Durum wheat ears perform better than the flag leaves under water stress: Gene expression and physiological evidence

Drought is the main abiotic stress threatening wheat production in the Mediterranean region. While the negative effect of drought on the photosynthetic carbon and nitrogen metabolism of the flag leaf has been widely studied, little is known about its effect on other photosynthetic organs such as the ear. Our study compared the responses to water stress of organ temperature, spectral vegetation indices, nitrogen content, carbon isotope...
