This work investigates food acceptability by analyzing key predictors and employing a statistical technique to assess the impact of physiochemical and microbial characteristics on various food types. Utilizing data from the Institute of Food Science and Technology in Dhaka, the study examines eight food categories and 678 products through Single Stage Cluster Sampling. It incorporates statistical methods to evaluate the significance of results, demonstrating the technique's adaptability and effectiveness in determining food quality and acceptability.
Drought significantly limits crop productivity and poses a major threat to global food security, especially with a growing population that could face serious food shortages by 2050. Predicted climate changes may exacerbate this issue by increasing the frequency and severity of droughts. To address this, it is crucial to enhance our understanding of drought tolerance mechanisms and develop crop varieties that are more resilient. Identifying genes linked to drought tolerance will shed light on the molecular processes that enable plants to cope with drought conditions. Discovering novel drought-related genes, analyzing their expression patterns, and understanding their roles in adaptation will inform strategies to improve drought resilience in crops. Current plant breeding efforts to boost yields in arid regions have been hindered by a limited understanding of the genetic mechanisms behind drought response and challenges in combining beneficial alleles. This volume presents recent findings on the molecular and genetic aspects of drought tolerance alongside modern crop improvement techniques. It offers a comprehensive overview of existing data and practical knowledge, integrating classical and molecular genetics with cutting-edge omic technologies. This resource is valuable for educators and researchers in plant breeding, molecular biology, and biotechnology.
Abiotic stress significantly impacts global crop production, reducing average yields by up to 50%. Among these stresses, drought is the primary cause of yield loss worldwide. With the global population projected to rise, the threat of food shortages by 2050 due to drought stress is alarming. This situation is exacerbated by climate change, which is expected to increase the frequency and severity of such stresses. Therefore, there is an urgent need to enhance our understanding of drought stress tolerance mechanisms and develop resilient crop varieties. Identifying novel genes linked to drought tolerance is crucial for unraveling the molecular responses of crops to drought. Discovering these genes, analyzing their expression under drought conditions, and understanding their roles in adaptation will inform effective engineering strategies to boost drought resilience. While the intricate mechanisms of water stress tolerance remain partially understood, they can be partially explained through ion homeostasis, toxic radical scavenging, osmolyte biosynthesis, water transport, and signaling coordination. However, fully elucidating the physiological, biochemical, and molecular processes involved in drought perception, transduction, and tolerance remains a challenge for plant biologists. The findings in the first volume emphasize the physiological and biochemical aspects of drought stress affecting crop productivity, while the second vo
