Transgenic plant lines

Nowadays the genome of many plant species have been sequenced. This amount of information may be useful in the studies regarding plant responses to HS. For example, mutant or transgenic plant lines may be used in order to discover new aspects on this area. 

Leaf tissue from untransformed Russet Burbank, transgenic plant line AFP24-1 and Ch aska where brought from 22 to -2 C in one hour and then held at that temperature for up to 3 additional hours. 

Such observations led to the hypothesis that regulated expression of PL3 in transgenic potatoes could contribute to enhanced tissue disintegration during storage or thermal treatment. This report addresses the properties of several independent transgenic potato plant lines that express PL3, either constitutively or tuber-specific. We also describe the results obtained following application of Erwinia bacteria to wounded potato tubers. 

Additionally, the content of free and total acids as a measure of the degree of pectin esterification was investigated (Fig. 2). The amounts of both free and total acids were increased in the transgenic plants. However, their ratios are not significantly affected when both plant lines are compared (Fig. 2).

In order to overcome environmental concerns in particular, some companies are investigating the use of engineered plant cell lines as opposed to intact transgenic plants in the context of biopharmaceutical production. One company (DowAgroSciences) gained approval in 2006 for a veterinary subunit vaccine against Newcastle disease in poultry produced by such means.
