A Pelota-like gene regulates root development and defence responses in rice.

ABSTRACT:

Background and aims

Pelota (Pelo) are evolutionarily conserved genes reported to be involved in ribosome rescue, cell cycle control and meiotic cell division. However, there is little known about their function in plants. The aim of this study was to elucidate the function of an ethylmethane sulphonate (EMS)-derived mutation of a Pelo-like gene in rice (named Ospelo).

Methods

A dysfunctional mutant was used to characterize the function of OsPelo. Analyses of its expression and sub-cellular localization were performed. The whole-genome transcriptomic change in leaves of Ospelo was also investigated by RNA sequencing.

Key results

The Ospelo mutant showed defects in root system development and spotted leaves at early seedling stages. Map-based cloning revealed that the m
