Transcriptome time-course analysis unravels the regulatory networks governing ratooning decline in sugarcane.

ABSTRACT:

Introduction

Ratooning cultivation is the predominant production mode for sugarcane, yet ratooning decline represents a critical constraint limiting high and stable yields. To elucidate the molecular mechanisms underlying this phenomenon, this study aimed to reveal the critical period of sugarcane ratooning decline and variety-specific regulatory networks by integrating multi-year field yield data with transcriptome analysis.

Methods

This study combined five consecutive years of field yield data (from plant cane to the fourth ratoon, PC-R4) with root time-course transcriptome data from three sugarcane varieties (YT93-159, YZ05-51, and YZ08-1609). Differentially expressed genes (DEGs) were identified, followed by Mfuzz time-course clustering, Weighted Gene Co-expression Netwo
