Breeding crops with a higher ability in using soil minerals is one of the biotechnology researchers’ goals. Genetic engineering methods provide considerable advances in crop breeding by transferring and creating desired traits for further production under normal or stress conditions. In these procedures, Design of efficient gene constructs is of particular importance and requires promoters with proper function to specifically express the gene of interest in the target tissue and at the appropriate time to develop desired traits such as tolerance to biotic and abiotic stresses or other aims. Specific expression of phosphate-transporter genes in the roots and their induced levels in phosphate deficiency shows the potential of this gene-family promoters utilization in transgenic plants, particularly for the use in phosphate absorption from soil. Bioinformatics analysis showed that the 1826-bp promoter fragment of AtPHT1;1 gene carries several motifs leading to root-specific expression in Arabidopsis thaliana. The expression of a secretory acid phosphatase gene, AtPAP17, as a reporter gene in rapeseed transgenic plants indicated that the AtPHT1;1 promoter retains its root-specific criteria in rapeseed such that it could be used as a regulatory region for the specific expression of desired genes in transgenic rapeseed plant roots.

Obesity increases inflammatory indices and creates insulin resistance, and proper diet along with regular physical exercises are effective in improving these indices. Therefore, the aim of this study was to investigate 10 weeks of calorie restriction along with alkaline, acidic diet and functional exercises on lipid profile, body composition and C-reactive protein levels in obese and overweight adults. In this semi-experimental research, 53 obese and overweight adults (18 men, 35 women) with an average age of 35.4±8.3 years voluntarily participated. Calorie restriction along with alkaline and acidic diet and functional exercises were applied in three experimental groups and one control group for 10 weeks. Body composition (weight, waist-hip ratio, body mass index, muscle and fat mass, visceral fat), lipid indices (fasting cholesterol, high-density lipoprotein, low-density lipoprotein, triglyceride) and C-reactive protein levels were measured. Anukova and Bonferroni tests were used to compare groups in the post-test and the significance level was 0.05. body composition (weight, body mass index, waist-to-hip ratio, fat mass and visceral fat) and cholesterol decreased in the alkaline diet group along with calorie restriction and functional exercises in overweight and obese people (P≥0.05). Calorie restriction and alkaline diet by reducing acid load along with 10 weeks of functional training lead to improvement of body composition and cholesterol in overweight and obese adults.
