Transcriptome analysis reveals plant hormone signal transduction mechanisms underlying freezing stress responses in Cycas panzhihuaensis.

ABSTRACT:

Background

Global warming intensifies climate extremes, with rising temperatures and more frequent heatwaves. This situation may make it more difficult for species in high-temperature regions, such as the Cycas panzhihuaensis. Introduction and domestication are vital for conservation, but low temperatures limit the spread of tropical and subtropical plants to higher latitudes and altitudes. Phytohormones mediate cold adaptation through complex signaling networks that regulate physiological and molecular responses. However, the hormonal regulation and molecular mechanisms underlying freezing tolerance in C. panzhihuaensis remain poorly understood.

Results

This study used C. panzhihuaensis as the research subject. We exposed the plant to freezing stress and measures leaf hormo
