The short-term effect of nitrogen and phosphorus fertilizers on cold resistance in <i>Urtica cannabina</i> based on transcriptomics and metabolomics analysis.

ABSTRACT:

Introduction

Freezing injury in winter is a major abiotic stress that significantly limits plant growth and survival. While nitrogen and phosphorus fertilizers have been demonstrated to alleviate the impact of freezing injury in various plant species, their role of fertilizers in the cold tolerance of Urtica spp. is still unknown.

Methods

This study investigated the effects of fertilizers on the cold resistance of U. cannabina by comprehensively analyzing the physiological and biochemical indices, transcriptome, and metabolome of the U. cannabina under applications of 150 kg nitrogen ha-1 (N) and 90 kg phosphorus ha-1 (P), using "no fertilizer" (CK) as the control.

Results

The results showed that applying nitrogen and phosphorus fertilizers reduce
