This study clearly shows that development of wheat anthers and pollen is affected by B deficiency. It also shows a good correlation between anther length and pollen development. In B-deficient wheat, the pollen does not accumulate starch and the nuclei when present are abnormal. It has been suggested that B-deficiency affects pollen development during the pollen mother cell stage. The results show that B is essential for wheat pollen germination and pollen tube growth. B may play a role in the control of protein secretory activity in pollen tubes through the redistribution and capture of materials including (and especially) protein from membrane fusion events involving vesicles, which lead to pollen tube extension
