Comparative transcriptional analysis of Capsicum flower buds between a sterile flower pool and a restorer flower pool provides insight into the regulation of fertility restoration.

ABSTRACT:

Background

Cytoplasmic male sterility (CMS) and its restoration of fertility (Rf) system is an important mechanism to produce F₁ hybrid seeds. Understanding the interaction that controls restoration at a molecular level will benefit plant breeders. The CMS is caused by the interaction between mitochondrial and nuclear genes, with the CMS phenotype failing to produce functional anthers, pollen, or male gametes. Thus, understanding the complex processes of anther and pollen development is a prerequisite for understanding the CMS system. Currently it is accepted that the Rf gene in the nucleus restores the fertility of CMS, however the Rf gene has not been cloned. In this study, CMS line 8A and the Rf line R1, as well as a sterile pool (SP) of accessions and a restorer pool
