The quality of wheat products has been a new challenge next to wheat production which was achieved substantially during green revolution. The end-use quality of wheat is an essential factor for its commercial demand. The quality of wheat is largely based on the wheat storage proteins which extensively influences the dough properties. High molecular weight glutenin subunits (HMWGS), low molecular weight glutenin subunits (LMWGS) and gliadins significantly influence the end-use quality. Genomics and proteomics study of these gluten proteins of bread and durum wheat have explored new avenues for precise identification of the alleles and their role in end-use quality improvement. Secalin protein of encoded by loci and is associated with 1RS.1BL translocation has been known for deterioration of end-use quality. Chromosomal manipulations using various approaches have led to the development of new recombinant lines of wheat without secalin. Advanced techniques associated with assessment of end-use quality have integrated the knowledge of useful or deteriorating HMWGS/LMWGS alleles and their potential role in end-use quality. This review gives a comprehensive insight of different aspects of the end-use quality perspective for bread making in wheat along with some information on the immunological interference of gluten in celiac disease.
小麦产品质量已成为继绿色革命期间小麦产量大幅提高之后的一项新挑战。小麦的最终用途质量是其商业需求的一个关键因素。小麦质量很大程度上取决于小麦贮藏蛋白,这些蛋白对面团特性有广泛影响。高分子量谷蛋白亚基(HMWGS)、低分子量谷蛋白亚基(LMWGS)和醇溶蛋白显著影响最终用途质量。对面包小麦和硬粒小麦这些面筋蛋白的基因组学和蛋白质组学研究为精确鉴定等位基因及其在改善最终用途质量中的作用开辟了新途径。由 位点编码且与1RS.1BL易位相关的黑麦碱蛋白已知会导致最终用途质量下降。采用各种方法进行的染色体操作已培育出不含黑麦碱的小麦新重组系。与评估最终用途质量相关的先进技术整合了有用或有害的HMWGS/LMWGS等位基因的知识及其在最终用途质量中的潜在作用。本综述全面深入地探讨了小麦用于面包制作时最终用途质量的不同方面,以及一些关于面筋在乳糜泻中的免疫干扰信息。
