Mitochondrial genome structural variants and candidate cytoplasmic male sterility-related gene in sugarcane.

ABSTRACT:

Background

Sugarcane is a crucial crop for both sugar and bioethanol production. The nobilization breeding and utilization of wild germplasm have significantly enhanced its productivity. However, the pollen sterility in Saccharum officinarum restricts its role to being a female parent in crosses with Saccharum spontaneum during nobilization breeding, resulting in a narrow genetic basis for modern sugarcane cultivars. Mitochondria, often referred to as the intracellular "energy factories", provide energy for plant life activities, and are also implicated in cytoplasmic male sterility (CMS).

Results

We performed mitochondrial genome assembly and structural analysis of two Saccharum founding species. We discovered that the proportions of repeat sequences are the primary factor
