A cross-sectional study on maternal anxiety levels after cytomegalovirus screening.

we aimed to estimate the anxiety levels of pregnant women following maternal serum screening for CMV infection. In this case-control study conducted from April 2016 to June 2017, we enrolled all pregnant women referred to our hospital who were CMV immunoglobulin (Ig) M antibody positive (IgM-positive group,  = 51); further, those who were CMV IgG positive but IgM negative (IgM-negative group,  = 51) during the same period were included as study controls. Data were collected on patient characteristics, CMV IgM levels, and whether patients were accompanied by their partners during the first hospital visit after CMV IgM testing.

Development of chromosome segment substitution lines harboring genomic segments in Koshihikari and evaluation of yield-related traits.

Chromosome segment substitution lines (CSSLs) are rich genetic resources that can be mined for novel, agriculturally useful loci or that can be used directly as materials for breeding. To date, a number of rice CSSLs have been developed by crossing rice cultivars with its wild relatives as a means to tap into the potential of wild alleles in rice improvement. is a wild relative of rice that is thought to be a progenitor of spp.

Construction of a versatile SNP array for pyramiding useful genes of rice.

DNA marker-assisted selection (MAS) has become an indispensable component of breeding. Single nucleotide polymorphisms (SNP) are the most frequent polymorphism in the rice genome. However, SNP markers are not readily employed in MAS because of limitations in genotyping platforms.

Convergent Loss of Awn in Two Cultivated Rice Species Oryza sativa and Oryza glaberrima Is Caused by Mutations in Different Loci.

A long awn is one of the distinct morphological features of wild rice species. This organ is thought to aid in seed dispersal and prevent predation by animals. Most cultivated varieties of Oryza sativa and Oryza glaberrima, however, have lost the ability to form long awns.

Development and evaluation of chromosome segment substitution lines (CSSLs) carrying chromosome segments derived from Oryza rufipogon in the genetic background of Oryza sativa L.

The wild relatives of rice (Oryza sativa L.) are useful sources of alleles that have evolved to adapt in diverse environments around the world. Oryza rufipogon, the known progenitor of the cultivated rice, harbors genes that have been lost in cultivated varieties through domestication or evolution.
