Effect of tobacco mosaic virus infection on the endogenous levels of iaa phenyl acetic acid and abscisic acid of tobacco leaves in various stages of development



Effect of tobacco mosaic virus infection on the endogenous levels of iaa phenyl acetic acid and abscisic acid of tobacco leaves in various stages of development



Zeitschrift fuer Pflanzenphysiologie 83(5): 403-410



Young leaves surrounding the shoot apex and the next 10 morphologically apical leaves on 12 wk old tobacco (Nicotiana tabacum cv. Mammoth) plants were abraded with a suspension of the tomato streak strain of tobacco mosaic virus (TMV). Leaves were collected 24, 48 and 72 h post infection, and their endogenous contents of IAA, phenylacetic (PAA) and abscisic (ABA) acids were determined by isothermal gas chromatography (GC). In the healthy, uninoculated leaves the level of IAA increased from the apical leaves up to leaf 2, then decreased gradually up to leaf 8, and again increased slightly in leaves 9 and 10. A similar trend was seen with respect to PAA and ABA levels though the maximum contents of these substances were found in leaf 1. Within 24 h of virus application, there was a considerable reduction in the levels of the acids, especially in the younger apical leaves. These low levels were maintained at 48 and 72 h sampling periods in all the leaves; PAA and ABA levels showed slight recovery 72 h after infection. The amounts of tryptophan (Try) and phenylalanine (Phe), the precursors of IAA and PAA, respectively, increased considerably in the infected leaves at all 3 sampling periods as compared to the controls. Diversion of substrates for the synthesis of new virus particles is probably the cause of the reduction in the levels of the growth substances. Gibberellin-like activity could not be detected in any of the healthy or diseased leaves.
