Transcriptome and metabolome analysis of Cycas bifida response to low-temperature stress.

ABSTRACT:

Background

Cycas bifida is an endemic species distributed in limited areas of Yunnan and Guangxi, with a notably small population size. Under the context of global climate warming, this species may require introduction to colder habitats. Previous studies have confirmed its weak cold tolerance. To thoroughly investigate the molecular and metabolic mechanisms underlying its response to low temperature, this study employed low-temperature stress treatments combined with transcriptome sequencing and metabolomics technologies for systematic comparative analysis.

Results

Through multi-omics analysis, this study identified 1,960 differentially expressed genes in Cycas bifida under cold stress, showing an overall upregulation trend. Pathway enrichment analysis confirmed galactose m
