Project aims:1. Evaluate impact of crop management on f-Asn content of elite wheat germplasm, the role of nitrogen and sulphur fertilization, and the effects of other minerals and irrigation.2. Investigate the molecular basis for differential sulphur responses between varieties.3. Investigate diurnal regulation of f-Asn synthesis and breakdown in wheat.4. Characterise asparaginases naturally present in wheat grain.5. Analyse a soft wheat mapping population to identify QTL for f-Asn concentration.6. Screen elite varieties for the presence/absence of an f-Asn synthetase-2 gene on Chromosome 3B and evaluate the effect of the loss of this gene on f-Asn concentration in the grain. 7. Quantify the correlation between variation of f-Asn content in grains and AA content in baked goods

项目目标：1.评价作物管理对优良小麦种质f-Asn含量的影响，氮、硫肥的作用，以及其他矿物质和灌溉的影响.探讨品种间硫反应差异的分子基础.研究小麦f-Asn合成和降解的日变化规律.表征小麦籽粒中天然存在的天冬酰胺酶。对软质小麦作图群体进行f-Asn含量QTL定位.筛选优良品种的染色体3B上的f-Asn合成酶-2基因的存在/不存在，并评估该基因的缺失对籽粒中f-Asn浓度的影响。7.谷物中游离天冬酰胺含量变化与焙烤食品中氨基酸含量的相关性
