Auxin controls Golgi-localized glucan synthetase activity in the maize mesocotyl.

Abstract

Decapitation or red light irradiation (R) inhibited growth and Golgi-localized glucan synthetase (GS I) activity in the mesocotyl of intact maize (Zea mays L.) seedlings. Applied auxin (indole-3-acetic acid) prevented the effects of R and of decapitation on both growth and GS I. Auxin applied several hours after irradiation prevented any further decline in GS I but did not restore it. Mesocotyl segments incubated in solution elongated in response to auxin but lost GS I with time regardless of the presence of exogenous auxin. An attached seed was necessary for maintenance of GS I in the dark-grown mesocotyl.
