摘要

We compared the effect of common bunt (caused by fungus Tilletia caries Tul.) and treatment with phytohormones IAA, ABA, and cytokinins (CK) on the activity of trypsin inhibitors (TI) in wheat seedlings. The experiments were conducted with pathogen-susceptible species of wheat Triticum aestivum L. (cv. Zhnitsa) and resistant species T. timopheevii Zhuk. (accession k-58666 from the collection of All-Russian Institute of Plant Industry). In the resistant wheat, the fungus elevated the activity of TI and the content of CK, whereas in the susceptible wheat, it induced accumulation of IAA. In the seedlings of wheat T. aestivum, TI activity increased under the effect of CK, same as upon the action of pathogen. ABA briefly increased the activity of TI, whereas IAA did not considerably affect it. It was concluded that among the investigated hormones, CK play a leading role in the regulation of defense responses of wheat plants involving TI.Notes Translated from Fiziologiya Rastenii (2012) 59 (6), 756-762 (Ru).
