…There is no convenient plant model system that allows chemical and biochemical studies on floral scents. The well-established Arabidopsis as a plant model system failed to serve this purpose as the detection of volatiles production by its flower was barely detectable (Vainstein et al, 2001). To date, the characterization and elucidation of enzymes and genes involved in flower scent production are still not as advanced as the biochemical study on the scent constituents.…”

“…However, volatile esters formation is not restricted to plant kingdom but also in yeast and fungi especially in the fermentation industry (Beekwilder et al, 2004). Floral scent is made up of a complex mixture of low-molecular-weight lipophilic compounds which are typically liquids with high vapour pressures (Vainstein et al, 2001). With the discovery of novel techniques including gas chromatography-nuclear magnetic resonance (GC-NMR), gas chromatography-mass spectrometry (GC-MS), headspace based techniques in volatiles detection and analyses, the number of identified volatile compounds has increased tremendously (Gonzalez-Mas et al, 2008;Mohd-Hairul et al, 2010;Nojima et al, 2011).…”
