Several studies have reported physiological and molecular responses of tobacco to B deficiency, e.g., decline in nitrate content and nitrate reductase (NR) activity, increment in carbohydrate content, accumulation of chlorogenic acid, caffeoyl polyamine conjugates and phenylpropanoids, increment in phenylalanine ammonia-lyase (PAL) and polyphenoloxidase (PPO) activities in leaves [24,25,26], increment in putrescine levels in tobacco plants [27], and up-regulation of an asparagine synthetase ( AS ) gene and the glutamate dehydrogenase ( GDH ) genes in roots [28, 29]
In addition elevation of glucose utilization and the reduction of hepatic gluconeogenesis subsequent to the activation of peripheral opioid -receptors and the modification of genes involved in glucose metabolism (Liu and Cheng, ) are among suggested mechanisms
