LITERATURE
agriculture
-
transgenic Arabidopsis thaliana plants that overexpress CaAS1 exhibit enhanced resistance to Pseudomonas syringae pv. tomato DC3000 and Hyaloperonospora arabidopsidis. Increased CaAS1 expression influences early defense responses in diseased leaves, including increased electrolyte leakage, reactive oxygen species and nitric oxide burst. In CaAS1-silenced pepper and/or CaAS1-overexpressing Arabidopsis, CaAS1-dependent changes in asparagine levels correlate with increased susceptibility or defense responses to microbial pathogens, respectively

-
design of a silencing construct that simultaneously targets the expression of both isoforms StAs1and StAs2. Tubers of the transformed intragenic plants contain up to 20fold reduced levels of free asparagine. This coincides with a small increase in the formation of glutamine and does not affect tuber shape or yield. Heat-processed products derived from the low-asparagine tubers are indistinguishable from their untransformed counterparts in terms of sensory characteristics. However, both French fries and potato chips accumulate as little as 5% of the acrylamide present in wild-type controls
