| T1 |
0-92 |
Sentence |
denotes |
C6-volatiles derived from the lipoxygenase pathway induce a subset of defense-related genes. |
| T2 |
93-395 |
Sentence |
denotes |
Six-Carbon (C6-) volatiles, including the aldehydes trans-2-hexenal, hexanal and cis-3-hexenal, as well as their corresponding alcohols, are produced from damaged or wounded plant tissue as a product of the enzymatic activity of hydroperoxide lyase (HPL), a component of the lipoxygenase (LOX) pathway. |
| T3 |
396-639 |
Sentence |
denotes |
Aerial treatment of Arabidopsis seedlings with 10 microM concentrations of trans-2-hexenal induces several genes known to be involved in the plant's defense response, including phenylpropanoid-related genes as well as genes of the LOX pathway. |
| T4 |
640-729 |
Sentence |
denotes |
Genes encoding the pathogenesis-related proteins PR-1 or PR-2, however, were not induced. |
| T5 |
730-859 |
Sentence |
denotes |
Trans-2-hexenal induction thus closely mimics the group of genes induced by methyl jasmonate (MeJA), also a LOX-derived volatile. |
| T6 |
860-977 |
Sentence |
denotes |
However, unlike MeJA, trans-2-hexenal did not induce hydroxymethylglutaryl-coenzyme A reductase (HMGR) or thionin2-1. |
| T7 |
978-1116 |
Sentence |
denotes |
The inductive effect seemed to be limited to C6-related volatiles, as C8-, C9- and other related volatiles did not induce LOX mRNA levels. |
| T8 |
1117-1218 |
Sentence |
denotes |
As has been demonstrated for MeJA, trans-2-hexenal quantitatively reduced wild-type seed germination. |
| T9 |
1219-1416 |
Sentence |
denotes |
Trans-2-hexenal also reduced the germination frequency of the MeJA resistant Arabidopsis mutant, jar1-1, supporting the notion that trans-2-hexenal and MeJA are recognized via different mechanisms. |
| T10 |
1417-1654 |
Sentence |
denotes |
In addition, trans-2-hexenal had a moderate inhibitory effect on root length relative to similar concentrations of MeJA and was approximately 10-fold less effective than MeJA at inducing anthocyanin accumulation in Arabidopsis seedlings. |
| T11 |
1655-1850 |
Sentence |
denotes |
These results suggest that C6-volatiles of the LOX pathway act as a wound signal in plants, but result in a moderate plant response relative to MeJA at both the physiological and molecular level. |
