Engineering Cold Stress Tolerance in Crop Plants
Plants respond with changes in their pattern of gene expression and protein products when exposed to low temperatures. Thus ability to adapt has an impact on the distribution and survival of the plant, and on crop yields. Many species of tropical or subtropical origin are injured or killed by non-freezing low temperatures, and exhibit various symptoms of chilling injury such as chlorosis, necro...
متن کاملEngineering pathogen resistance in crop plants: current trends and future prospects.
Transgenic crops are now grown commercially in 25 countries worldwide. Although pathogens represent major constraints for the growth of many crops, only a tiny proportion of these transgenic crops carry disease resistance traits. Nevertheless, transgenic disease-resistant plants represent approximately 10% of the total number of approved field trials in North America, a proportion that has rema...
متن کاملEngineering crop plants: getting a handle on phosphate.
In plant seeds, most of the phosphate is in the form of phytic acid. Phytic acid is largely indigestible by monogastric animals and is the single most important factor hindering the uptake of a range of minerals. Engineering crop plants to produce a heterologous phytase improves phosphate bioavailability and reduces phytic acid excretion. This reduces the phosphate load on agricultural ecosyste...
متن کاملefl students gender and socioeconomic status: the use of politeness strategies in the first and second languages
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
Genetic engineering of glycinebetaine synthesis in plants: current status and implications for enhancement of stress tolerance.
Metabolic acclimation via the accumulation of compatible solutes is regarded as a basic strategy for the protection and survival of plants in extreme environments. Certain plants accumulate significant amounts of glycinebetaine (betaine), a compatible quaternary amine, in response to high salinity, cold and drought. It is likely that betaine is involved in the protection of macrocomponents of p...
