Physiological and transcriptome changes induced by exogenous putrescine in anthurium under chilling stress.

ABSTRACT:

Background

Chilling stress is the major factor limiting plant productivity and quality in most regions of the world. In the present study, we aimed to evaluate the effects of putrescine (Put) and polyamine inhibitor D-arginine (D-arg) on the chilling tolerance of anthurium (Anthurium andraeanum).

Results

Anthurium seedlings were pretreated with five different concentrations of Put solution or D-arg solution. Subsequently, the seedlings were subjected to chilling stress at 6 °C for 3 days, followed by a recovery at 25 °C for 1 day. Relative permeability of the plasma membrane, as well as physiological and morphologic parameters was assessed during the experiments. Additionally, transcriptome sequencing and patterns of differential gene expression related to chilling response
