Overexpression of a wheat aquaporin gene, TaAQP8, enhances salt stress tolerance in transgenic tobacco.
Aquaporin (AQP) proteins have been shown to transport water and other small molecules through biological membranes, which is crucial for plants to combat salt stress. However, the precise role of AQP genes in salt stress response is not completely understood in plants. In this study, a PIP1 subgroup AQP gene, designated TaAQP8, was cloned and characterized from wheat. Transient expression of Ta...
متن کاملTaCIPK29, a CBL-Interacting Protein Kinase Gene from Wheat, Confers Salt Stress Tolerance in Transgenic Tobacco
Calcineurin B-like protein-interacting protein kinases (CIPKs) have been found to be responsive to abiotic stress. However, their precise functions and the related molecular mechanisms in abiotic stress tolerance are not completely understood, especially in wheat. In the present study, TaCIPK29 was identified as a new member of CIPK gene family in wheat. TaCIPK29 transcript increased after NaCl...
متن کاملTHE EFFECT OF SALT STRESS ON MALATE DEHYDROGENASE IN WHEAT
Effect of various NaCI treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swollen, flowering and anthesis) of two wheat cultivars on the kinetic activity and PAGE electrophoretic pattern of leaf malate dehydrogenase was studied under greenhouse conditions. Ghods was salt-sensitive and Boolani was salt-tolerant. In general, in response to salinti...
متن کاملExpression of a bacterial mtlD gene in transgenic tobacco leads to production and accumulation of mannitol.
A bacterial gene encoding mannitol-1-phosphate dehydrogenase, mtlD, was engineered for expression in higher plants. Gene constructions were stably incorporated into tobacco plants. The mtlD gene was expressed and translated into a functional enzyme in tobacco, resulting in the synthesis and accumulation of mannitol, which was identified by NMR and mass spectroscopy. Mannitol concentrations exce...
