Agrobacterium tumefaciens

The gill tissues of this mushroom42 contain the interesting imine quinone (35). Agrobacterium tumefaciens 

The crown-gall tumour that is induced by certain strains of this micro-organism contains a number of interesting amino-acids, but agropine (36). a novel bicyclic derivative of glutamic acid, has recently been isolated and is present in quantities of up to 7% of the dry weight of the tumour.43 

This sponge contains three high-molecular-weight bromotyrosine derivatives,44 i.e. fistularin-1 (37), fistularin-2 (38), and fistularin-3 (39).

A novel decarboxylase, 2,6-dihydroxybenzoate decarboxylase, was found in Agrobacterium tumefaciens 1AM 12048 at first. Thereafter, the same activity was found in Rhizobium species by two groups independently. Furthermore, Pandoraea sp. 12B-2, the most powerful producer of 2,6-dihydroxybenzoate decarboxylase, was isolated. These enzymes have been purified and characterized.

Oxidation Products of Sucrose. The essentially regiospecific oxidation by Agrobacterium tumefaciens, whose dehydrogenase exclusively generates 3 -ketosucrose, is the prototype of an entry reaction into modified sucroses. This ready access opened the way to manifold modifications at the 3 -carbonyl function (Scheme 2.16)." Chemical oxidation proceeds less uniformly, for... 

In an attempt to influence flavor characteristics, CHS antisense and overexpression constructs were introduced into grapefruit by Agrobacterium tumefaciens [16, 59]. CHS overexpression constructs were shown to lead to morphological abnormalities and frequently to death, while a number of CHS antisense constructs resulted in a statistically significant reduction in flavonoid content in the transgenic plants even though there was a large variation in the flavonoid concentration [16].
