Genetic engineering for heat tolerance in plants

Salinity tolerance in plants: Breeding and genetic engineering

Salinity stress limits crop yield affecting plant growth and restricting the use of land. As world population is increasing at alarming rate, agricultural land is shrinking due to industrialization and/or habitat use. Hence, there is a need to utilize salt affected land to meet the food requirement. Although some success has been achieved through conventional breeding but its use is limited due...

Genetic Basis for Heat Tolerance in Cattle

Heat tolerance in plants: An overview

Heat stress due to increased temperature is an agricultural problem in many areas in the world. Transitory or constantly high temperatures ause an array of morpho-anatomical, physiological and biochemical changes in plants, which affect plant growth and development and may ead to a drastic reduction in economic yield. The adverse effects of heat stress can be mitigated by developing crop plants...

Enhancement of Reproductive Heat Tolerance in Plants

Comparison of average crop yields with reported record yields has shown that major crops exhibit annual average yields three- to seven-fold lower than record yields because of unfavorable environments. The current study investigated the enhancement of pollen heat tolerance through expressing an Arabidopsis thaliana heat shock protein 101 (AtHSP101) that is not normally expressed in pollen but r...

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...
