Abstract:
... Premature leaf senescence has a profound influence on crop yield and quality. Here, a stable premature senescence mutant (GSm) was obtained from the common wheat (Triticum aestivum L.) cultivar Chang 6878 by mutagenesis with ethyl methanesulfonate. The differences between the GSm mutant and its wild-type (WT) were analyzed in terms of yield characteristics, photosynthetic fluorescence indices, and ...

Abstract:
... Ozone has been proposed as a convenient elicitor against pathogens since it is known to generate different reactive oxygen species (ROS) and induce nonspecific defence by altering gene expression. The mode of action and its interaction with other defence pathways are yet to be elucidated. Besides its negative effects on plants, ozone can be used for triggering defence against environmental stresse ...
