Effects of salinity stress on morphological structure, physiology, and mRNA expression in different wheat (<i>Triticum aestivum</i> L.) cultivars.

ABSTRACT: Salinity is a major abiotic stress that threatens crop yield and food supply in saline soil areas. Wheat (Triticum aestivum L.) is the most important cereal crop in arid and semiarid land areas, which are often adversely affected by soil salinity. Hence, creating salt tolerance wheat is of great value for utilizing saline soils. In this study, two wheat cultivars QingMai 6 (QM6, salt-tolerant) and Chinese Spring (CS, salt-sensitive) were subjected to salinity stress. Morphological analysis showed that the seedlings of QM6 grew better than CS under salt stress conditions, especially in roots. Electron microscopic studies revealed that salinity stress caused significantly more root hairs and less effect on normal chloroplast structure in QM6 than these in CS. Moreover, QM6 showed a hi
