Title of the seminar:Genetic engineering of lignin using a bacterial gene
Host

Room: Lilla hörsalen KB3A

Lignin is one of the major components of the plant cell wall.
It is an aromatic polymer with different types of chemical linkage. The m
ost abundant linkage unit in typical native dicot lignin is the ß-aryl eth
er (ß–O–4) unit\, which accounts for over 50% of all units. The benzylic ß
-positions of ß–O–4-units are usually hydroxy-substituted. The ß-keto-ß–O–
4 units\, with carbonyl groups at the benzylic positions\, are also found
in natural lignins at very low concentrations. These ß-keto ß–O–4 units ca
n be cleaved under alkaline and/or oxidative conditions more easily and fa
ster than the typical ß–O–4-units with benzylic hydroxyl groups. Thus\, in
creasing the abundance of ß-keto-ß–O–4 units as opposed to the typical ß-h
ydroxy-ß–O–4 units in the lignin backbone can contribute to a reduction in
the cost and energy required for chemical pulping and biomass pretreatmen
t processes in cellulosic ethanol production.
Sphingobium sp. s
train SYK-6 \, a gram-negative bacterium\, can utilize various monomeric a
nd dimeric aromatic compounds that are intermediates in the lignin biosynt
hetic pathway\, such as cinnamic acid\, cinnamaldehyde\, and ß–O–4 dimers.
In our previous studies\, we isolated and characterized a lot of genes fr
om the bacterium\, which were involved in the degradation of these compoun
ds. One of the genes\, ligD\, encodes C? dehydrogenase\, which catalyzes t
he first step in the cleavage of the ether bond of ß–O–4 dimers. This enzy
me oxidizes the alcohol group at benzyl position of the dimers and oligome
rs to the carbonyl group. Thus\, in the present study\, we introduced ligD
into the plant genome and attempted to generate transgenic plants whose l
ignin can be easy to remove from the holocellulose fraction. Recombinant L
igD \, and transgenic Arabidopsis plants with ligD and their lignins have
been characterized by chemical\, biochemical\, and genetic methods.
