High temperature injury and auxin biosynthesis in microsporogenesis

open access: yesFrontiers in Plant Science, 2013
Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High temperature (HT) injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to HT.
