[Genome-wide analysis and functional prediction of the Trihelix transcription factor family in rice].

The Trihelix transcription factor family plays an essential role in plant growth, development and stress response. However, the studies about identification and analysis of this gene family in rice on the genome-wide level have not been reported. In this study, 31 members of the Trihelix family, which contain highly conserved and characteristic trihelix domain through sequence clustering and functional domains analysis, were identified in rice genome database using bioinformatic tools.

[Discrimination of the Triticum aestivum-T. timopheevii introgression lines using PCR-based molecular markers].

In order to determine the fragment size of Triticum timopheevii chromosome segments introduced into wheat background and physically map the Pm6 gene, a total of 72 primers (including SSR and STS primers) were used to analyze the eight introduced introgression lines containing Pm6 gene. Referring to the available mapping information of the analyzed markers on chromosome 2B, Pm6 was physically located in distal part of the long arm of chromosome 2B at the region of Bin 2BL-6. The introgressed fragment sizes of the chromosome 2G in different introgression lines was determined to be as follow (from short to long): IGV1-465 View Article and Find Full Text PDF
