Abstract:Arbuscular
mycorrhizae (AM) symbiosis can enhance plant resistance
to drought stress (DS). This study aimed to investigate the DS effects
on lipids at different stages of symbiosis and to link lipid profiles
to arbuscule dynamics in tomato roots colonized by AM fungi. DS increased
mycorrhizal colonization and arbuscule abundance at an early stage
but decreased them at a later stage, delayed arbuscule development,
and accelerated arbuscule senescence at a later stage. DS decreased
the contents of phospholipids … Show more
