Identification of functional pathways and hub genes associated with the heterochronic development of sugarcane axillary buds and sett roots through multi-omics analysis.

ABSTRACT:

Introduction

Sugarcane is primarily propagated for large-scale agricultural production through vegetative reproduction by planting stem cuttings. Development of sprout and sett root from the cuttings is essential for sugarcane plant to adapt to the field environment. We observed asynchronous development during the sprouting of stem cuttings in two sibling sugarcane cultivars sharing the same parent in cross breeding: the axillary buds of cultivar ZZ2 (ZZ2B) sprout earlier, while the sett roots of ZZ9 (ZZ9R) emerge sooner.

Methods

Comparison of the sett root architecture, soluble sugar content, plant hormone levels and gene expression profiles during sprouting.

Results

We found that ZZ9 has a lower root cortex thickness ratio and a higher vascular cylinder thickness ra
