YGL138(t), encoding a putative signal recognition particle 54 kDa protein, is involved in chloroplast development of rice.

ABSTRACT:

Background

Normal development of chloroplast is vitally important to plants, but its biological mechanism is still far from fully being understood, especially in rice.

Results

In this study, a novel yellow-green leaf mutant, ygl138, derived from Nipponbare (Oryza sativa L. ssp. japonica) treated by ethyl methanesulfonate (EMS), was isolated. The mutant exhibited a distinct yellow-green leaf phenotype throughout development, reduced chlorophyll level, and arrested chloroplast development. The phenotype of the ygl138 mutant was caused by a single nuclear gene, which was tentatively designed as YGL138(t). The YGL138(t) locus was mapped to chromosome 11 and isolated into a confined region of 91.8 kb by map-based cloning. Sequencing analysis revealed that, Os11g05552, which was p
