Development of introgression lines and mapping of , a novel QTL that confers grain width, in rice ( L.).

Unlabelled: Rice grain size is a key determinant of both grain yield and quality. Identification of favorable alleles for use in rice breeding may help to meet the demand for increased yield. In this study, we developed a set of 210 introgression lines (ILs) by using variety Huanghuazhan as the donor parent and erect-panicle rice variety Wuyujing3R as the recurrent parent.

Mapping of Rf20(t), a minor fertility restorer gene for rice wild abortive cytoplasmic male sterility in the maintainer line 'Zhenshan97B'.

Three-line hybrid rice has primarily been developed on wild abortive (WA)-type cytoplasmic male sterility (CMS) and has helped increase the yield of rice globally. The development of WA-type CMS lines and hybrids was expedited through the identification and mapping of the fertility restorer gene (Rf) in maintainers. This study observed fertile plants in WA-TianfengA/Zhenshan97B//TianfengB population, indicating that the maintainer line 'Zhenshan97B' should carry Rfs for WA-type CMS.

The Effects of Rf4 and the Genetic Mechanism Behind Fertility Restoration of Wild Abortive Cytoplasmic Male Sterility (WA-CMS) in Japonica Rice (Oryza sativa ssp. Japonica).

Wild abortive-type cytoplasmic male sterility (WA-type CMS) has been exclusively used in hybrid seed production in indica rice cultivars, and fertility restoration in WA-type CMS is controlled by two major restorer genes, Rf3 and Rf4, through a sporophytic mechanism. However, the genetic mechanism underlying fertility restoration in WA-type CMS in japonica cultivars is poorly understood. In the present study, C418, a leading Chinsurah Boro II- (BT)-type japonica restorer line, showed partial restoration ability in WA-type japonica CMS lines.

Precise genetic mapping of Rf18(t), a new fertility restorer gene from 'Nipponbare' for wild abortive cytoplasmic male sterility in rice (Oryza sativa L.).

We mapped Rf18(t), a Restorer-of-fertility gene for wild abortive cytoplasmic male sterility from the japonica maintainer 'Nipponbare', to chromosome 1. The best candidate gene, LOC_Os01g71320, is predicted to encode hexokinase. Three-line hybrid rice obtained through cytoplasmic male sterility (CMS) has helped increase the yield of rice globally, and the wild abortive (WA)-type cytoplasm from wild rice (Oryza rufipogon Griff.

The effects of and on fertility restoration in Honglian-type cytoplasmic male sterile (CMS) lines of rice ( L. ssp. ).

Unlabelled: Honglian (HL)-type cytoplasmic male sterility (CMS) has only been used in the development of three-line rice hybrids, and the fertility of HL-type CMS lines can be restored by two non-allelic fertility-restorer () genes, and . For the development of HL-type hybrid combinations, it is therefore necessary to determine whether and can restore the fertility of HL-type CMS lines. Here, we genetically characterized HL-type CMS lines and the ability of and to restore fertility for breeding HL-type hybrids.

Overexpression of the Transcription Factor Gene OsSTAP1 Increases Salt Tolerance in Rice.

Background: High soil salinity can cause significant losses in rice productivity worldwide, mainly because salt inhibits plant growth and reduces grain yield. To cope with environmental changes, plants have evolved several adaptive mechanisms that involve the regulation of many stress-responsive genes.

Results: In this study, we identified OsSTAP1, which encodes an AP2/ERF-type transcription factor, was rapidly induced by ABA, ACC, salt, cold, and PEG treatments.

[Improvement of the bilingual teaching of genetics using classic papers].

More and more colleges have recognized the importance of bilingual teaching in improvement students' capability to integrate the specialized knowledge with the foreign language. Bilingual teaching courses have been designed to enhance the innovation of high education and improve the culture quality of students. Genetics is one of the most important courses for undergraduate students majored in the region of life sciences.

[A preliminary exploration into medical genetics teaching to international students].

Medical education to international students has become an important part of higher education in China. Medical genetics is an essential and required course for international medical students. However, the internationalization of higher education in China has challenged the traditional teaching style of medical genetics.

[Molecular mapping of two semidwarf genes in an indica rice variety Aitaiyin3 (Oryza sativa L.)].

The rice dwarf variety Aitaiyin3 is derived from a semidwarf cultivar Taiyin1. Genetic analysis indicated that the dwarf phenotype in Aitaiyin3 is involved in two recessive loci. Using bulk analysis with SSR markers, the two loci were located on the chromosome 1 and chromosome 4, respectively.
