Arbuscular mycorrhizal fungi mediate leaf sugar profile in water-stressed trifoliate orange.

ABSTRACT:

Background

Arbuscular mycorrhizal fungi (AMF) enhance plant drought tolerance partly by promoting soluble sugar accumulation, the mechanisms by which AMF colonization influences host sugar metabolism and associated gene expression under drought remain poorly understood. This study therefore examined the effects of inoculation with Funneliformis mosseae (T.H. Nicolson & Gerd.) C. Walker & A. Schüßler on the growth, water status, sugar profiles, and the expression/activity of sucrose-associated genes in the leaves of trifoliate orange (Citrus trifoliata L.) under water stress conditions.

Results

Over a 10-week water stress period, the root colonization by F. mosseae decreased by 14.36%, compared with ample water controls. Under water stress, F. mosseae inoculation significantl
