BACKGROUND AND AIMS Leafy vegetable Brassica crops are an important source of dietary calcium (Ca) and magnesium (Mg) and represent potential targets for increasing leaf Ca and Mg concentrations through agronomy or breeding. Although the internal distribution of Ca and Mg within leaves affects the accumulation of these elements, such data are not available for Brassica. The aim of this study wa...

This paper briefly examines current methodology for developing genetic linkage maps and using them to find loci for quantitative traits (QTL). Maximum likelihood interval mapping is viewed as an extension of classical least squares methods when the trait of interest is normally distributed and located near a genetic marker. Some problems in finding multiple loci for a quantitative trait are exa...

Improving crop species by breeding for salt tolerance or introducing salt tolerant traits is one method of increasing crop yields in saline affected areas. Extensive studies of the model plant species Arabidopsis thaliana has led to the availability of substantial information regarding the function and importance of many genes involved in salt tolerance. However, the identification and characte...

Following polyploidy, duplicate genes are often deleted, and if they are not, then duplicate regulatory regions are sometimes lost. By what mechanism is this loss and what is the chance that such a loss removes function? To explore these questions, we followed individual Arabidopsis thaliana-A. thaliana conserved noncoding sequences (CNSs) into the Brassica ancestor, through a paleohexaploidy a...

BACKGROUND Audio computer-assisted self-interview (ACASI) may elicit more frequent reporting of socially sensitive behaviours than face-to-face (FtF)-interview. However, no study compared responses to both methods in female and male sex workers (FSW; MSW) in Africa. METHODOLOGY/PRINCIPAL FINDINGS We sequentially enrolled adults recruited for an HIV-1 intervention trial into a comparative stud...

THERE can be little doubt that the spectre of false rape allegations has significantly influenced the development of legal doctrine and its enforcement. The fear of false allegations has been used to justify evidential rules in cases involving sexual offences such as the corroboration warning,' the retention of the marital rape immunity' and continues to influence police and prosecutorial decis...

Iturin A and surfactin are antimicrobial lipopeptides produced by antagonistic Bacillus spp. We herein demonstrated that both lipopeptides amended the soil-mediated suppression of the soil-borne disease, Fusarium yellows of tatsoi (Brassica rapa var. rosularis). Significant disease suppression was conferred by the amendments of purified iturin A or surfactin to soil. However, an excess amount o...

Protein preparations from Arabidopsis thaliana and Brassica rapa catalyzed the formation o f O-sinapoyl-L-malate using 1-O-sinapoyl-ß-glucose as acyl donor. The enzyme involved, 1-O-sinapoyl-ß-glucose :L-malate O-sinapoyltransferase (SMT; EC 2 .3 .1 .-) , catalyzes in the cotyledons o f the seedlings the key step in the conversion o f the seed constituent sinapine (O-sinapoylcholine) to sinapoy...
