Wounding plants

Uses. Hydroxyhydroquinone has been used in hair and mordant dyes, for healing plant wounds, and in corrosion inhibitors and adhesives.

Attempts to produce cellulose from UDP-Glc using enzymes of isolated plasma membranes from higher plants have usually yielded the ( -1,3-linked glucan (callose) instead. This is a characteristic polysaccharide of plant wounds which, as healing occurs, is degraded and replaced by cellulose.140144 Callose... 

Plant tumors result from uncontrolled hormone production. Crown gall tumors, for example, are due to the infection of plant wounds by certain strains of Agrobacterium. These bacteria carry a large plasmid, the tumor-inducing, or T, plasmid, part of which is incorporated into the plant genome. This DNA encodes several genes that stimu-...

Thus, good substrates for the tea chloroplast enzyme system consisting of lipoxygenase and hydroperoxide lyase were llnolelc acid and linolenlc acid which are commonly occurring fatty acid In plant tissues particularly after acyl hydrolysis of lipids on aging, injury and processing etc. The resultant products are volatiles Including hexanal, (3Z)-hexenal and (2E)-hexenal which are responsible for characteristic odor of plant products. In addition 12-oxo-(9Z)-dodecenolc acid and 12-oxo-(10E)-dodecenolc acid reported as plant wound hormone are formed as a counterpart of volatile C -aldehydes.

Traumatic Acid, the plant wound hormone, is liberated by damaged tissues, and stimulates growth of parenchymatous celk in the repair process. It has been isolated by English (1939) and shown to be 1 — decene — 1, 10 — dicarboxylic acid, HOOC. CH = CH. (CH ),. CHij. COOH.
