Notizen: Abstract In many cropping regions of the world, yield is limited by the availability of micronutrients, and micronutrient-efficient cultivars provide a yield advantage. Traditional methods of testing cultivars for micronutrient efficiency are time-consuming and laborious. Molecular markers linked to loci controlling micronutrient efficiency will allow more rapid and efficient selection and introgression of these traits than is currently possible. Using a pot-based bioassay and bulked segregant analysis of an F2 population, we have identified several RFLPs (grouped distally on chromosome 4HS) linked to a locus for manganese efficiency in barley. This manganese efficiency locus has been designated Mel1. Pot bioassay analysis of intercrosses suggests that three useful sources of manganese efficiency are likely to be allelic at the Mel1 locus. Field evaluation of marker selected F4 progeny supports the major role of Mel1 in the genetic control of manganese efficiency. Adoption of marker assisted selection for this trait in the Southern Australian barley breeding program has occurred. This has been facilitated by the demonstration that the Mel1 allele of Amagi Nijo can be distinguished from 95 other locally useful varieties and breeder’s lines on the basis of RFLPs identified by just two molecular markers.

Notizen: The chromogenic tripeptide substrate, benzyloxycarbonylglycyl-L-prolyl-L-citrulline p-nitroanilide, is proposed for the assay of the high-alkaline proteinase, HAP-PB92, from an alkalophilic Bacillus. The assay method is sensitive, reproducible, and may be adapted for an automatic system.

Notizen: Instrumental parameters and possible correction procedures for hydrogen-transfer phenomena are studied, with emphasis on the improvement of quantitative measurements in selected ion monitoring mass spectrometry. The intensity ratio of the m/z 387 and 386 ions, derived from cholesterol, are measured by an HP-5995 mass spectrometer using different parameters, including calibration peak width, mass filter window size and ion monitoring dwell time. The intrinsic ratio of these two ions is calculated with a correction procedure accounting for the [M—H]+ and [M—2H]+ hydrogen-transfer phenomena.
