In the present study, a mutated chimericorf364, namedorf366-c, was identified in a maize C type cytoplasmic male sterile line (CMS-C) by PCR and RT-PCR. Four base pair adjacent base substitution mutations (CAAA to TTTT) and eight bp insertion mutations were found inorf366-ccompared withorf364. ORF366-C was predicted to contain one membrane-spanning domain using TMHMM online software. Real-time quantitative PCR analysis showed thatorf366-cwas upregulated in the CMS-C line in comparison to its maintainer line at the uninucleate stage. The protokaryotic protein expression oforf366-cinEscherichia colishowed that ORF366-C could be a cytotoxic protein. All the results indicated thatorf366-cmay be associated with maize CMS-C.

Abstract The identification and development of new cytoplasmic male sterility (CMS) lines in higher plants is important for the preservation of grain security and the prevention of homogenization of hybrid rice. Molecular markers assisted selection (MAS) based on CMS-associated genes or mitochondrial-specific chimeric sequences are important for rapid and effective breeding of new CMS lines and hybrids. In our study, the distribution and allele variation of orfH79 and orf290 genes were characterized from 273 wild and cultivated rice in the AA genome species. Based on the alignment of nucleotide and amino acid sequences, four accessions with orfH79 and three accessions with orf290 were screened. Four novel CMS lines carrying orfH79 haplotypes and three novel CMS lines carrying orf290 haplotypes were then developed using multiple backcross generations with a maintainer line under MAS. The breeding process used in our study provides an efficient and feasible approach for selecting new CMS lines. CMS lines selected in our study are important for enriching rice germplasm resources and guaranteeing rice breeding programs.

Significant variations were obtained among the component lines for most of the floral traits. BRRI9A exhibited superiority for angle of open florets, stigma length and breadth, anther breadth, filament length, style length and panicle exertion rate while its corresponding maintainer lines BRRI9B showed superiority for duration of open florets, stigma length and breadth, anther breadth and filament length. This indicated BRRI9A and its corresponding maintainer line BRRI9B possessed very good floral traits that influence out crossing. Among the restorer lines BR168R showed superiority for duration of open florets, angle of open florets, duration of bloomed florets/panicle, stigma length, anther length and number of pollen/microscopic focus. This suggested BR168R could be used as promising restorer line with BRRI9A for hybrid seed production in local condition.DOI: http://dx.doi.org/10.3329/bjb.v43i1.19739 Bangladesh J.
