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 کاملMetabolic engineering of osmoprotectant accumulation in plants.
Drought and salinity are among the worst scourges of agriculture. One effective mechanism to reduce damage from these stresses is the accumulation of high intracellular levels of osmoprotectant compounds. These compounds include proline, ectoine, betaines, polyols, and trehalose and have evolved in many different organisms. Since some crop plants have low levels of these osmoprotectants or none...
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 کاملThe Role of Micronutrients in Crop Production and Human Health
The soils in Pakistan across 22 Mha cultivated area are predominantly alluvial and loessal, alkaline in pH, calcareous and low in organic matter. These factors are mainly responsible for nutrient fixation in soil and low availability to plants. Zinc (Zn) deficiency in Pakistan was the first micronutrient disorder recognised in early 1970s as a cause of hadda disease in rice. After identificatio...
متن کاملEnhancement of folates in plants through metabolic engineering.
Humans depend on plants as a major source of dietary folates. Inadequate dietary levels of the vitamin folate can lead to megaloblastic anemia, birth defects, impaired cognitive development, and increased risk of cardiovascular disease and cancer. The biofortification of folate levels in food crops is a target for metabolic engineering. Folates are synthesized de novo from pterins and para-amin...
