Seedless mutant 'Wuzi Ougan' (Citrus suavissima Hort. ex Tanaka 'seedless') and the wild type were compared by iTRAQ-based quantitative proteomics and integratedly analyzed with transcriptome to improve understanding of male sterility.

ABSTRACT:

Background

Bud mutation is a vital method of citrus. 'Wuzi Ougan' (mutant type, MT) as a bud variant of 'Ougan' (wild type, WT) was first found in 1996 and has become popular because of its male sterility and seedless character. Previous analysis of its cytological sections and transcriptome revealed that the abnormal microsporogenesis that occurs before the tetrad stage of anther development might be the result of down-regulated oxidation-reduction biological processes in MT. To reveal the mechanism behind the male sterility in MT at the post-transcriptional stage, proteome profiling and integrative analysis on previously obtained transcriptome and proteome data were performed in two strains.

Results

The proteome profiling was performed by iTRAQ (isobaric Tags for relative
