Follicle-stimulating hormone regulates pro-apoptotic protein Bcl-2-interacting mediator of cell death-extra long (BimEL)-induced porcine granulosa cell apoptosis.

The pro-apoptotic protein Bim (B-cell lymphoma-2 (Bcl-2)-interacting modulator of cell death) has recently been identified and shown to promote cell death in response to several stimuli. In this report, we investigated the role of Bim in porcine follicular atresia. Initially, Bim cDNA was cloned and characterized from porcine ovarian tissue.

Construction of a bacterial artificial chromosome (BAC) library of common wild rice (Oryza rufipogon Griff.) for map-based cloning of genes selected during the domestication of rice.

As a prerequisite for the map-based cloning of genes from common wild rice (Oryza rufipogon Griff.), which plays an important role in the domestication of cultivated rice (O. sativa L.

[Mapping QTLs controlling vascular bundle and panicle-related traits from Yuanjiang common wild rice (Oryza rufipogon Griff.)].

An advanced backcross population (BC3F2), derived from the cross between Yuanjiang common wild rice as the donor parent and Teqing as recurrent parent, was used to map QTLs controlling the number of vascular bundle and panicle-related traits from Yuanjiang common wild rice. Seven QTLs controlling the number of large vascular bundles in peduncle were detected on chromosome 1, 2, 3, 4, 7 and 10. Five QTLs for the number of small vascular bundles in peduncle were mapped on chromosome 1, 2, 3, 4 and 8.

[Identification of quantitative trait loci controlling plant height and days to heading from Yuanjiang common wild rice (Oryza rufipogon Griff.)].

An advanced backcross strategy was used to identify quantitative trait loci (QTLs) associated with plant height and days to heading in the BC3F2 population derived from an accession of common wild rice (Oryza rufipogon Griff.) from Yuanjiang in Yunnan Province of China, as the donor, and an elite Indica cultivar "Teqing", as the recipient. Based on analyses of 116 SSR markers distributed throughout the rice genome and by using single-point analysis, four putative QTLs derived from O.
